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

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.
