Installation and Preparation
Connecting the Load
The maximum current that the PCR-M Series can generate
varies depending on the model. It also varies depending on
the PCR-M Series’ output mode, load type, and status. En-
sure that the output power capacity is sufficient for the load
capacity. The maximum output currents (in AC mode - AC
rms, with an output voltage of 1 V to 100 V or 2 V to 200 V,
and with a load power factor of 0.8 to 1) for the different
models are shown in the table.

The values vary depending on conditions such as the wire
covering (insulator), the wire material (allowable tempera-
ture), and whether there are multiple cores in the cable. For
cables other than those specified in this table, consult with
a qualified engineer.
WARNING
Risk of electric shock.
• Use load cables whose capacity is adequate for the
PCR-M series' rated output current.
• Use load cables with a voltage rating that meets or
exceeds the PCR-M series’ isolation voltage (380
Vdc).
• Before you connect cables to the OUTPUT terminal
block, be sure to turn the POWER switch off, and
then remove the power plug from the outlet or turn
off the switchboard.
- Note -
The L and N terminals of the OUTPUT terminal block are
isolated from the input power supply. The polarity does not
constitute a problem in terms of safety. You can use either
L or N to ground the product.
In DC mode and AC+DC mode, N is the reference. When
N has a positive polarity, L is positive electric potential.
When N has a negative polarity, L is negative electric po-
tential.
When the POWER switch is on, even if the output is off, a
dangerous voltage exists between the output terminal (L
or N) and the chassis (G-ground). To eliminate the voltage
between the output terminal and the chassis, connect N
and G of the OUTPUT terminal block.

Operation
Setting the Voltage
You can set the voltage regardless of whether the OUTPUT
is on or off.
If the voltage range is set to AUTO, the range automatically
switches to 135 V or 270 V range according to the specified
voltage. When the voltage range switches, the OUTPUT is
turned off for approximately 0.5 seconds. After the voltage
range switches, the OUTPUT is turned on again.
The factory default voltage lower limit of DC mode is 0.0 V.
You must change the limit to set a negative electric poten-
tial.
In AC+DC mode, the voltage can be specified only when
the AC and DC voltage settings are within the voltage limit
range and the peak value of the AC+DC waveform is within
the range of -388 V to 388 V.

Operation
Turning the OUTPUT On/Off
The OUTPUT turns on/off each time the OUTPUT key is
pressed.
• OUTPUT on
The LED above on the left of the OUTPUT key illuminates.
The voltage and frequency according to the specified
output mode and voltage range are output.
• OUTPUT off
The LED above on the left of the OUTPUT key turns off.
The OUTPUT is always off when the POWER switch is
turned on.
If a protection function trips, the OUTPUT is turned off.
However, if the current limit operation is set to LIMIT CON-
TROL and the overload protection function (current limit)
trips, the OUTPUT is not turned off.
WARNING
Possible electric shock
• Do not touch the OUTPUT terminal block and OUT-
PUT outlet.
• If a capacitor, battery, or a similar device is con-
nected as a load in DC mode, voltage remains at the
section connected to the OUTPUT terminal block or
OUTPUT outlet even when the OUTPUT is off until
the load energy is discharged. The discharge time
of the internal capacitor when no load is connected
is approximately 0.1 seconds. To prevent the pos-
sibility of electric shock, do not touch the OUTPUT
terminal block and OUTPUT outlet.
CAUTION
When the OUTPUT is turned on, several volts of under-
shoot or overshoot may appear on the order of ten micro-
seconds.
■
■Principle of OUTPUT on/off
The PCR-M does not cut off output from the internal cir-
cuits mechanically using switches and relays, but rather
increases output impedance electrically to turn the output
off. Therefore, the output can be turned on/off without chat-
tering. When the OUTPUT is off, the output is in high-imped-
ance condition.

■OUTPUT on phase angle
The OUTPUT on phase can be set in AC mode.
The control of the OUTPUT on phase angle is specified in
the configuration. Because the output capacitor inside the
PCR-M is discharged when there is no load, OUTPUT turns
off at the zero-crossing phase.
