Thyristor Switch / Reactive Power Regulator
AZS series thyristor switches (reactive power regulators) for fast switching of power capacitors, available in TSC and RTSC types.
Overview
The AZS series regulator is a power device for fast switching of power capacitors. It mainly consists of bidirectional thyristors, trigger circuits, snubber circuits, temperature protection switches, heat sinks and cooling devices. The regulator has no inrush current during switching, good conduction performance and fast response. It includes a built-in over-temperature protection switch and a switch for automatic fan control, supporting safe and stable long-term operation. It is suitable for frequent switching of dynamic compensation and harmonic treatment capacitors.
