Wof composite switch

Wof low voltage intelligent composite switch is a kind of intelligent and energy-saving capacitor switch, which aims at the defects of SCR and AC contactor in the application of low voltage reactive power compensation. The single-chip microcomputer is used to control the switching, and the silicon controlled rectifier is monitored intelligently. The relay, input power and load have perfect functions of abnormal voltage protection, phase loss protection, component fault protection, etc.

The low-voltage intelligent composite switch combines the advantages of SCR and AC contactor:

At the moment of switching, it has the advantages of zero crossing switching of thyristor. During normal switching, it has no power consumption and no burning contact of contactor. No harmonic injection and other advantages. High efficiency, low consumption, energy conservation and environmental protection, is the ideal product for switching capacitors in low-voltage reactive power compensation.
