Intelligent Composite Switch

CDSK Seris Intelligent Composite Switch

CDSK series intelligent composite switch is a special switching component for low-voltage reactive power compensation capacitor banks. It combines the advantages of thyristor and mechanical contactor, realizing zero-crossing switching of capacitors.

Features of zero switching surge, no inrush current and long service life. It can effectively protect capacitors and extend their service life. Matched perfectly with JKL/JKW/JKGPJ PFC controllers and BKMJ capacitors, it is the core matching part of compensation cabinets.

This product adopts advanced electronic circuit design, with reliable action and strong anti-interference. CE certified, suitable for 50/60Hz, 380/400V industrial power grids overseas.
