Crydom Solid State Relays (SSRs) are utilized in the lighting industry in a wide range of applications. Beside the obvious on-off supply control, or for the remote power switching points for centralized automated control, Crydom SSRs find widespread use in high power dimming systems for theatrical, industrial and residential applications, as well as airport lighting controls, parking lot lighting, safety lights and energy saving systems for commercial and industrial lighting.

The Crydom MCPC series of microprocessor based proportional controller/SSR modules significantly reduce the amount of design effort and components required to incorporate phase angle dimming control in lighting systems while improving reliability and life.
