AC power supply PCR-M series
Operation
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 CONTROL 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 OUTPUT outlet.
• If a capacitor, battery, or a similar device is connected 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 possibility of electric shock, do not touch the OUTPUT terminal block and OUTPUT outlet.
CAUTION
When the OUTPUT is turned on, several volts of undershoot or overshoot may appear on the order of ten microseconds.
The PCR-M does not cut off output from the internal circuits 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 chattering. When the OUTPUT is off, the output is in high-impedance condition.

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.
