Refer to the User Manual for technical details on Controller Cards.

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.
