Automatic reset over and under voltage protector​

    Automatic reset overvoltage and undervoltage protector：It is a product that combines overvoltage, undervoltage, phase loss, and zero loss protection functions. It uses a microcontroller to collect voltage and specify the operating voltage range. When the voltage exceeds the standard operating voltage, the protector quickly cuts off the power supply to prevent damage to household appliances. The protection process of the product is fully automatic, with overvoltage and undervoltage automatically cutting off the power supply, and normal voltage automatically closing the circuit
