BP46101.1

General1.1 General
The BP4610 is a bipolar power supply that combines a high-speed power amplifier capable of bipolar
output of an output voltage and current, and an internal signal source (DC and AC). It can be used as ahigh-speed bipolar amplifier that uses an external signal as input.
Since the BP4610 performs bipolar output, the output voltage and current supply ranges cover all four
quadrants. Whereas only positive current (source current) can be supplied in the case of a general DC
power supply, the BP4610 is capable of supplying both positive and negative (source and sink) current.
Both CV and CC output characteristics are supported, and the rated output voltage and current are 60
V and 10 A, respectively. The output voltage expansion function allows the output of a voltage of up to
120 Vp-p max. in the range of 115 V to +115 V.
The BP4610 has a response calibration function that allows the user to adjust the response
characteristics of the amplifier according to the actual load that is used. As a result, output waveform
distortion can be improved for a wide range of load conditions, including resistance load, capacitive
load and inductive load. Using this function, it is also possible to raise the frequency band for the
resistance load.
The functions (except response calibration adjustment) of the BP4610 can be remotely controlled froman external computer via the USB interface.
100 V AC to 230 V AC can be used as the power supply input, and the consumption current can be
minimized by using the input power factor control function.

1.2 Features
 Large LCD screen operation panel
A large LCD screen operation panel with backlight is provided.

 CV/CC output characteristics
The output characteristics can be selected from between CV (constant voltage) and CC (constantcurrent).
CV characteristics: The voltage is supplied to the load proportionally to the input signal.
CC characteristics: The current is supplied to the load proportionally to the input signal.

 Various signal sources
When using an internal signal source, it is possible to output the AC component (sine wave, squarewave, arbitrary wave) on top of the DC component.
When using an external signal input, it is possible to add the external signal and internal signal
sources.

1-2

BP46101.2

Features Sequence function
When using an internal signal source, the output parameters (output voltage, current, output
frequency) can be sequentially changed or swept, and by programming output changes beforehand,
outputs with specific patterns can be supplied.

 Vo limiter, Io limiter function
The maximum values of the output voltage (Vo) and output current (Io) can be independently set foreach polarity. The output voltage and current are limited to these values.

 Output voltage range expansion function
The output voltage amplitude range can be set to symmetric or asymmetric with regard to thepolarity. Using the Vo limiter function, the output voltage range can be set to a maximum of 120
Vp-p including 0 V within the range of 115 V to +115 V. For example, the output voltage range canbe set to the ranges of 60 V to +60 V, 5 V to +115V, or 115 V to +5 V. Since the suppliable
output current range changes according to the output voltage range setting, the optimum setting
range can be selected from the required voltage and current.

 Response calibration function
The amplifier response characteristics can be selected between fixed characteristics and user
adjusted characteristics. Fixed characteristics are characteristics that emphasize both broadfrequency band characteristics and load stability (during CV, DC to 35 kHz, 3 dB, during CC, DC
to 8 kHz, 3 dB). In the case of user adjusted characteristics, the response characteristics actually
adjusted by the user according to the load conditions can be used. Adjustments of the output voltage
and current waveform are performed by moving three adjustment knobs on the internal part of theoperation panel for the time constant, voltage feedback amount, and current feedback amount, while
watching an oscilloscope.

 Output voltage and output current signal monitor output
The monitor ratio for the voltage is 1/100th of the output voltage, and the monitor ratio for thecurrent is 1 V/10 A, both in phase.

 Measuring function
This function is used to measure and display the output voltage and current (DC value and P-P value
for each).

 Output on/off function
During output on/off switching, the output level (output voltage during CV, output current duringCC) is lowered to 0 and then output relay opening/closing is performed to minimize contact arc.

 USB interface provided as standard
External control can be performed from a PC, etc., via the USB interface.

 Support of worldwide power supply inputs
The power supply input can be switched from 90 V to 250 V.
The consumption current can be minimized with the PFC (input power factor control) function.

Principle of Operation

The BP4610 is composed of the four major blocks.
<1> DC power supply block
The DC power supply block has a variable DC voltage function that works in conjunction withthe power factor improvement function and voltage limiter value. Various control power
supplies and positive/negative DC power supplies for the amplifier block can be created while
improving the power factor for the power supply input. The output voltage range shift function
Refer to “4.4.1 Shifting the output
is enabled by the variable DC voltage function. (voltage range”.)<2> Signal sources
This is an internal signal source that enables the sequence function and DC+AC output. An
external input and internal signal can be used added together.
<3> Amplifier block
The amplifier block has a response calibration function and a protection circuit function. It
outputs signals from an internal signal source or external signal source after amplifying them.
Two types can be selected from among response characteristics, fixed characteristics, and user
adjusted characteristics (response calibration function). If user adjusted characteristics is
selected, the response characteristics can be adjusted according to the load conditions. (Refer to “4.10 Response Calibration”.)<4> System control block
This block is in charge of the user interface, etc.

