Celduc Relais Solid State Relays SVTA4651E

The SVTA4651E is a three-phase phase angle controller designed for precise voltage control of resistive, inductive, motor, and rectified loads. It features a compact housing measuring 100 mm × 78 mm × 56.5 mm and is mounted with a built-in heatsink. The device supports mains voltages from 200 to 480 VAC at frequencies between 40 and 65 Hz, with a maximum continuous current of 50 A for resistive loads and 12 A for motor loads when used with a heatsink. It offers analog control via a 0-5 VDC input, soft start and stop functions, and full optoisolation for balanced current delivery and reduced harmonics. Diagnostic status indicates load supply and fault conditions through built-in LED and relay outputs. The controller provides 4 kV insulation between inputs, outputs, and case, and operates within an ambient temperature range of -40°C to +90°C.
