Self-returning protector

A self-repeating over- and under-voltage product is a device used to protect electrical equipment from over- and under-voltage.It monitors the voltage condition of the power grid and once it detects that the voltage is out of the set range, it automatically cuts off the power supply, thus protecting the equipment from damage.Such products usually have an automatic reset function, once the voltage returns to normal, it will automatically resume power supply without manual intervention.In addition, some self-repeating over- and under-voltage products also have a time-delay protection function, which can delay for a period of time before resuming power supply, in order to avoid frequent switching on and off of the equipment.Self-replicating over- and under-voltage products are widely used in a variety of electrical equipment and systems, such as air conditioners, refrigerators, computers and other household appliances, as well as industrial equipment, medical equipment and other fields.They can effectively protect the equipment from voltage fluctuations, extend the service life of the equipment, and improve the reliability and stability of the equipment.
