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 factory 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.

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.

  • *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.

0.0V to 157.5V0.0V to 315.0V40Hz to 500Hz
 

DC mode

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

* 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.
Memory function

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.

EXT-AC mode

The output AC voltage value can be varied according to the input DC signal.
Voltage amplification rate : 15.5 times or 31 times

EXT-DC mode

Amplifies the waveforms that it receives and outputs the result.
Voltage amplification rate : 100 times or 200 times

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)
