The Crydom MCPC series of Proportional
Controllers incorporate a complete phase-fired
logic system and Solid State Relay in one small
industry standard package. The MCPC uses
microprocessor controlled logic, accepts a wide
range input logic power supply, provides an
output load status indicator, and five modes of
analog control input along with an Enable/Disable
control.

The MCPC does not require any calibration
adjustment, is optically isolated to 4000Vrms,
includes an internal snubber network, and is
available in load ratings up to 90A and 530Vac.
The Crydom MCPC series is particularly suited to
applications such as tungsten lamp dimming,
vibratory feeders, universal motor control, and
resistive heating element control.
