The control circuit adopts high-speed micro-low-power processor as the core, magnetic holding relay as the main circuit and analog-digital standard design. When the power supply line has over-voltage and under-voltage, the protector can cut off quickly and safely under continuous high-voltage impact. The circuit prevents the abnormal voltage from being sent into the terminal electrical appliance and causes an accident. When the voltage returns to the normal value, the protector will automatically turn on the circuit within the specified time to ensure that the terminal electrical appliance operates normally under unattended conditions.
