Features
Communication function
RS232C, USB, and LAN interfaces are all installed as standard.
The remote interfaces comply with IEEE Std 488.2 1992
and SCPI Specification 1999.0.
The LAN interface complies with the LXI standard. Multichannel (VMCB), which controls up to 31 PWR-01s from a
single PC, can be used to construct a multichannel power
supply system.
Master-slave parallel operation
You can increase the output current by connecting up to
three PWR-01s (two units for the 1200W model) in parallel.
You can set one unit as the master unit, and control the
remaining units as slave units.
If an error occurs in a slave unit, the master unit detects the
alarm and shuts down the output of the entire system.
Setting preset memory function
You can save up to three sets of output settings (the combination of the voltage, current, OVP, OCP, and UVL). You
can simply select a set of output settings that you want to
use rather than having to specify each setting every time.
Automatic output-on setting
You can set the PWR-01 so that when a low AC input protection function (AC-FAIL) is activated and the output is
turned off, the output is automatically turned back on when
the problem that caused the output to turn off is fixed.
Output-on/off delay function
You can set the delay (DELAY TIME) from when the OUTPUT key is turned on or off to when the output actually turns
on or off. This is useful when you want to turn the output on
or off by setting a delay according to the load characteristics.
Set voltage/current limitation function
You can apply limits to the voltage and current settings. This
prevent you from setting an appropriate value by mistake,
which would cause the output to turn off.
Overcurrent protection (OCP) detection time setting
You can set the amount of time that an overcurrent must
persist after the first detection of the overcurrent before the
overcurrent protection (OCP) is activated. If inrush current
from the load causes an excessive current to flow temporarily, you can adjust the delay to prevent the overcurrent protection (OCP) from being activated.
Bleeder circuit function
You can turn the bleeder circuit on and off. Turn the bleeder
circuit off when you do not want the internal bleeder circuit
to sink output current. When you connect a battery, you can
prevent excessive electrical discharges by turning the
bleeder circuit off.
Soft start/ stop function
You can limit the rise time of the load current for loads that
produce inrush current when the output is turned on.
Varia bl e internal resistance function
You can easily simulate rechargeable batteries, solar batteries, fuel cells, and other power supplies that have internal
resistance. By setting the internal resistance value in constant voltage (CV) mode, you can decrease the output voltage according to the output current.
Sequence function
The sequence function recalls conditions set in a program
and runs automatically. If you write a program created on a
PC into the PWR-01, you can execute the program from the
panel.
When a program is written in the PWR-01, you can execute
the program without a PC.
CONFIG setting shortcut function and display
You can register CONFIG setting parameters to the front
panel’s SC keys. Because you do not have to go into the
CONFIG menu to set the parameters, you can perform tests
efficiently by registering CONFIG parameters that you use
frequently. Up to three parameters can be registered.

CAUTION
Note that the output will become unstable if the following types of loads are connected.
Loads with peak current or pulse-shaped current
The PWR-01 only indicates mean values. Even when the indicated value is less than or equal
to the set constant current, the peak values may exceed the set constant current. If this happens, the PWR-01 is instantaneously put into constant-current mode, and the output voltage
drops.
For these types of loads, you must increase the set constant current or increase the current
capacity.
Load current with peaks Pulse-shaped load current
Loads that generate reverse current to the power supply
The PWR-01 cannot absorb reverse current from the load. Therefore, if a regenerative load
(such as an inverter, converter, or transformer) is connected, the output voltage increases
and becomes unstable. This can cause a malfunction.
For these types of loads, connect a resistor (RD) as shown in the following figure to bypass
the reverse current. However, the amount of current to the load decreases by Irp.

CAUTION
Loads with accumulated energy
Connecting a load with accumulated energy, such as a battery, to the PWR-01 may cause
current to flow from the load to the internal circuit of the PWR-01. This current may damage
the PWR-01 or reduce the life of the load.
For this type of load, connect a reverse-current-prevention diode (DRP) between the PWR-01
and the load in series as shown in the following figure.
This cannot be used in conjunction with remote sensing.
• To protect the load and the PWR-01, use a DRP that conforms to the following
specifications.
Reverse voltage withstand capacity: At least twice the rated output voltage of the PWR-01.
Forward current capacity: 3 to 10 times the rated output current of the PWR-01.

Selecting the Load Cables
WARNING
CAUTION
Risk of fire.
• Use load cables whose capacity is adequate for the PWR-01’s rated output current.
• The output terminal and its surrounding area become very hot. Use cables whose
covers have an allowable temperature of 85 °C or higher.
Risk of electric shock.
• Use load cables with a voltage rating that meets or exceeds the product’s isolation
voltage. For details on the PWR-01’s isolation voltage, see Chap.7 "Specifications"(p.117).
• Use load cables with a core diameter that is appropriate for the amount of current being
used and with sturdy, flame-resistant insulation.
Current capacity of load cables
A cable’s temperature is determined by the resistive loss based on the current, the ambient
temperature, and the cable’s external thermal resistance. The following table shows the current capacity of heat-resistant vinyl cables that have a maximum allowable temperature of
60 °C when one of the cables is separated and stretched out horizontally in air in an ambient
temperature of 30 °C. The current must be reduced under certain conditions, such as when
vinyl cables that have a low heat resistance are used, when the ambient temperature is 30 °C
or greater, or when cables are bundled together and little heat is radiated.

Taking measures against noise
When connecting cables that have the same heat resistance, separating the cables as much
as possible to increase heat radiation enables a greater amount of current to flow. However,
wiring the + (positive) and - (negative) output wires of the load cable side by side or bundling
them together is more effective against unwanted noise. The Kikusui-recommended currents
shown in the above table are allowable currents that have been reduced in consideration of
the potential bundling of load cables. Use these values as a guideline when connecting
cables.