 Setting value and actual output
Since the output of the BP4610 is influenced by the frequency characteristics of the amplification
block, a difference occurs between the amplitude setting value and the actual output amplitude in thecase of a high frequency.
Figure 4-9 shows the relationship (representative example) between the setting values on theoperation panel and the actual output values.

To protect the load, the BP4610 has output voltage and output current limiter functions implemented
through hardware.
The maximum values for the output voltage and output current can each be set independently for thenegative and positive range. Limiting the output voltage and current to the set values is effective forpreventing failure of the connected load.
Limiter setting values are separately stored in the CV and CC modes.

Sequence Operation

4.5 Sequence Operation
4.5.1 Sequence operation specifications
The BP4610 allows the output voltage and output current to be freely programmed using the sequencefunction.
In addition to basic oscillation, the sequence function can be used as the signal source of the power
supply for specification testing, such as power supply environment testing and automotive electronics
testing. For example, by programming in advance a series of voltage change patterns for use in voltage
variation testing for electrical equipment, the output can be cycled through variations according to apreset sequence, allowing testing to be completed through a single operation.
The BP4610’s internal DC (direct current), sine wave, square wave, or any of 16 arbitrary waveforms
loaded via the USB interface can be used for the sequence operation. The sequence can be set to up to
255 steps (1 step = 0.1 ms minimum), and the waveform, level, duration, and constant/sweep settings
can be selected individually for each step. Moreover, repetition of the sequence can be specified
between 1 to 999 times (or continuous).
Additional functions including branch operation, which causes the operation to go to the specified stepduring sequence operation, sequence start, stop, and hold, are also provided.

 Sequence
A sequence consists of two or more steps, with the minimum unit constituting one step. The
superimposed AC phase is continuous as steps change.

 Step
Step execution and step transition parameters are described for each step. Even in the status where
no sequence is being executed, in other words regular output, the same parameters as for steps areheld. These parameters are subsequently used as regular output steps. In the following description,
step parameters are enclosed in [ ].
The step execution parameters specify the output and its behavior.

The following settings are provided for specifying the step to be transitioned at the end of a[Jump step]step.
 Go to any step number (1 to 255)
 Go to next step number (0)A loop is realized by jumping the specified number of times to the step specified
with[Jump step].

[Jump count]

The following settings are provided for specifying the jump count.
 Specified count (1 to 999)
 Infinite count (0)The following settings are provided for specifying the step to be transitioned to through[Branch step]

 Go to any step number (1 to 255)
 Continue step processing as is (0)When start control is performed in the regular output status when the status is Idle, Step 1 is executedand the steps cycle in the set order.
If [Jump step] is not specified, the steps are executed in the step number order, but if [Jump step] is
specified, that step is transitioned to.
The step end is when the [Step time] has elapsed. If [Step end phase] is enabled, the step end is when
[Step end phase] (0 deg) occurs following the lapse of the [Step time].
If both [Step termination] and [Jump step] are specified, the [Step termination] specification has
precedence.

Though the DC voltage of step 2 is set to 7.50 V, the output DC voltage will be 2.5 V which is
succeeded from the previous step (step 1) because the DC operation type of step 2 is set to KEEP. After
executing step 4, the sequence will jump to step 2 because the jump step of step 4 is set to 2 (<1> inFigure 4-20). The output DC voltage will be kept to 5 V coming from the previous step (step 4) because
the DC operation type of step 2 is set to KEEP. The jump times of step 4 is set to 1, so the sequence will
move to the next step (= step 5) after jumping once and executing step 4 (<2> in Figure 4-20). The steptime of step 5 is set to 0.2 s and the branch 0 jump step of step 5 is set to step 6, so the sequence will

Response Calibration

4.10 Response Calibration
4.10.1 Outline
The BP4610 has a response calibration function that allows individual optimization of transient
response characteristics during square wave output or sudden output changes.
The transient response varies with the load for loads that have complex impedance characteristics suchas electromagnetic parts that include inductance (coil components) or capacitance (capacitor
components). The BP4610 allows the user to adjust the response characteristics according to the load.
The response characteristics of the amplifier can be selected from the following two types.
 Fixed characteristics
 Adjusted characteristics
Switch between fixed and adjusted characteristics in the output off status. Switching in the output on
status is not possible.

4.10.3 Adjustment characteristics
The user can adjust the response characteristics for the load to be actually used.
Through adjustment, it is possible to minimize distortion of the output waveform for a broad range ofload conditions including the resistance load as well as inductive load and capacitive load. Adjustment
to lower speed and higher speed compared to fixed characteristics is possible.
Adjustment is performed by moving three adjustment knobs located towards the rear of the operation
panel, corresponding to the time constant, voltage feedback amount, and current feedback amount,
while observing the output voltage and output current waveform with an external oscilloscope. The loop
characteristics of the amplifier can be changed with these three adjustment knobs, and the output
impedance characteristics changed by an equivalent amount. As a result, distortion of output waveform
can be minimized for a broad range of load conditions.

