The RGC1P48AA30E is a 1-pole proportional switching solid state contactor with an integrated heatsink, designed to control the output power of single-phase AC loads. It operates with a rated voltage of 190-550 VAC and handles a rated operational current of 30 AAC at 40°C. Control is managed via a 4-20 mADC analog input, and the device offers selectable operating modes including phase angle and full cycle control. Integrated overvoltage protection is provided by a built-in varistor across the output. This controller is ideal for applications requiring precise power regulation, such as industrial heating and motor control.
