VT series switching controller


Product feature
VT series reactive power compensation Thyristor switching controller is a kind of electric power component to fast switch LV capacitor groups. It’s convenient for installation, connection and maintenance; No inrush current, no over voltage happens during switching; No noise happens during working, and allow frequent action.
