Thyristors power controller S3-20DR

three-phaseDIN rail

The Power Products range of S3 thyristor power controllers are designed for the control of resistive loads in electric furnaces, and heater batteries in HVAC systems. The S3 power controller series uses zero crossover switching. Burst Pulse Control ensures the load is switched only in multiples of a complete mains half-cycle in order to keep supply and electrical disturbance to a minimum. The units also feature variable frequency PWM for near infinite resolution.
