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.
