Celduc Relais Solid State Relays SO469020

The SO469020 is a phase angle controller for resistive loads, operating from 200 to 480 VAC and rated for 125 A RMS. It accepts a 0-10 V analog control signal and is powered by 8-30 VDC, with an integrated varistor for overvoltage protection. The device is designed for automatic adaptation to mains frequencies between 40 and 70 Hz, features IP20 protection with spring terminals, and must be mounted on a heatsink. It complies with EN60947-4-3, EN60950, and VDE0805 standards, with 4000 V RMS input-to-output isolation. The body is made of PA6 with a nickel-plated aluminum baseplate, weighs 65 g, and operates in temperatures from -40 °C to +90 °C.
