Overview

Programmable AC power source DP series (DP240S / DP360S) and DP series Type R (DP150RS /DP180RS) are 24 kVA / 36 kVA / 15 kVA / 18 kVA single phase AC stabilized power source which
inherit the performance and function of DP series. It provides various interfaces such as the external
control input/output, communication interface, and remote controller to address a wide variety ofusage. You can configure several products of the same model to participate in a single-phase
three-wire system (48 kVA / 72 kVA / 30 kVA / 36 kVA) or three-phase four-wire system (72 kVA /108 kVA / 45 kVA / 54 kVA) by using a System Cable (optional).
The AC output of DP series and DP series Type R ranges from 0 to 320 V for voltage (phasevoltage) and 1 to 550 Hz for frequency, and the DC voltage output ranges from −454 V to +454 V.
The maximum output current (phase current) is 240 Arms / 360 Arms / 150 Arms / 180 Arms
continuous (100 V range), and if you use a capacitor input type rectified load, you can output a peakvalue of 960 Apk / 1080 Apk / 600 Apk / 720 Apk at a maximum (100 V range, crest factor of 4).
DP series Type R have a reverse power flow capability.
* It is noted that regeneration from the load is described as “reverse power flow” in this manual.
Also, it is noted that DC regeneration is described as “sink current” and DC power running is
described as “source current”.

Features

Reverse power flow
DP series Type R supports the reverse power flow. User does not need to consult with the powercompanies about power system interconnection because DP series Type R processes the reverse
power internally and does not regenerate to the power system when the reverse power flow is
occurring. Also, DP series Type R supports sink current in DC mode. User can use DP series Type R
for testing equipment such as bidirectional converters.
Various interfaces to address a variety of usage
The interface to use for the remote controlling from a computer or sequencer is equipped. USB and
RS232 interface are standard, and either GPIB or LAN (LXI 1.4) interface can be chosen whenordering. You can use a contact/TTL signal to turn the output on/off or switch the memory without
using a computer. The product also offers the status output for showing the device status and theoutput which is synchronized with Sequence or Simulation step. With these functions you canachieve various types of systemization and automatization. The AGC function and Autocal function
for calibrating the output voltage drop are also provided.
Variable current limiter
This function can limit the effective value and the positive/negative peak value of the output current
where the limiting value is variable. You can set the limiter so that the output is turned off when thelimited condition continues for a certain time.
Power input
Either three-phase three-wire input or three-phase four-wire input can be chosen when ordering.
Feature-rich measurement function
RMS/peak/averagevaluesoftheoutputvoltage/current,

current

peak-holdvalues,active/apparent/reactive power, the power factor, the crest factor, and harmonic current are measured
and displayed.

Using Limiter, Setting Limiter4.1.1 Use Peak Current Limiter
Peak value of output current is limited by the peak current limiter. While the limiter is working, icon
is displayed and LIMIT LED illuminates.
Setting values of peak current limiter are variable, and kept independently for each of 100 V and 200
V ranges.
You can choose whether to make the output off or not upon the triggering of the peak current limiter.
If you choose to set the output off, specify the continuous operation time of limiter until the output
off becomes effective. Whether output off is set or not and the time setting are common regardlessof the output ranges.
For the default setting range, see 10.13.
-------- Notes -----------------------------------------------------------------------------------------------------------Output current value may be limited by a value that is different from the setting value,depending on the load.
For an inductive load, overvoltage protection may be triggered due to the operation of peakcurrent limiter. Overvoltage protection may be avoided by lowering the limiter setting value
both for negative and positive values.
When the number of power units that are energized is increased or decreased based on the
power unit energization setting, the setting values of the peak current limiter are reset to thescaled factory default setting in proprption to the number ratio of energized power units. Referto 10.13 for details.
In the polyphase system, the setting of the peak current limiter is common to all phases.
If the output off after the continuous operation of the limiter for the specified duration isenabled, the setting of output-off phase is ignored.
In the case that the peak current limiter operates when the setting value of the peak current
limiter is set as asymmetry between positive and negative in the AC mode, the DC component
is generated in the output. Although the function to remove the DC component of the output
works in the AC mode, when the peak current limiter operates intermittently, the DC
component may not be removed sufficiently, or the output waveform may be modified.

Effective value of output current is limited by the RMS current limiter. While the limiter is working,icon

is displayed and LIMIT LED illuminates.

Setting values of RMS current limiter are variable, and kept independently for each of 100 V and
200 V ranges.
You can choose whether to make the output off or not upon the triggering of the RMS current
limiter. If you choose to set the output off, specify the continuous operation time of limiter until the
output off becomes effective. Whether output off is set or not and the time setting are common
regardless of the output ranges.
For the default setting range, see 10.13.
[DP series Type R only]
While the reverse power flow is occurring, the effective value of output current is not limited.
However, icon

is displayed and the LIMIT LED lights up to notify user when effective valueof output current exceeds the set limit value.
-------- Notes -----------------------------------------------------------------------------------------------------------It will take time from the limiter starts operation until the output current is restricted enough,because the RMS current limiter needs to calculate effective value. Use the peak current
limiter to limit the current quickly. For peak current limiter, see 4.1.1.
When the number of units is increased or decreased based on the power unit energization
setting, the setting values of the RMS current limiter are reset to the scaled factory default
setting in proprption to the number ratio of energized power units. Refer to 10.13 for details.
In the polyphase system, the setting of the RMS current limiter is common to all phases.
If the output off after the continuous operation of the limiter for the specified duration isenabled, the setting of output-off phase is ignored.
[DP series Type R only] While the reverse power flow is occurring, limiting the output current
may cause the output voltage rise and the load damaged, so the output current is not limited.
-----------------------------------------------------------------------------------------------------------------------------CAUTION
For loads with very low impedance (e.g. output short circuit, etc.), the RMS current limitercannot sufficiently limit the output current and may exceed the rated current. Use within the
rated current range by checking the current measured value and using the peak current limiter
together etc.

