The maximum value of the output current (peakvalue) will be provided consecutively to acapacitor input-type rectifying load when thefollowing situations exist:
Output voltage is 100 to 200 V within the 100 V
range.
Output voltage is 200 to 400 V within the 200 V
range.
Output frequency is 40 to 999.9 Hz in AC mode,and 1 to 999.9 Hz in AC+DC mode.

Note

Power Factor(PF)

Rated maximum current (rms value) x 6 is equal
to maximum peak current

The power factor, which stands for a ratio of theactive power correlated to the apparent power,
indicates degradation level within efficiency that
results from the phase difference between AC
current and AC voltage.
Equation:17

Crest Factor(CF)

The crest factor stands for a ratio of the rms
value correlated to the peak value (crest value)of the waveform.
Equation:

The crest factor is 1.41 of sine wave.
Note
Inrush Current
Capacity

It indicates the current, which is able to besupplied to a load, exceeds the rating for a shortperiod and the duration.

Output PowerRatio

It indicates the output power of a percentage
where the rated maximum output power is100%.

1-3-2. Alarms
The ASR series have a number of protection features. When one ofthe protection alarms is tripped, the ALM icon on the display will be
lit and the type of alarm that has been tripped will be shown on thedisplay. When an alarm has been tripped the output will be
automatically turned off. For details on how to clear an alarm or to
set the protection modes, please see page 201.

1-3-3. Considerations
The following situations should be taken into consideration whenusing the power supply.
Inrush Current

Capacitive Load

When the power supply switch is first turned on,
an inrush current is generated. Ensure there isenough power available for the power supply
when first turned on, especially if a number ofunits are turned on at the same time.
When the power supply connects to acapacitive load, e.g., capacitor, the load isbeing charged consecutively and the larger thevoltage change, the more the current grow.
Also, the overshoot will be possibly generated
within the currents output, therefore leading to
output turned off thanks to overcurrent
protection from the power supply.
It is suggested to lower down the set voltage
output from power supply so that the voltage ofcapacitive load decreases per certain unit time.
In addition, a block diode is necessary to keep
current from flowing back to the output terminalof power supply. Refer to the figure below
where a block diode connects with thecapacitive load in series to efficiently prevent
current from flowing back to the power supply.
ASR-2000

Block Diode

L
Capacitive LoadN

21

Inductive Load

When the power supply connects to an inductive
load, e.g., inductor, which generates a backEMF (Electromotive Force) when output current
is accidentally turned off, a backflow diode isnecessary for absorbing the back EMF, which
may cause irreversible damage to the power
supply. Refer to the following figure where abackflow diode connects with the inductive loadin parallel to effectively absorb the possible backEMF.

1-3-4. Grounding
The output terminals of the ASR series are isolated with respect tothe protective grounding terminal. The insulation capacity of theload, the load cables and other connected devices must be taken
into consideration when connected to the protective ground orwhen floating.
Grounded
Neutral Output! WARNING

Basically, grounded return on the neutral output
is allowed for ASR series and electric shock
may occur if not following the grounding
procedure based on the local electrical safety
codes. In some cases, 0 V is specificallyrequired between ground and neutral, which
can substantially moderate ground loops, thus
keeping sensitive equipment from effects ofground loops and reducing ground noise.

The maximum temperature rise can only be 60 degrees above
the ambient temperature. The ambient temperature must be lessthan 30 degrees.
To minimize noise pickup or radiation, the load wires and remotesense wires should be twisted-pairs of the shortest possible
length. Shielding of the sense leads may be necessary in highnoise environments. Where shielding is used, connect the shield
to the chassis via the rear panel ground screw. Even if noise is
not a concern, the load and remote sense wires should be
twisted-pairs to reduce coupling, which might impact the stabilityof the power supply. The sense leads should be separated fromthe power leads.

Local Sense
Operation

When using local sense, the remote sensing
input terminal is not used. No compensation of
any possible voltage drop seen on the load
cables is performed. Local sense is only
recommended when the voltage drop is of noconsequence. By default, the power supply is
configured for local sense.
Check that the remote sense setting is disabled(page 120).

