Features

• 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.
