BYFK Series intelligent low-voltage composite switch

BYFK composite switch is a combination of inteligent chips, digital circuits, and magnetic holding relays to achieve voltage zero crossing conduction and current zero crossing cutoff, allowing the switch to fully switch to zero crossing at the moment of turning on and off, without generating overvoltage. Switches have many advantages such as no inrush current, extremely low power consumption, high lifespan, and low fault rate, and are widely used in the field of low-voltage reactive power compensation.
