Abstract
A power control system includes a base having a housing configured for releasably receiving a control unit and a cavity within the housing for receiving a solid state relay having a hockey puck configuration. The base includes an input power terminal for coupling to an input power source, an output power terminal for coupling to a power receiving load, and coupling fixtures for fixedly and electrically coupling to input and output power terminals and control terminals of the received solid state relay. A control unit is configured to control the solid state relay for selectively providing, at least a portion of, the power received at the input power terminal to the output power terminal. The control unit has a housing adapted to be releasably coupled to the base housing. The control unit and base each configured to electrically couple the control unit to the control terminals of the received solid state relay as a function of the control unit being coupled to the base.
