SCR switch
Product description
The TSC contactless thyristor switch is composed of the high power reverse parallel thyristor module, the photoelectric isolation circuit, the trigger circuit, the protection circuit, the heat dissipation device and so on. It is used for controlling the switching on and switching off of the capacitive load in the low voltage 400V system. There is no impact inrush current, no overvoltage, no noise during the operation. For this device, frequent switching will be allowed and the installation and wiring is simple and convenient. it is especially suitable for used together with the quick switching SVC low voltage dynamic reactive power compensation capacitor cabinet.
1: With the equipotential zero-crossing technology, it is possible to carry out switching on at the time when of the voltage zero-crossing and perform the switching off when the current is zero. This ensures that there will be no rush current at the time of switching on and there will be no overvoltage when the switching off is performed..
2: The silicon controlled module with high power and high withstand voltage (the reverse voltage resistance is 1600V) is used, which can work stably and reliably after many years of practical project operation.
3:The mature and stable anti interference circuit design will absolutely guarantee the stable operation of the switch for a long term.
4: The contactless thyristor switch has a long service life and is a maintenance free product, with a switching on and switching off time less than 25 Ms.
