The voltage of the power grid suddenly became too high. When the voltage is too low or struck by lightning, various types of electrical appliances will be damaged. Once this product is used, all kinds of electrical appliances can be protected from damage, ensuring safety. This product has a delay function. Overvoltage, undervoltage, lightning protection and other protection functions. It has extremely low power consumption, low overall temperature rise, and can operate reliably for a long time. Even if a 110V protector is mistakenly plugged into a 220V power supply, it will not cause damage to the protector. Therefore, this protector is applicable to a wide range of fields.

   Connect this machine to the power supply and electrical appliances respectively. Once the voltage is unstable (190V, less than 260V), this machine will automatically cut off the power supply, monitor the voltage stability, and then restore the power supply.