 Operation procedure<1> Switch off the output.
<2> To be able to observe the output voltage waveform and output current waveform, connect anexternal oscilloscope and the voltage/current monitor terminals (MONITOR OUT) with a

CAUTION

The response characteristics can be improved using the adjustment knobs, but an unstable status(oscillation status) may also result depending on how the adjustment is performed according to theload conditions (including no-load).

Therefore, when using adjustment characteristics, make sure thatthe adjustment knobs are set to their slowest and most stable settings on the left (counterclockwise)
before using an external oscilloscope for waveform monitoring and before adjustment.

4.10.4 Adjustment example
Generally, the capacitive load in the CV mode and the inductive load in the CC mode each form aresonance circuit combined with the output impedance, resulting in a status in which oscillations areeasily generated.
Adjustment examples for the CV mode/capacitive load and CC mode/inductive load are presented
below.
(1)

CV mode/capacitive load
Basically, both T and V are adjusted with their respective adjustment knobs.
While turning the I adjustment knob toward the right lowers the ringing frequency, making iteasier to suppress ringing with the V adjustment knob, normally the BP4610 is used with the I
adjustment knob turned all the way toward the left.
The operations when each adjustment knob is turned are described below.
 If T adjustment knob is turned to the right
The rise/fall become faster, but the ringing frequency also rises, and its amplitude increases.
 If V adjustment knob is turned to the right
The ringing amplitude is decreased, but the rise/fall become slower.
To make the rise/fall as fast as possible and suppressing ringing, perform adjustments by repeating
the following operation.
<1> Speed up the rise/fall with the T adjustment knob.
<2> Suppress ringing when it occurs with the V adjustment knob.

Table 4-24 shows adjustment examples for the three adjustment knobs, and Figures 4-23 to 4-25 show
output voltage waveform examples for each case.

data blocks.
 During reception of program messages by the BP4610, no distinction is made between uppercase
and lowercase.
 Response messages are in uppercase.
 When transmitting multiple program messages in succession, insert a “;” (semicolon) as adelimiter between program messages. A space can also be inserted before and after each semicolonfor even greater reading ease.
 Insert one or more spaces between the header and parameters of set program messages.

 Input buffer Program messages can be sent in batch up to the input buffer capacity (10,000 characters).
 The transmitted program messages are stored in the input buffer and are then interpreted andexecuted in the order in which they have been saved.
 If, during interpreting and execution, an illegal program message is discovered, the execution ofthis and subsequent program messages stops.
 When interpreting and execution are completed, the input buffer is cleared and the next program
messages can be input.

5.6 Programming Cautions
 Arbitrary waveform data
The arbitrary waveform data is the binary data part, and therefore must be transmitted separatelyfrom the command part of the preceding ASCII program message. The arbitrary waveform data mustbe transferred as 1024 words (2048 bytes). If a different amount of data is transferred, an error will

Cleaning the Air Filters

7.5 Cleaning the Air Filters
Dust and dirt that penetrates in the BP4610 and adheres inside may absorb the water content in the
air and therefore cause rusting of metal parts, as well as cause a degradation in insulation
performance leading to the failure of internal high-voltage parts.
Therefore, air filters (which number 6) are provided to eliminate dust and dirt contained in the
inflowing air at the air intake vent on the front panel.
The dirt adhering to the filters, if not removed, will clog up the filters and reduce the air flow,
causing the temperature inside the BP4610 to rise and lowering its reliability.
In such cases, remove the filter and clean out the dirt, as shown below.

When rinsing with water, besure to dry the filter thoroughly before reattaching it.

Air Filter Cleaning Procedure

Filter performance is not fail-proof as filter reliability can be degraded by extremely fine dirt (finepowder) and clogging. Therefore, installation of the BP4610 in a location filled with dust or dirt(including fine powder) or a location with high humidity where condensation can easily occur,should be avoided as much as possible.

8.19 Output Voltage and Output Current Supply Ranges
The supply range differs depending on the positive and negative output voltage limiter settings (+Vo
limit, Vo limit).
The DC output range figures (Figures 8-2 to 8-5) show the relationship between the ouputtable
voltage and current for DC. These figures also show the outputtable ranges for the voltage andcurrent including DC offset for AC of 500 Hz and lower.
The AC output range figures (Figures 8-6 to 8-9) show the relationship between the outputtable DC
voltage and peak current. However, the maximum time interval during which the peak current can be
output is 4 ms.
All values in these figures are for reference only.
