Capacitor switch

overview

The CRFK series capacitor switching switch uses a high-speed 32-bit CPU to precisely control the closing and opening of the capacitor specific magnetic holding relay. Realize the capacitor's zero crossing voltage input, zero crossing current cut-off, no inrush current input, and no arcing cut-off. The magnetic holding relay has the advantage of zero power consumption during normal connection, and the overall power consumption is extremely low. The starting power consumption is less than 10% of the same capacity AC contactor, making it an ideal device to replace AC contactors.


Functional Features

☆ Equipped with a DC negative 12V voltage signal control interface


☆ Equipped with automatic networking function with dedicated 32 loop controller


☆ Protection functions such as phase loss protection, automatic disconnection and closure of contacts during power outages, etc


☆ Automatically adapt to reverse phase sequence


☆ Direct indication of power, switching, alarm and other status LEDs


☆ The control terminal provides 2 common signal connection points, making it convenient for multiple switches to be connected in cascade
