Self-resetting over/under voltage protectors are automatic control devices used to monitor line voltage and ensure the safety of electrical equipment. When abnormal conditions such as overvoltage or undervoltage occur in the power supply line, this product can quickly cut off the power supply to protect downstream electrical equipment; after the voltage returns to normal, it can automatically restore power supply after a delay, without manual intervention, effectively improving the convenience and safety of electricity use.
