Celduc Relais Solid State Relays SVTA4694E

The SVTA4694E is a three-phase digital phase angle controller designed for precise voltage control of resistive, inductive, motor, and rectified loads via 3- or 4-wire configurations. It is housed in a compact 100x78x56.5 mm enclosure, mounted vertically with a heatsink, and weighs 500 g. It operates across 200 to 480 VAC at 40 to 65 Hz, with a maximum AC51 current rating of 50 A (125 A with heatsink) and AC53a current of 30 A. The controller supports 4-20 mA analog input for proportional control, features soft-start and soft-stop functions, and includes built-in overvoltage protection with 510 V varistors. Full galvanic isolation is provided with 4 kV input/output insulation and 2.5 kV status output insulation. It complies with AC51 and AC53a contact ratings and operates at ambient temperatures from -40 to +90 °C.
