PCR-M Series

Compact AC Power Supplies (CV/CF) : 4 Models


The PCR-M Series is a small-size AC power supply with the ease of a variable auto transformer or an automatic voltage regulator (AVR) and the usefulness of a multifunctional AC power supply. As the PWM inverter method is adopted for the power unit, the PCR-M Series is much smaller and lighter than the predecessors while enabling high-quality and highly-efficient (about 70%) operation. This power supply comes with measurement functions, memory function, protection functions and various communication interface options, and it is even possible to provide DC power. When you incorporate an optional analog interface board (EXO4-PCR-M), the PCR-M Series can also be used as a booster for arbitrary signal generator. This small and versatile unit can provide you with more work styles than you can imagine. You can’t do without it once you use it!


  • Compact design
    Small enough to fit on your work desk !
    Only 214W X 124H X 350D mm !
    Weights only 6 kg and easy to carry !
  • Versatile output modes
    Three modes (AC, DC, AC+DC) are available. *1
    The frequency range is up to 500 Hz.
  • Memory function
    You can store and recall three combinations of settings for voltage and frequency on the main unit. By calling the memory during output, you can test the sudden changes of voltage or frequency.*2
  • Measurement functions
    You can measure the voltage, current and power of AC and DC output, apparent power, reactive power, power factor, crest facter and current peak hold.*3
  • Various communication interface options
    RS-232C is provided as standard. GPIB and USB are optional.
  • Analog interface
    By incorporating an optional analog interface (EXO4-PCR-M), output can be controlled by using external analog signals. Input DC signals can be used to change output AC voltage and boost input waveform.
  • Control using a PC
    You can control the PCR-M Series through the standard RS-232C interface, the optional GPIB interface, or the optional USB interface. And by using the control software (Easy Controller for PCR-M) which comes with the PCR-M Series , you can easily set the parameters of the PCR-M Series and log the output measured values.

    Easy Controller for PCR-M

*1 You can access AC+DC mode if you have installed an optional interface board of IB21, US21 or EX04-PCR-M. The communications interface is used to set that mode.
*2 An installed appropriate optional interface board allows up to ten combinations of settings to be stored in the memory. The communications interface is also used to set or call extended memory addresses (4 to 10).
*3 You can use the communications interface to measure apparent power (VA), reactive power (VAR), power factor (PF), crest factor (CF), and held current peak.
