CCD Intelligent Composite Switch
The CCD Intelligent Composite Switch adopts a hybrid topology combining a thyristor and a magnetic latching relay. It integrates the inrush-free switching capability of thyristors with the low power consumption of mechanical switching, providing a reliable switching solution for low-voltage reactive power compensation systems.
Product Description
During switching, the thyristor performs zero-crossing turn-on and turn-off to eliminate inrush current and arc generation. After switching is completed, the magnetic latching relay maintains the conduction state with low power consumption. With a mechanical service life exceeding 1,000,000 cycles, the CCD supports frequent switching and long-term reliable operation.
