SD-TSC thyristor switching switch

The thyristor switch is composed of high-power anti-parallel thyristor module, isolation circuit, trigger circuit, protection circuit, heat dissipation device and other components. It can be used for on-off control of capacitive or inductive loads below 690V. There is no inrush current, no overvoltage, no noise during operation, frequent switching is allowed, installation and wiring are simple and convenient, and it is especially suitable for TSC type dynamic low-voltage reactive power compensation device with fast switching. It is characterized by simple installation, convenient maintenance, fast response speed, no inrush in switching, no noise in operation, stable and reliable, lack of phase and over-temperature protection.