Installation and Preparation ｜ Selecting the Load Cables
Limitations of the remote sensing function
All wires have resistance. As the wire becomes longer or the current becomes larger, the voltage drop in the wire becomes greater. This results in a smaller voltage being applied at the
load end. The PWR-01 has a sensing function that compensates for this voltage drop up to
the following values (p.30). If the voltage drop exceeds this level, use cables that have a
greater cross-sectional area.

Risk of electric shock. For safety reasons, even if the output terminal is grounded,
make sure that the insulation capacity of the output terminal (including the sensing
terminal) is greater than or equal to the isolation voltage of this product.
For details on the isolation voltage of each model, see "Specifications" (p.117).
If you cannot obtain a cable with sufficient rated voltage, secure adequate withstand
voltage by passing the cable through an insulation tube with a withstand voltage
greater than the isolation voltage of the PWR-01.
The signal cable may burn out. If the PWR-01 is to be controlled through an external voltage
(Vext), do not ground the external voltage (leave it floating).
The cable and load that are connected to the output terminal (including the sensing terminal)
must have an insulation capacity that is greater than or equal to the isolation voltage of the
PWR-01 with respect to the chassis. Isolation voltage indicates the maximum allowed voltage
that appears across the output terminal of the power supply unit and the protective conductor
terminal (chassis terminal).
When the output terminal is not grounded (floating)
The output terminal of the PWR-01 is isolated from the protective conductor terminal. If you
connect the GND wire of the power cord to the ground terminal of the switchboard, the chassis of the PWR-01 is set to ground potential.
The J1 connector on the rear panel are at approximately the same electric potential as the
PWR-01’s negative output terminal. Cables and devices that are connected to these pins
must have an insulation capacity greater than or equal to the isolation voltage of the PWR-01.

All pins of the J1 connector are

When the output terminal is grounded
If the positive output terminal is connected to the chassis terminal, the positive output terminal is at ground potential. The cable and load that are connected to the output terminal
(including the sensing terminal) will only require an insulation capacity that is greater than or
equal to the maximum output voltage of the PWR-01 with respect to the chassis.
The same holds true when the negative terminal is connected to the chassis terminal. The
cable and load require an insulation capacity that is greater than or equal to the maximum
output voltage of the PWR-01.
For safety reasons, connect one of the output terminals to the chassis terminal unless your
application requires the output terminals to be floating.

Turning on the POWER switch
Risk of electric shock. Regardless of whether load cables are connected to the output
terminals, be sure to attach the OUTPUT terminal cover before turning the POWER
switch on.
Risk of damage to load.
If the PWR-01 is configured to turn on the output when the POWER switch is turned on in
CONFIG settings, set an appropriate OVP or OCP value before connecting a different load.
If the POWER switch is turned on for the first time after purchase, the PWR-01 starts in the
factory default condition (p.136). Subsequent times that you turn the PWR-01 on, it starts with
the panel settings (excluding the output on/off setting) that were in use immediately before
the POWER switch was turned off.
You can use the CONFIG settings (CF45) to select the output state of the PWR-01 when the
POWER switch is turned on (p.65).
Check that the power cord is connected correctly.

All the indicators light, and then the voltmeter and the ammeter display the following
sequence of information: the rated voltage and rated current, the firmware version

After a few seconds, the PWR-01 enters the operation standby state (the measured
value is displayed).

Installation and Preparation ｜ Turning the Power On
CAUTION
Turning the POWER switch off
Turn the POWER switch off ( ).
The PWR-01 saves the panel settings (except the output on/off setting) that were in use
immediately before the POWER switch was turned off.
You can use the CONFIG settings (CF45) to select the output state of the PWR-01 when the
POWER switch is turned on (p.65).
If the POWER switch is turned off immediately after the settings have been changed, the last
settings may not be stored.
After you turn the POWER switch off, wait at least 10 seconds after the panel display turns
off before you turn the POWER switch back on. Repeatedly turning the POWER switch on
and off at short intervals can cause damage to the inrush current limiter. Furthermore, this
will shorten the service life of the POWER switch and the internal input fuse.

Remote Sensing function
E3-200-546
WARNING
Remote sensing is a function that stabilizes the output voltage across the load by reducing
the influence of voltage drops and other effects caused by the load cable resistance.
The PWR-01 remote sensing can compensate up to the values shown below. Select a load
cable that has sufficient current capacity to prevent the voltage drop in the load cable from
exceeding the compensation voltage.
When you perform remote sensing, set the voltage of the sensing point (across the load) so
that it does not exceed the rated output voltage. If you are performing remote sensing with
the voltage close to the maximum output voltage, the output is limited by the maximum output
voltage (105 % of the rated output voltage). Electrolytic capacitors may be required at the
sensing point (across the load).
To reduce the effect of noise, use twisted-pair cables or 2-core shielded cables. When you
use shielded cables, connect the shield to the PWR-01 or the load grounding terminal.

Risk of electric shock and damage to internal circuits.
• Never wire the sensing terminals while the POWER switch is turned on.
• For sensing cables, use cables with a voltage rating that is higher than the PWR-01’s

insulation tubes whose withstand voltage is greater than the PWR-01’ isolation voltage.
• Even if you turn the out put off or turn the POWER switch off, if the bleeder circuit is
set to off (CF01: DIS), the voltage that was present when the output was on will
remain at the output terminals. Set the bleeder circuit to on (CF01: NORM/ HYP)
before you touch the sensing terminals.
• Be sure to attach the OUTPUT terminal cover before turning the POWER switch on.
