SSR Mount Phase Angle Control Module, Volts, mA Input, Pot


SSR Mount Burst Fire Control Module, Volts, mA Input, Pot


The MCC-1P is a phase angle control module designed for use with standard footprint random fire SSRs (Solid State Relays).  The module mounts directly on the SSR's input screws.  The module operates by varying the firing point of the SSR's input.  The power delivered to the load is proportional to the command input signal.  The MCC-1P series will not operate correctly with zero cross fired SSRs.


  • Provides true linear power output phase angle control

  • Small (1.75" x 1.40") module mounts on the input terminals of an inexpensive SSR

  • Command input accepts 4-20mA, 0-10V, 0-5V, 0-135Ω, Pot, PWM

  • Configurable line voltage compensation increases stability of your process

  • Configurable soft start for high inrush loads

  • Automatic 50/60Hz operation

  • Adjustable Voltage Limit (-VL) Option

  • Drives multiple solid state relays

  • Single phase and three phase control
