The RGC3P60V30EDP is a 3-phase proportional switching solid state controller designed to regulate the output power of 3-phase loads. It operates with a rated operational current of 30A at 40°C and a rated operational voltage up to 660VAC. This model utilizes phase angle switching mode controlled by a DC voltage input (0-5V, 1-5V, or 0-10V) and requires an external 24VAC/DC supply. Key features include integrated over-temperature protection (OTP) and mains loss detection, both signaled via an electromechanical relay (EMR) alarm output. This controller is ideal for applications requiring smooth power regulation, such as controlling short wave infrared heaters and other resistive loads.
