Crydom PMP Proportional Controllers

Crydom's PMP Series are fully configurable Panel Mount proportional control relays with micro controller based technology designed to provide control of the power delivered to single-phase loads of up to 90 Amps at 90 to 600VAC.

PMP Series SSRs vary the output power in proportion to an analog control input, which can be one of 3 signal types: 0-5VDC, 0-10VDC or 4-20mA. The output can be controlled by 2 different methods, selectable on the unit: Phase Angle Control, and Burst Fire Control (with Distributive Zero Cross).

PMP Series proportional controllers are ideal for a wide range of applications that require control of the load power, such as for example lamp dimming and resistive heating control.

  • Output ratings of 25, 50 and 90 Amps
  • Available in 3 operating voltage ranges: 90-280, 345-530 and 420-660VAC
  • Selectable Operation Mode: Phase Angle or Burst Fire control
  • Selectable Control Input: 0-5VDC, 0-10VDC, 4-20mA
  • 50/60Hz Adaptive Operational Frequency function
  • 4-20mA input does not require an auxiliary power supply
  • LED multifunction status indicator
  • Contactor configuration with "Elevator" screw terminals
  • Optional overvoltage protection (built-in TVS diode)
