Celduc Relais Solid State Relays SO465320

The SO465320 is a phase angle controller for resistive loads, operating from 200 to 480 VAC at up to 50 A RMS. It features a potentiometric analog input with 8 to 30 V DC supply, and includes an integrated varistor for overvoltage protection. The device complies with EN60947-4-3, EN60950, and VDE0805 standards, and provides reinforced insulation with 4000 V RMS isolation between input and output. It has an IP20 protection rating, a thermal resistance of 0.45 K/W from junction to case, and requires mounting on a heatsink. Operating temperature range is -40 to +90 °C, with storage from -40 to +125 °C. The unit weighs 65 g and uses removable spring connectors for both control and power wiring.
