Introduction
STS series thyristor switching regulator is an electronic power unit capable of rapidly switching parallel capacitors. Its main circuit of the regulator adopts an anti-parallel thyristor module, and the other electronic components form trigger circuit, synchronization circuit and control circuit. Its control circuit and the control signal of the controller are optically isolated to avoid interference. When the controller sends a switching signal, the thyristor turns on or off, thus putting or cutting off the corresponding capacitor. It is suitable for rapid input and rapid removal of 0.4kV low voltage capacitors.