4. Advanced Operation

4.1.3 Using Voltage Setting Range Limit
For the Continuous function, when the signal source is INT, SYNC, or ADD, the range of the output
voltage setting value to the internal signal source can be limited. Even if trying to set a voltage thatexceeds the limit, the setting value is restricted to the limiting value. This can prevent mis-setting
when you do not want to set values outside the range.
As for the voltage setting range limiting values, each value is kept independently for the following
settings for 100 V and 200 V ranges respectively: SIN/CLP waveform in AC mode, ARB waveformin AC mode, ACDC mode, and DC mode.
In case of polyphase output, the setting of the voltage setting range limit is common to all phases,
and kept as the effective value of the phase voltage in this product. When the line voltage setting(effective value setting) is selected in balanced mode, it is converted into the effective value settingof the phase voltage according to the following formula and kept in this product.
Balanced three-phase output:

Phase voltage =1
3

× Line voltage

Balanced single-phase three-wire output:

Phase voltage =1
× Line voltage
2

The limiting value should be set using the effective value or the positive and negative peak value.
The effective value can be used only when in the AC mode and the waveform is a sine wave or aclipped sine wave. The limiting value can be set using the line voltage in polyphase output when in
AC mode and balanced mode, and the output voltage setting is a line voltage setting. In other cases,
set using the positive and negative peak values of phase voltage.
For the default setting range, see 10.14.
-------- Notes -----------------------------------------------------------------------------------------------------------The voltage setting range limit is useful for the prevention of an excessive output when asetting value is rapidly increased or decreased by using the shuttle.
The limitation is applied to the additional values of the AC voltage setting (recalculated to apeak value) and the DC voltage setting.
The voltage setting range limit cannot be applied to the external signal source of EXT and ADD.
The Sequence and the Simulation function do not include the voltage setting range limiting
function.
The voltage setting range limit that does not include an output voltage already set cannot be set.
In polyphase output, the voltage setting range limit is common to all phases.
In ACDC mode, set the voltage setting range limit setting using the positive and negative peakvalues of the phase voltage regardless of the settings of the waveform, balanced/unbalanced
mode, phase voltage/line voltage.

You can limit the range of the frequency setting value for the internal signal source by using thefrequency setting range limit. Even if trying to set a frequency that exceeds the limit, the setting
value is restricted to the limiting value. This can prevent mis-setting when you do not want to set
values outside the range.
The frequency setting range limiting value is common to both 100 V and 200 V ranges.
For the default setting range, see 10.14.

4.1.5 About Wattage Limiter
The wattage limiter operates when trying to output the power exceeding the rated power. When thewattage limiter operates, the output voltage is suppressed until the active power per phase is thevalue in Table 4-1 (reference value). While the limiter is working, icon

is displayed and

LIMIT LED illuminates.
[DP series Type R only]
While the reverse power flow is occurring, the wattage limiter does not operate. However, icon
is displayed and the LIMIT LED lights to notify user when the output power exceeds thevalue of wattage limiter (see Table 4-1).
When the reverse power flow satisfies one of the following condition, icon

is displayed andthe LIMIT LED flashes.
The reverse power exceeding 40% of the electric power capacity has lasted for 3 minutes.
The reverse power exceeding 40% of the electric power capacity has occupied 20% in duty
cycle.

CAUTION[DP series Type R only] If ambient temperature is 30°C or higher, do not let the reverse power
flow occur while the LIMIT LED flashing.
[DP series Type R only] Output may be shut off to protect the inside of this product if thereverse power flow exceeds specifications. Be aware that shut off in the reverse power flow may
cause voltage rise of the load.

4. Advanced Operation-------- Notes -----------------------------------------------------------------------------------------------------------If the wattage limiter operates, suppress the output wattage within the rated output power bylowering the output voltage setting value.
Active power (unit: W) is restricted by the wattage limiter, however, reactive power (unit: var)
is not restricted. Therefore, the apparent power (unit: VA) may exceed the rated power
depending on the power factor of the load. Set the output voltage so that the apparent power
does not exceed the rated power, regardless of the operation of the wattage limiter.
The value of the wattage limiter cannot be changed. To limit the output power to a value that islower than the rating, decrease the number of power units that are energized through the power
unit energization setting, or use the peak current limiter or the RMS current limiter.
[DP series Type R only] While the reverse power flow is occurring, the output active power is
not limited. If the limiter enabled, it raises output voltage to block the reverse power flow.
Therefore the limiter is disabled in order that the load may not be damaged by the raised
voltage.

Using Sequence Function

4.2.1 Basics
By using Sequence function, an output setting can be changed step-by-step according to the program(sequence) created beforehand. This section describes the basics for using the Sequence function.
AC/DC Mode and Signal Source
Sequence function keeps the selection of the AC/DC mode and a signal source, independently from
Continuous function/Simulation function. AC/DC mode can be selected from AC/ACDC/DC. A
signal source is fixed as INT.
Keep a sequence setting
The sequence setting is kept per AC/DC mode. Every time AC/DC mode is changed, the sequence
setting that is already kept is loaded. The sequence setting is cleared when the power is turned off.
To save the setting, you need to save it in internal memory or USB memory (see 4.9).
Step
One sequence consists of a series of two or more steps. To use Sequence function, first set each step.

4.2 Using Sequence Function

Step-control Parameters and intra-Step Parameters
There are the following two major types of parameters in Sequence function:
Step-control parameter
Parameter to control the flow between two or more steps. This defines duration of each stepand the next step to transition. Settings of step synchronous code and trigger output areincluded in step-control parameter for convenience.
Intra-Step parameter
Parameter to define output state in each step. This defines basic parameters such as a
waveform, frequency, and how they are changed in the step.

Intra-Step parameter

Step No. 0
Step No. 0 is assigned to the stand-by state before the sequence starts. If the terminal specificationof the step other than No. 0 is End, the execution transitions to step No. 0 and enters into thestand-by state. Step Time and the Step Behavior setting of No. 0 specifies the action to transit to No.
0 at the end of a sequence.

