Anti-voltage dip device Voltage Sag Protector short interruption protection relay Low-voltage circuit anti-shake electric for Semiconductor Industry


As an important control component of the motor circuit, the AC contactor plays an important role in industrial production. The phenomenon of voltage sag caused by lightning strike, short-circuit re-closing, power grid failure, high-power equipment startup and other reasons seriously affects the normal operation of the contactor, and causes the related interlocking equipment to shut down, thus causing huge economic losses to the enterprise. Acrel ARD-KHD-S03 series voltage sag protector has the function of " Contactor hold + restart", which can effectively resist the release of the contactor caused by the shock of the contactor control circuit, guarantee the continuous operation of equipment, and escort the efficient production of enterprises.
