Celduc SG4 Series Solid State Relay, 40 A Load, Panel Mount, 460 V rms Load, 10 V dc Control

Phase Angle and Frequency Burst Regulators. SG5 relays with proportional control have an analogue input isolated from the mains allowing a proportional variation of the operating duty cycle at this input through the generation of frequency bursts. Applications: heating regulation.- Ve = 0 V → t/T = 0% - Ve = 5 V → t/T = 50% - Ve = 10 V → t/T = 100%. The SG4 models have an analogue input isolated from the mains allowing a proportional variation at this input of the switching instant on the sine wave. Applications: motor speed variation, dimmable lighting. Specific documentation available on request.