4. Advanced Operation

Step Behavior (Const, Keep, Sweep)
For the intra-Step parameter other than waveforms and phases, the following three patterns can be
set as the method to change values in the step.
Constant (Const)
Fixed to the value set in the step.
Keep (Keep)
Keeping the value immediately before transitioning to the step. That is, the value is changed
depending on the status of the previous step. Although the parameter value can be set even if
the operation type setting is Keep, the parameter setting value is ignored when sequence is
executed.
Sweep
It changes linearly from the value immediately before transitioning to the value set in the step,
taking the Step Times. In other words, it reaches the setting value after the Step Time passes inthe step. The starting value is changed depending on the status of the previous step.

The rate of crest factor/clip ratio cannot be changed though a clipped sine wave can be selected
as an output waveform in Sequence function. Set these parameters beforehand using
Continuous function.
Sequence function displays the measured value in Sequence function, which is equivalent tothat of the Continuous function. However, harmonic current measurement (see 4.4) cannot be
displayed.

4.2.2 Parameters of Sequence Function
Table 4-2 shows the parameters of Sequence function. The common parameters are common to one
sequence. In Sequence function, signal source is fixed to INT. In each step, set the step-control
parameter and the intra-Step parameter. As for intra-Step parameter, the item and range that can be
set differ depending on the output range (100 V/200 V range) and output mode
(AC-INT/ACDC-INT/DC-INT) as in the case of Continuous function. This section describes
intra-Step parameters and step-control parameters separately.

Phase angle canalso be set per step. The phase angle of L1 phase cannot be set, and is fixed as 0 deg.
Step Time (Step Time)
Set the output time of that step. Unit can be selected from [s] or [ms].
Jump-to step (Jump To)
When selected, the destination step of the jump at the end of the step can be specified. By specifying
the Jump count ([Jump Cnt]), you can set up a loop to repeat the same step. After jumping for thetimes specified for one sequence, the action at the end of step follows the step termination setting.
If Jump-to is set to off, the action at the end of step follows the step termination setting.
-------- Notes -----------------------------------------------------------------------------------------------------------When the step termination is set as [Hold], the hold status is enabled before the jump.
-----------------------------------------------------------------------------------------------------------------------------

4. Advanced Operation

Jump count (Jump Cnt)
Number of times of jumps to jump to the step specified in Jump-to. This can be set when Jump-to([Jump To]) is selected. When the Jump count is set to 0, infinite times of jumps occur.
-------- Notes -----------------------------------------------------------------------------------------------------------The number of times that a particular step is repeated is Jump count +1.
----------------------------------------------------------------------------------------------------------------------------Branch step (Branch1, Branch2)
When the step is under execution or in the hold state, the step to transition when the branching
instruction through panel operation or CONTROL I/O is detected can be specified. There are twosystems of branch instructions (Branch1 and Branch2), and an instruction can be set for each.
-------- Notes -----------------------------------------------------------------------------------------------------------Transition using branch is executed immediately after a branching instruction is detected. Step
Time, Stop Phase, and step termination setting are ignored.
----------------------------------------------------------------------------------------------------------------------------Step termination (Step Term)
Specifies the action when the step completes. When [Continue] is selected, transitions to the step of
the next number. When [End] is selected, the sequence is terminated and the execution transitions tostep No. 0 and enter into the stand-by state. When [Hold] is selected, the output at the end of the stepis suspended, and the execution transitions to the step of the next number when Resume instruction
is detected.
-------- Notes -----------------------------------------------------------------------------------------------------------When [Step Term] is set to [Hold], the execution enters into hold state before jump. Jumps
when Resume instruction is detected.
When [Step Term] is set to [Hold], after the jumps repeated for the specified Jump count, theexecution transitions to the step of the next number when Resume instruction is detected inhold state.
While in the hold state due to the step termination in a step where step termination phase isenabled, the execution transitions to Jump-to step or the step of next number when Resume
instruction is detected, after the hold state is kept until Stop Phase.
----------------------------------------------------------------------------------------------------------------------------Step sync code output (Code)State output to CONTROL I/O connector. Code to output while the execution of the step, which is
specified by 2-bit H/L.
Start Phase (StartPhs)
Determines the phase of AC waveform of L1 phase when the step starts. The phase when a step
starts in L2 and L3 phase of polyphase system is the addition of the setting value of intra-Stepparameter Phase and the setting value of the step Start Phase.
72

PROGRAMMABLE AC POWER SOURCE

4.2 Using Sequence Function-------- Notes -----------------------------------------------------------------------------------------------------------Step Start Phase setting can be disabled. In that case, the phase when the phase starts becomesthe phase when the previous step ended.
In DC mode, the step Start Phase cannot be set.
----------------------------------------------------------------------------------------------------------------------------Stop Phase (Stop Phs)
Determines the phase of AC waveform when the step ends. The phase when a step ends in L2 and L3
phase of polyphase system is the addition of the setting value of intra-Step parameter Phase and thesetting value of the step Stop Phase. When the stop phase setting is active, the execution waits for
the Step Time that was set pass, and keeps the output setting until it reaches the Stop Phase that wasset, and then transitions to the next step. As the result, the actual step time is longer by one cycle at a
maximum than the set Step Time. Figure 4–3 shows an example where both the Stop Phase of theprevious step and the Start Phase of the next step are set to 0°.

Figure 4-3 Stop Phase-------- Notes -----------------------------------------------------------------------------------------------------------When the Step Behavior is set to [Sweep], output is constant while waiting for the step Stop
Phase after the Step Time passes.
Step Stop Phase setting can be disabled. In this case, when the set Step Time has passed, theexecution transitions to the next step without waiting for step Stop Phase.
In DC mode, the step Stop Phase cannot be set.
----------------------------------------------------------------------------------------------------------------------------Trigger output (Trig Out)
State output to CONTROL I/O connector. This specifies whether the trigger output presents when
the step starts. Polarity and pulse width of the trigger output complies with the trigger output setting(see 4.2.5).

the sequence starts.
In the case that the step termination is set to [Hold] (No. 3), and when the execution is in theHold state, it transitions to step No. 0 and enters into the stand-by state if the Stop operation is
executed. If you perform Resume operation here, the execution transitions to the step of thenext number (No. 4).

