Compact AC Power Supply PCR-MA Series

Versatile output modes

In addition to “AC mode” and “DC mode”, an AC+DC external analog interface board option (EX08-PCR-MA) allows for output control via “EXT-AC mode” and “EXT-DC mode” through external analog signals.

Output Mode: Description

AC mode: AC output

DC mode: DC output

AC+DC mode: Superimpose DC voltage on the AC voltage and output *1

EXT-AC mode: Output sine waves using external DC signals*2

EXT-DC mode: Simply amplify and output the waveform applied externally *2

*1 Only communication commands

*2 Only when the analog interface board (EX08-PCR-MA) is installed.

AC mode

The PCR-MA output voltage range can be set in two ranges (0-155V, 0-310V) with a programmable frequency up to 500 Hz in order to comply with nominal, single phase voltage anywhere in the world. This is especially useful for power supply systems found in aircraft, boats, and actuators.

Settable Voltage Range: Frequency Setting Range

155V range: 310V range

0.0V to 157.5V: 0.0V to 315.0V: 40Hz to 500Hz

DC mode

The output voltage can be varied from ±0V to 219V or ±0V to 438V

Output Voltage Setting

155V range: 310V range

-222.5V to +222.5V: -445V to +445V

AC+DC mode

The output voltage can be varied from ±0V to 219V or ±0V to 438V

Output Voltage Setting

155V range: 310V range

-222.5V to +222.5 V: -445V to +445V

* AC + DC mode is a function used to superimpose DC voltage on AC voltage or AC voltage on DC voltage. It can only be used with the communication commands.

Versatile measurement capability

THE PCR-MA is capable of measuring the voltage, current and power of AC and DC output. It can also display the true RMS and average (DC) values of the output voltage as well as the true RMS, peak, and average (DC) values for the output current. When used with digital interface, the PCR-MA can also measure apparent power (VA), reactive power (VAR), power factor (PF), and peak hold current.

Sensing function (ON/OFF)

The new remote sensing feature compensates for voltage drops along long load wires to ensure maximum accuracy.

Output-on phase angle

The output-on phase angle can be set in AC mode. The output-off phase angle is turned off at the zero-crossing phase.

Memory function

The PCR-MA can store up to three sets of output voltage, frequency, and limit value setting via front panel. Additionally, when using communication commands, the internal memory can store up to 11 settings.

EXT-AC mode

The output AC voltage value can be varied according to the input DC signal.

Maximum peak current

Maximum peak current of up to three times the rated maximum current (rms value) can be output to a capacitor-input rectifier load. Maximum peak current = rated maximum current (rms) × 3.

Protection features

The following protection features are available:

Protection against non-rated input voltage

Protection against overheating (OHP)

Protection against overloading: Current limit (OCP)/monitoring for exceeded power (OPP)/Monitoring for exceeded peak current (OCPP)

Detection of voltage abnormalities:Increased voltage (OVP)/decreased voltage (LVP)

Abnormal sensing cable connection detection (SF)

EXT-DC mode

Amplifies the waveforms that it receives and outputs the result.