85

Remote Sense
Remote Sense
Operation

Remote sense is used to compensate for thevoltage drop seen across load cables due toresistance inherent in the load cables. The
remote sense function can compensate amaximum of 5% of the output voltage and all of
output frequency.
1. Configure the remote sense setting to ON(page 120).
2. Connect the Neutral terminal of the remotesense terminal block to the Neutral terminal of
the load.

Parameter
Overview

The Sequence function is comprised of aminimum of 2 steps that are executed in user
defined sequences.
Each step can have different step time, voltage
level, start & stop phase, frequency and wave.
Note: Step 0 is assigned as a “Standby” step. At
the end of the test the unit will shift to thestandby step.
Step

Assigns the step number.

Time

Sets the step duration time. This
step time is exclusive of any
transition time needed to match
start phases and stop phase. See
the diagram on page 143 fordetails.

ACV

Sets the AC voltage level. Thereare 3 secondary voltage settings
that determine how the voltage is
output.
CT: Sets the voltage level of thestep immediately to ACV values.
KP: Sets the voltage level to“keep” the voltage of the previous
step.
SP: Linearly increases ordecreases the values from theend of the previous step to theend of the current step.
Note: it is available for AC+DCINT and AC-INT modes only.

140

DCV

Sets the DC voltage level. Thereare 3 secondary voltage settings
that determine how the voltage is
output.
CT: Sets the voltage level of thestep immediately to DCV values.
KP: Sets the voltage level to“keep” the voltage of the previous
step.
SP: Linearly increases ordecreases the values from theend of the previous step to theend of the current step.
Note: it is available for AC+DCINT and DC-INT modes only.

AC/DC Voltage
Range(ACV/DCV)

There are 2 voltage range
settings: HI 200V & LO 100V,
which result in varied ranges of
ACV and DCV values,
respectively.

Fset(Frequency)

Sets the frequency of the step.
There are 3 secondary frequency
settings that determine how thefrequency is output.
CT: Sets the frequency level ofthe step immediately to Fset
values.
KP: Sets the frequency level to“keep” the frequency of theprevious step.
SP: Linearly increases ordecreases the frequency from theend of the previous step to theend of the current step.
Note: it is available for AC+DCINT and AC-INT modes only.

141

Wave

Sets the outputting waveform of
the step. Up to 4 waves including
sine, square, triangle andarbitrary (1-16) wave shapes areavailable.
Note: it is available for AC+DCINT and AC-INT modes only.

Jump To

The Jump To setting determines
which step to jump to at the endof the step. If Jump To is turnedoff, the unit will follow the Term
(Step termination) setting for thestep.

Jump Cnt

Determines the number of times
to loop the jump step.

Branch1/
Branch2

The Branch settings allow you tomake a selectable branch within
the sequence when the sequence
is running or on hold. The
branch1 or branch2 actions areenabled by pressing the F1 or F2
function keys, or by using
the :TRIG:SEQ:SEL:EXEC
remote control command. Afterthe branch step(s) havecompleted the unit will returnback to the step from which thebranch was executed andcontinue to run the step from
where it left off.

142

Term
(Termination)

Determines the step termination
settings at end of the step.
The CONTI setting tells thesequence to go to the next step.
The HOLD setting will pause theoutput at the end of the step andwill only continue to the next stepwhen CONTI [F3] is pressed.
The END setting will end thesequence and go to Step0(standby step).

Sync CodeSets the synchronous code
including LL, LH, HL and HH foreach step.

ON/OFF Phs

Sets the start and stop phase of
the AC waveform for each step.
The ON Phs setting sets thestarting phase of the step.
OFF Phs sets the off phase forthe output when the output if
turned off.

8. FAQ
The accuracy does not match the specification.
Make sure the device is powered On for at least 30 minutes, within+18°C~+28°C. This is necessary to stabilize the unit to match thespecification.
For AC output, the voltage will be lower than the voltage setting.
The slew rate mode setting affects the output of AC voltage. In
slope mode, the output voltage drops due to the set waveform andfrequency. If you need a more accurate voltage output, set to timemode. See page 122 for details.
Is it proper to combine 2 or 3 units to reach the 1P3W or 3P4W
output?
Not available. ASR doesn’t support 1P3W or 3P4W output function.
Only support 1P2W output type.

For more information, contact your local dealer or us.