Using Power Fluctuation Testing (Simulation) Function

4.3.1 Basics
The Power fluctuation testing (Simulation) function allows you to edit and output voltage patterns
that simulate power line anomalies such as blackout, voltage rise, voltage drop, abrupt phase change,
and abrupt frequency change. This section describes the basics for using the Simulation function.
AC/DC Mode and Signal Source
Simulation function sets the AC/DC mode and a signal source, independently from Continuousfunction/Sequence function. The setting is fixed to ACDC-INT.
Keep simulation setting file
The simulation setting is cleared when the power is turned off. To save the setting, you need to saveit in internal memory or USB memory (see 4.9).

PROGRAMMABLE AC POWER SOURCE

4.3 Using Power Fluctuation Testing (Simulation) Function

Step
The output by the Simulation function consists of six types of steps: Initial, Normal 1, Trans 1,
Abnormal, Trans 2, and Normal 2. Before the simulation starts, the DP240S / DP360S / DP150RS /DP180RS stands by at the Initial Step. During the simulation, the step changes in the order of Initial,
Normal 1, Trans 1, Abnormal, Trans 2, and Normal 2. After the simulation ends, the DP240S /DP360S / DP150RS / DP180RS returns to the Initial Step and stands by.
Step parameter
Each parameter of Step Time, AC voltage, frequency, start phase, stop phase, trigger output, andsynchronization output can be set for each step. However, some parameters cannot be set in somesteps.
Initial Step
Initial Step is assigned to the stand-by state before the simulation starts. The DP240S / DP360S /DP150RS / DP180RS also moves to the Initial Step and becomes stand-by state after the simulation
ends, except when the repeat count is specified to 0 (= infinite count).
Transition Step (Trans 1 and Trans 2)
The Step Times of Trans 1 and Trans 2 can be set to zero for simulating the abrupt voltage andphase changes. When the Step Time is set to the value other than zero, the set voltage and frequency
are swept linearly at the previous and next steps. Note that the AC voltage, frequency, start phase,and Stop Phase cannot be set in the Transition Steps.
Other issues
The Exit operation is available during the simulation. Performing the Exit operation moves tothe Initial Step. The output remains on.
You can set the repeat on/off and repeat count for the simulation. When the repeat is set to on
and the repeat count to zero (0), the testing repeats infinitely.
-------- Notes -----------------------------------------------------------------------------------------------------------The Simulation function does not support the standard tests defined by organizations such as
IEC. Use this function for a preliminary testing.

4.3.2 Simulation Function Parameters
Table 4-4 shows the parameters of Simulation function. The common parameters are common to one
simulation. In the Simulation function, the signal source is fixed to INT sine wave and the ACDC
mode to ACDC mode. When in polyphase, the balanced mode is always used. In each step, set the
step-control parameter and the intra-Step parameter. As for intra-Step parameter, the range that canbe set differ depending on the output range (100 V/200 V range) as in the case of Continuousfunction.

Start phase (Start Phs)
ON or OFF can be selected for the start phase. When ON is selected, the step starts at the specified
start phase. When OFF is selected, the step starts at the phase in which the previous step ended.
When selecting ON, a numerical entry box in which you can specify the start phase opens.
The start phase can be set at the Normal 1, Normal 2, and Abnormal steps. For other steps, the startphase is fixed to OFF and cannot be specified.
Stop phase (Stop Phs)
ON or OFF can be selected for the stop phase. When ON is selected, the step ends at the specified
stop phase. If the phase is not the specified stop phase after the Step Time elapsed, the execution
continues the output of that step until reaching the specified Stop Phase, then performs the next step.
When OFF is selected, the step transitions to the next step when the Step Time has elapsed
regardless of the phase. When selecting ON, a numerical entry box in which you can specify the stop
phase opens.
The stop phase can be set at the Normal 1, Normal 2, and Abnormal steps. For other steps, the stop
phase is fixed to OFF and cannot be specified.
Trigger output (Trig Out)
State output to CONTROL I/O connector. This specifies whether the trigger output presents when
the step starts. Polarity and pulse width of the trigger output complies with the trigger output setting(see 4.3.5). At the Initial Step, the trigger output cannot be specified and thus no trigger is output.
Step sync code output (Code)State output to CONTROL I/O connector. Code to output while the execution of the step, which is
specified by 2-bit H/L. The step synchronization code can be specified also at the Initial Step.

Repeat (Repeat)
You can set to repeat the simulation in a series from the Normal 1 step to the Normal 2 step. Specify
the ON or OFF of repeat and the repeat count. When Repeat is set to ON, the simulation repeats forthe specified count. The simulation in a series is repeated for the repeat count + 1. Setting the repeat
count to zero (0) means an infinite count. When Repeat is set to OFF, the DP240S / DP360S /DP150RS / DP180RS executes the simulation only once and finishes it without performing therepeat operation.

4.4.1 Harmonic current
Some electric devices of AC power input have its input current waveform greatly distorted from thesine wave. When the power input section uses a capacitor input type rectifier circuit, the input
current typically distorts as shown in Figure 4–20. A waveform distorted like this contains many
harmonic components. If a current with many harmonic components is supplied to the power line inhigh volume, the line voltage is distorted, causing problems such as malfunction of devices andoverheated transformer which may result in accidents.

Measuring Inrush Current

4.5.1 Inrush Current
On an electric device using a capacitor input type rectifier circuit for power input, an excessive
current in comparison to the Normal state may flow for a short period of time immediately after thestart of power supply. This current is called inrush current. If such a big current flows to the powerline, the supply voltage may drop due to the impedance of the power line. Therefore, the inrush
current is restricted below a certain level in some standards.
Figure 4–21 shows the inrush current waveform of a small electric drill. The inrush current flows at
14 A peak, which is about four times of the rated current of 3.5 A.

4. Advanced Operation

It is necessary for an electric device with a large inrush current to use a power source with asufficient current supplying capability. With a power source that cannot supply a sufficient inrush
current, some electric devices may not start as they are not supplied with necessary power.
This product has the ability to supply peak current up to four times of the RMS rating. You canmeasure the maximum inrush current value using the current peak-hold function of the product.

