When the mains voltage exceeds the set overvoltage operating voltage of the protector or is lower than the undervoltage operating voltage of the protector, the protector can quickly and reliably break the circuit, thereby protecting the safety of the appliance and our safety. And if the fault voltage of the line has reached the maximum, the protector will not be affected at this time, and will not be damaged.
If the voltage is running normally, the protector at this time can automatically delay the power supply and restore the power supply. All functions are automatically implemented. Do not operate this process manually. There is a light-emitting diode on the panel that shows what the protector works like. The green light of the indicator light is the working power indicator. When the red light is off, the power supply is normal. When the red light is on, the protection function starts to cut off the power supply.
