First, the product overview

Our company's H-type dynamic switching switch is a kind of “zero-crossing trigger” thyristor switch. It has no inrush current when it is put into the capacitor. The dynamic response time is ≤20ms. It is a power electronic switch for capacitor switching. The main circuit adopts an anti-parallel thyristor module. The control circuit is composed of triggering, photoelectric isolation and logic control. The regulator combines a radiator, a fan, a temperature control, etc., and has an over-temperature protection function in the form of a temperature-controlled startup fan.