4.5.2 Basics
Output current peak-hold function holds either a positive or negative peak value, whichever islarger in absolute value.
Current peak-hold value is displayed in all of the Average, RMS, and Peak measurement viewsin the Normal View.
Clearing function for the current peak-hold value is provided. The clear operation clears thecurrent peak-hold value (all phases) to 0 Apk.
-------- Notes -----------------------------------------------------------------------------------------------------------The peak hold value starts to update again immediately after the clear operation. The clear
operation may not turn the current peak-hold value to 0 Apk even when no current is being
output, because of noise or other reasons.

Read current peak-hold value (Ipk-Hold). This is the maximum inrush current value.

4.5.4 Measurement Tips
You can see the difference among inrush currents at each power-on phase by changing thephase setting at output on (see 3.4.7) before turning on the output.
The object inrush current cannot be measured correctly when the maximum peak current
exceeds the one that can be supplied by this product or the peak current limiter is activated.
Correct peak value measurement may not be accomplished for a very small load impedance,such as when there is a short at the output terminal.

Using Clipped Sine Wave

Clipped sine wave is the waveform that has its sine wave peak clipped as shown in Figure 4–22. This
product can select the clipped sine wave as the output waveform.

Figure 4-22 Clipped Sine Wave

The depth of clip is set using the crest factor or clip ratio. Each of them is defined by the following
expression. The clip ratio is set in percentage.
Crest factor = Peak value/RMS value
Clip ratio = Clipped sine wave peak value/Original sine wave peak value
As shown in Table 4-8, the output voltage setting method differs depending on the clip depth setting
method. Therefore, a clip ratio less than 100% makes the output voltage smaller than the setting.

4.11 Using Remote Sensing Function

4.11

Using Remote Sensing Function

The Remote sensing function detects the output voltage at the sensing input terminal. When the
Remote sensing function is on, the measured value of voltage is the voltage at the sensing input
terminal, and the item symbol is displayed as "SV" on the panel display. The measured values ofpower (P, S, Q) and power factor (PF) are also the values that are calculated using the measured
voltage value at the sensing input terminal. However, their item symbols on the panel display are notchanged.
When the Remote sensing function is on, the output voltage at the sensing input terminal iscalibrated by the AGC or Autocal function. Thus, by combining the Remote sensing function with
the AGC/Autocal function, you can compensate the voltage drop due to wiring to the load.
The Remote sensing function can be set to on in the AC-INT, AC-VCA, AC-SYNC, DC-INT, and
DC-VCA modes. However, for the AC mode, it can be set to on only when the waveform is a sine
wave. When the Remote sensing function is on, the waveform cannot be changed to other than a sine
wave. When the mode is changed to ACDC mode, when the signal source is changed to EXT or
ADD, or when the Sequence or Simulation function is selected, the Remote sensing function is
forcibly set to off.
However, in case the stand-by state of sequence mode (step0) effective only for AC-INT,
ACDC-INT and DC-INT and when the waveform is sine wave or DC. Remote sensing cannot be
activated unless either AC voltage or DC voltage setting is 0 V for ACDC-INT. Also, Remotesensing is turned off once when you change ACDC mode from AC mode of DC mode even instand-by state. Turn ON it again when you need.
-------- Notes -----------------------------------------------------------------------------------------------------------The on/off state of the Remote sensing function is kept even if the output range is changed.
When the Remote sensing function is forcibly set to off, the settings saved in the System
Setting Memory are not updated.

4.12 Using AGC Function

4.12

Using AGC Function

The AGC (Automatic Gain Control) function calculates the ratio (calibration factor) of the output
voltage measured value (effective value) versus the output voltage setting value automatically andcontinuously while this function is on, and multiplies the gain of the output amplifier by thecalculated value, intending to match the output voltage with the setting value. With this function, theoutput voltage fluctuation can be suppressed even when the load is fluctuated. When the AGC
function is set to on, the icon

is displayed.

As the detected part of the output voltage calibrated by the AGC function, either the sensing input
terminal (the Remote sensing function is on) or the output terminal (the Remote sensing function isoff) can be selected. By combining the Remote sensing function with the AGC function, you cancompensate the voltage drop due to wiring to the load.
The AGC function can be set to on in the AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA
modes. However, for the AC mode, it can be set to on only when the waveform is a sine wave.
When the AGC function is on, the waveform cannot be changed to other than a sine wave. When themode is changed to ACDC mode, when the signal source is changed to EXT or ADD, or when the
Sequence or Simulation function is selected, the AGC function is forcibly set to off. When the
Autocal function is on, the AGC function cannot be used.
For the specification of the AGC function, see 10.16.
-------- Notes -----------------------------------------------------------------------------------------------------------If the output voltage setting is out of the "Operation range" shown in 10.16, the calibration is
not performed while the AGC function setting remains on and the icon

is still

displayed.
If the difference is out of the "Calibration range" shown in 10.16, the AGC function is forcibly
set to off, and the icon

disappears.

If the limiter operates while the AGC function is on, the AGC calibration is not performed.
When the limiter operation is completed, the AGC calibration restarts. If the protection
function is activated, the output is turned off, but the AGC setting remains on.
The on/off setting of the AGC function is kept even if the output range is changed.
When the AGC function is forcibly set to off, the settings saved in the System Setting Memory
are not updated.
The AGC function updates the calibration factor continuously while the AGC function is on.
In contrast, the Autocal function continues to use the calibration factor obtained when Autocal
is turned on until Autocal is turned off. Therefore, in the AGC function, the output voltage iscalibrated properly even when the load is fluctuated, but there is the response time to reflect
the update of the calibration factor. Meanwhile, in the Autocal function, the output voltage
may not be calibrated properly when the load is fluctuated, but once Autocal is turned on,
there is no response time needed for calibration.

Therefore, even when the Autocal function is on, theoutput voltage fluctuation may occur if the load is fluctuated. When the Autocal function is set to on,
the iconis displayed.

