The RGC2P60AA40C1 is a 3-phase proportional switching controller designed to regulate the output power of 3-phase loads. This 2-pole controller operates on a rated voltage of 180-660 VAC and handles a rated current of 40 AAC per pole at an ambient temperature of 40°C. It utilizes a single full cycle (C1) switching mode, proportionally controlled by a 4-20 mA DC analog input signal for fast and accurate load management. The device includes an integrated heatsink, built-in varistor protection across each pole, and monitoring for mains loss and internal faults. Its precise control and integrated features make it suitable for applications like industrial ovens, thermoformers, and air handling units.
