Product Overview

KS/FK capacitor switching switch is to parallelize the high voltage withstand and high current thyristor with the contact of magnetic holding relay, and automatically find the best switching point and the best switching point through microcomputer control, so as to achieve zero crossing voltage switching on and current switching off. The switching is completed by the thyristor at the moment of switching on and off, and the running current is completed by the magnetic holding relay triggered by pulse voltage to make the contact close.

KS/FK capacitor switching switch has the advantages of non impact, low power consumption, long life, etc. It can replace contactor or thyristor switch and is widely used in low-voltage reactive power compensation field.