As the detected part of the output voltage calibrated by the Autocal function, either the sensing input
terminal (the Remote sensing function is on) or the output terminal (the Remote sensing function isoff) can be selected. Combining the Remote sensing function with the Autocal function, you cancompensate the voltage drop due to wiring to the load.
The Autocal function can be set to on in the AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA
modes. However, for the AC mode, it can be set to on only when the waveform is a sine wave.
When the Autocal function is on, the waveform cannot be changed to other than a sine wave. Whenthe mode is changed to ACDC mode, when the signal source is changed to EXT or ADD, or when
the Sequence or Simulation function is selected, the Autocal function is forcibly set to off. When the
AGC function is on, the Autocal function cannot be used.
However, in case the stand-by state of sequence mode (step0) effective only for AC-INT,
ACDC-INT or DC-INT and when the waveform is sine wave or DC. Autocal cannot be activatedunless either AC voltage or DC voltage setting is not 0 V for ACDC-INT. Also, Autocal is turned
off once when you change ACDC mode from AC mode of DC mode even in stand-by state. Turn
ON it again when you need.

PROGRAMMABLE AC POWER SOURCE

4.13 Using Autocal Function-------- Notes -----------------------------------------------------------------------------------------------------------When the Autocal function is on, the calibration factor is always used to perform thecalibration as a multiplier.
If the conditions for setting the [Acal] to [ON] shown in 10.17 are not satisfied, the Autocal
function cannot be turned on. However, if any one of the conditions required for setting [Acal]
to [ON] becomes disabled while the Autocal function is on, the ON setting of the Autocal
function is retained.
If the difference is out of the "Calibration range" shown in 10.17, the Autocal function is
forcibly set to off
If the limiter operates while the Autocal function is on, the Autocal calibration is still applied,but the limit is applied on the output. If the protection function is activated, the output isturned off, but the Autocal setting remains on.
When the output range is changed, the Autocal function is forcibly set to off.
When the Autocal function is forcibly set to off, the settings saved in the System Setting
Memory are not updated.
The Autocal function continues to use the calibration factor obtained when Autocal is turnedon until Autocal is turned off. In contrast, the AGC function updates the calibration factor
continuously while the AGC function is on. Therefore, in the Autocal function, the output
voltage may not be calibrated properly when the load is fluctuated, but once Autocal is turned
on, there is no response time needed for calibration. Meanwhile, in the AGC function, theoutput voltage is calibrated properly even when the load is fluctuated, but there is the responsetime to reflect the update of the calibration factor.

Setting Voltage using External DC Input Signal

In the AC-VCA mode, you can use the external DC input signal to set the AC output voltage of theinternal signal source. In the DC-VCA mode, you can use the external DC input signal to set the DC
output voltage of the internal signal source. The external DC signal is input to this product throughthe external signal input connector. When the signal source is VCA, the specifications except theoutput voltage setting are same as when the signal source is INT.
-------- Notes -----------------------------------------------------------------------------------------------------------For VCA, the external signal input is detected with the interval of about 100 ms.
-----------------------------------------------------------------------------------------------------------------------------

4.17.1 Using External Signal in AC-VCA ModeIn the AC-VCA mode, the peak value of the output AC voltage (ACV) is set according to thefollowing figure, by using the gain setting value and the voltage of the external DC signal.
ACV (Vpk) = Gain x External DC signal voltage (V)For the specifications of the gain setting range and the external DC signal input voltage range, see
10.22.2.
-------- Notes -----------------------------------------------------------------------------------------------------------The gain setting value is retained for each of 100 V/200 V ranges and for each of AC/DC
modes.
Within the same range and the same mode, the same value is retained for the gain setting value,
regardless of the combination of the signal sources (VCA, EXT, ADD).
For the polyphase system, the ACV setting using VCA is common to all phases.
When the switching from AC-VCA mode to ACDC mode, the signal source is forcibly set to
INT.
----------------------------------------------------------------------------------------------------------------------------Examples

Amplifying the External Signal Input

When you select EXT for the signal source, you can output the amplified external signal. Also, when

10.22.3.
-------- Notes -----------------------------------------------------------------------------------------------------------The gain setting value is retained for each of 100 V/200 V ranges.
Within the same range, the same value is retained for the gain setting value, regardless of the
combination of the AC/DC mode and the signal sources (VCA, EXT, ADD).
If the voltage after the external signal is amplified, or if the total voltage of the amplified
external signal and the internal signal exceeds ±227 V (100 V range)/±454 V (200 V range),
the output voltage is clipped at that value.
If the signal source is set to EXT, the calculation is carried out in certain intervals by themeasurement function of this product. Therefore, the measurement operation cycle may
become inappropriate depending on the external signal frequency, resulting in the instablemeasured value display. In that case, set [ADD] for the signal source and configure the settings
as below. When the signal source is set to [ADD], the measurement calculation is performed in
optimum interval for the frequency which is set for the internal signal source. This may solve
the instability of the measured value display.

to reduce the power consumption of this product.
If there is a power unit on which the energization is disabled, the rated power icon is displayed
inverted. For details on the rated power icon, see 3.2.5 and 5.1.1.
You can disable the energization for the power unit that may have a failure while continuing
operation of the product by using the remaining power units. For details, see 8.1.3.

Select [OK]. The energization is enabled or disabled and the window is closed.

-------- Notes -----------------------------------------------------------------------------------------------------------The maximum current, current monitor gain, current measurement full scale, and the power
measurement full scale are set to the values corresponding to the rated output power which isdetermined by the number of power units to be energized. However, the applied current
measurement accuracy and the power measurement accuracy are the values under thecondition where all power units are enabled for energization.
If the number of the energized power units is changed, the setting values of the peak current
limiter and the RMS current limiter are restored to the factory default settings corresponding to
the rated power which is determined by the number of the power units to be energized.
If you select [OK] without changing the energization settings in the power unit energization
setting window, the energization settings of all power units are disabled once and enabledagain. The setting values of the peak current limiter and the RMS current limiter are restored
to the factory default settings corresponding to the rated power which is determined by the
number of the power units to be energized.
For a polyphase system, the number of power units on which the energization is enabled mustbe same on all phases.
If a failure occurs in a power unit for some reason, you can disable the energization for that
unit to restart using this product with the remaining power units. For details, see 8.1.3.

