Compact AC Power SupplyPCR-MA Series
Wide-range, programable output voltage up to 310 Vrms with a user friendly interface designed for maximum practicality and convenience.
The PCR-MA AC power supply series is a PWM inverter type (switching) power supply that builds on the success of our conventional model, the PCR-M. Maximum output voltage has been increased to 310 Vrms AC while maintaining a compact, portable design. The digital interface now includes LAN (LXI) and USB as standard, with GPIB as a option for easy integration into any test system. The LXI compliant LAN interface allows the operator to easily monitor and control the instrument via virtual interface wherever they are. Various features including a remote sensing function have been introduced to ensure precise voltage and current measurements. Other features including DC mode, memory functions, and various protections make the PCR-MA the most accessible AC power supply on the market.
Features
Compact design
Small enough to fit on your work desk! Only 214W × 124H × 350D mm! Weighs only 6.5kg and easy to carry!(PCR500MA)
Versatile output modes
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.
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)

Application examples
AC power supply for standby power measurement.
The PCR-MA can be used alongside the KPM1000 Digital Power Meter to conduct measurements compliant with IEC62301, 1st edition. You can also measure the “standby and off mode power” of household and office electronic equipment as required by standards such as Erp Directive Lot 6.
AC power supply for harmonic current measurement.
When used with the KHA1000 Harmonic/Flicker Analyzer, the PCR-MA can be used to conduct harmonic measurements of power supplies compliant with IEC61000-3-2.
AC power supply for capacitator testing.
Combined with the Contact Checker, the PCR-MA can allow you to detect current flowing throw the capacitor, and verify whether it has been connected or not.