Communication Interface

This product is provided with the USB and RS232 communication interfaces as standard and isremote-controllable by a computer. Also, either GPIB or LAN communication interface can bechosen when ordering. The remote control allows almost all the operations available on the control
panel to be performed. In addition, it can read the internal state such as setting values and errors.
The command language is compliant with the SCPI Specification 1999.0.
Regardless of which communication interface is used, you can create and use a program that uses
the Virtual Instrument Software Architecture (VISA) library. If you do not have a license to use
VISA library, you need to obtain one (generally, it requires some cost).
For details of the remote control commands and programming, see "Instruction Manual (Remote
Control)" in the attached CD-ROM.

6.1.1 USB
The product is compliant with the USB Test and Measurement Class (USBTMC). Normally, theUSBTMC class driver supports the sub class USB488 and can perform almost the same controls as
GPIB on USB.
Preparation
The computer used for control needs a USBTMC class driver installed on it. The USBTMC classdriver is included in the hardware and software product of each company that provides the VISA
library.

8.1 Error Messages and Error Handling

8.1.3 If An Error Occurs Repeatedly
If an error message repeatedly appears even though you removed the cause of the error, the error
may be resolved by restarting the power unit.
If the error still exists, the product or the power unit in the product may be faulty. Repair is neededin this case. Contact the seller (NF Corporation or our agent) from whom you purchased the product.
Even though one of the power units is faulty, the product can be used by disconnecting the faulty
power unit and using the rest of them.
The following shows how to restart and disconnect the power unit in the case of an error.
-------- Notes -----------------------------------------------------------------------------------------------------------The following procedure is available only when the [PU-ON] soft-key is displayed on the error
message window. Stop using the product in the case of a repeating error without the [PU-ON]
soft-key.
----------------------------------------------------------------------------------------------------------------------------Operation procedure1.

In the error message window, press the [PU-ON] soft-key. The power unit energization setting
window opens.

2.

The power unit with an error is marked with "E" like

. Check on the power unit that has anerror. First, leaving the energization setting as is, select OK. All the power units are restarted.
3.

When the error message window is displayed again, press the ENTER key.

4.

If the error still exists, press the [PU-ON] soft-key again to open the power unit energization
setting window.

5.

Check on the power unit that has an error. If the same power unit still has an error, it may be
faulty. Move the cursor to this power unit, then press the ENTER key. The check mark on thispower unit is removed, showing. If a different power unit has an error, leave the check

mark as is. Select [OK].
6.

The power unit energization setting is updated, and only the power units with the check markare restarted. When the error message window is displayed again, press the ENTER key.

7.

Repeat the step 4 and later ones until errors are resolved. After the error is resolved, the productcan be continuously used using the power units with the check mark.

DP240S/DP360S/DP150RS/DP180RS

221

8. Troubleshooting-------- Notes -----------------------------------------------------------------------------------------------------------The E mark does not mean it is faulty but indicates the protection operation was activated. In
some cases such as the protection operation was activated in a chain-reaction manner, the E
mark may appear on a normal power unit. A power unit is judged as faulty by checking
whether the error repeats or not after the power unit is restarted as described in the step 2.
When the error message is "ID:54 Power Unit DCPS Undervoltage" or "ID:52 Power Unit
DCPS Error," the error is quite likely to be resolved after the power unit is restarted as
described in the step 2.
-----------------------------------------------------------------------------------------------------------------------------

8.1.4 Protection Operation Types
When the protection function is activated or an error is detected, the product applies one of thefollowing five types of protection operation and error message, according to the error level.
System Lock
The output turns off. No operations are accepted on the control panel and the remote controller. The
panel says "System Locked." To operate the product again, it is necessary to cycle the power of it.
Output Off
The output turns off. The panel says "Output OFF" and "Press Enter Key." When you press the
ENTER key, you will return to the previous window for further operations if the cause of the error
has been removed. Otherwise, the error message window will be displayed again.
When the [PU-ON] soft-key is displayed on the error message window, pressing the soft-key opens
the power unit energization setting window. If an error repeatedly occurs, you can disable theenergization of the power unit that has the error to continue to use the product with the rest of thepower units. For details, see 8.1.3.
Message display only
The output state remains unchanged. The panel shows the error message window. Press the ENTER
key to return to the previous screen for further operations.
Limiting action
The output is limited. The panel shows the icon indicating the limiting action, without an error
message. In addition, the LIMIT LED illuminates on the front panel. The output turns off after agiven period according to the limiter setting. In this case, an error message appears after the output
off.
Icon display
The output state remains unchanged. The panel shows an icon instead of an error message. The
panel operation is available as usual.

checking firmware version
For the simple operation check, see 2.6.

9.2

Daily Maintenance

The product shall be installed in a location that satisfies the installation conditions (see 2.2).
When the panel or case is dirty
Wipe it with a soft cloth. If the dirt is heavy, wipe it with a cloth wrung out with diluted neutral
detergent solution.

CAUTION
Do not use solvents (thinners, benzine, etc.) or wipes. Otherwise, the surface may be altered or
the coatings may be peeled off.

When the front grill air filters are dirty
A front grill is provided with air filters for removing dust or dirt from the intake air. Clogged air
filters deteriorate the ventilation, resulting in excessive high temperature inside the product. This
may activate the overheat protection, affecting the operation, or damage the internal parts, resulting
in failure. Regularly check the air filters for dirt, about once a month. If air filters are found dirty,
rinse with water to remove the dirt, dry completely, then remount them. You can optionally request
additional air filters for replacement (see 7.3).

CAUTION
Do not install the product in a place with a large amount of extremely fine dust (e.g., powders).
The air filters may not fully work.
Do not install the product in a damp place prone to dew. The air filters are more likely to be
clogged.

WARNING
Before removing the air filters and the front grill, be sure to cut the power to the distribution
board. Otherwise, an electric shock might occur.

The description noted with "/" indicates that the specification changes by the output range, such as"100 V range specification/200 V range specification."
The input voltage is noted as line voltage in three-phase four-wire input, unless otherwise noted.
A value with the accuracy is the guaranteed value of the specification. However, an accuracy noted
as reference value shows the supplemental data for reference when the product is used, and is notunder the guarantee. A value without the accuracy is the nominal value or representative value(shown as typ.).
DP240S/DP360S/DP150RS/DP180RS corresponds to Clause 2 (8) Frequency converter, Appendix 1of Export Trade Control Ordinance. The permission for exportation of the Japanese Administrationis necessary for export outside Japan.
Notes on Polyphase System
Single-phase three-wire (1P3W) system can be configured by connecting 2 models of the same type(output power capacity). Three-phase four-wire (3P4W) system can be configured by connecting 3
models in the same way. These are called as polyphase system.
Firmware discriminates power capacity and polyphase type at the start-up process just after turningon the system connected with an optional system cable (either 1P3W or 3P4W type), and the systemstarts to operate as that power capacity and polyphase type.
Output Lo terminals connected together become a neutral point (N terminal) in both the 1P3W and
3P4W system. Hi terminals are called L1, L2, and L3, respectively (L3 exists only in 3P4W system).
The cabinet to which the L1 connector of the System Cable is connected operates as master. The
cabinets to which L2 and L3 is connected operate as slave. Output voltage is defined with phasevoltage (L1, L2, and L3 to N) in this document unless otherwise noted.

10.13 Current Limiter
This controls the output voltage for the output current to be within the limiter setting value when
the peak value or RMS exceeds it. The output can be configured to be turned off when the limited
state continues over the specified time.
In the polyphase system, the settings are made for the phase current and common to all the phases.
If a user increased or decreased the number of working units by the power unit energization
setting, the setting range and the factory default setting vary in proportional to the ratio of theworking units to all the units (8 units). Refer to the example below. Digits under resolution are

10.15 Remote Sensing
This switches the voltage used for measurement. When the remote sensing is on, the sensing input
terminal voltage is used. When it is off, the output terminal voltage is used.
By combining with AGC or Autocal, a voltage drop due to wiring to the load can be compensated.
When the remote sensing is on, the output voltage detection point corrected by the AGC or
Autocal function is switched to the sensing input terminal. When AGC or Autocal is off, only thedetection voltage used for measurement display is switched.
Effective only for AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA and when the waveform
is sine wave or DC. It is turned off when the Sequence or Simulation is selected.
However, in case the stand-by state of sequence mode (step 0) effective only for AC-INT,
ACDC-INT and DC-INT and when the waveform is sine wave or DC. Remote sensing cannot be
activated unless either AC voltage or DC voltage setting is 0 V for ACDC-INT. Also, remotesensing is turned off once when you change ACDC mode from AC mode of DC mode even instand-by state. Turn ON it again when you need.

When the AGC (Automatic Gain Control) is on, the detection point voltage is always measured,and the output voltage is continuously corrected so that its effective value is equal to the output

the load is fluctuated. The detection point can be switched between the sensing input terminal(remote sensing on) and the output terminal (remote sensing off).
Effective only for AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA and when the waveform

10.17 Autocal (Output Voltage Compensation)
When the Autocal (Automatic Calibration) is on, the detection point voltage is always measured,and the output voltage is continuously corrected so that its effective value is equal to the output
voltage setting value. The ratio (correction factor) of the detection point voltage to the output
voltage setting value is used until the Autocal or the power is turned off. Therefore, the detection
point voltage is not necessarily maintained if the load changes while the Autocal is on. The
detection point can be switched between the sensing input terminal (remote sensing on) and theoutput terminal (remote sensing off).
Unlike the AGC, it cannot follow a load fluctuation because it does not keep track of the voltage.
On the other hand, when the load is stable, it has a merit of short response time on changing theoutput voltage setting.
Effective only for AC-INT, AC-VCA, AC-SYNC, DC-INT, and DC-VCA and when the waveform
is sine wave or DC. It is turned off when the Sequence or Simulation is selected. It cannot be
selected when the AGC is set to on.
However, in case the stand-by state of sequence mode (step 0) effective only for AC-INT,
ACDC-INT and DC-INT and when the waveform is sine wave or DC. Autocal cannot be activatedunless either AC voltage or DC voltage setting is 0 V for ACDC-INT. Also, Autocal is turned off
once when you change ACDC mode from AC mode of DC mode even in stand-by state. Turn ON
it again when you need.

*49: The crest factor is represented as "voltage peak value/voltage effective value." It is 1.41 for sinewave.
*50: When the clip ratio is specified, the peak is clipped by the voltage corresponding to thespecified % to the peak value of the setting voltage (100 %).
Example) For the output voltage setting of 100 Vrms and the clip rate of 80 %, the peak isclipped at 113.1 Vpk.

10.22 External Signal Input
The external signal input works differently depending on the selection of the signal source.

10.22.1 External Synchronous Signal Input (Signal Source SYNC only)This is the signal to synchronize the frequency of the internal signal source with the one of theexternal signal source.
When the signal source is SYNC, you can select whether to synchronize with this external signal
input or the power input frequency of the product. When synchronizing with the power input
frequency, no signal input is needed.

10.22.2 Voltage Setting Signal Input (Signal Source VCA only)This is the signal to set the output voltage amplitude of the internal signal source (DC input).
Output voltage (Vpk) = Voltage setting signal (Vdc) × Gain (Vpk/Vdc)
Example 1)

For the AC mode, signal source = VCA, the gain of 100.0, and the voltage setting
signal input of 1 Vdc, the output voltage is 100 Vpk.

Example 2)

For the AC mode, signal source = VCA, the gain of 141.4, and the voltage setting
signal input of 1 Vdc, the output voltage is 141.4 Vpk (=100 Vrms).

10.22.3 External Signal Input (only EXT and ADD)
This multiplies the input signal by the specified gain and outputs it. For ADD, the internal signal
source is added.
EXT: Output voltage (V) = External signal input (V) × Gain (V/V)
ADD: Output voltage (V) = External signal input (V) × Gain (V/V)+ Internal signal source setting (V)External signal input cannot be used for the polyphase system.
