Surge Protector Automatic Voltage Current Protection Socket, Adjustable Overvoltage/Undervoltage Current Limiting Voltmeter AC220V 16A (Dual Standard Display)

1. 【Adjustable Protection Settings】 You can adjust the overvoltage and undervoltage protection values of the voltage protector socket according to the actual needs of your appliance. Overvoltage protection: 230-300V adjustable (standard: 270V), undervoltage protection: 140-210V adjustable (standard: 170V). 2. 【Easy Installation】 The automatic voltage protection socket features a plug-and-play design, making it convenient and quick to use. It can be directly installed on the refrigerator to protect the electrical system from overvoltage, undervoltage, and other power surges. The protector can also be used as a standard outlet for everyday electrical connections. 3. 【LED Display Screen】 The overvoltage and undervoltage protector has an LCD screen. You can clearly and intuitively understand the operating status of the appliance on the LCD screen, update it in real time, and easily operate the buttons. If the voltage is inaccurate, you can adjust the large protective plug between -20V and 20V. 4. 【Intelligent Protection Function】 The voltage protection socket is equipped with a 16A magnetic relay, which can withstand the impact of high current. When there is an overvoltage or undervoltage fault in the circuit, it can instantly cut off the power supply and protect electrical equipment from damage. 5. 【Widely Used】 Equipped with a safety guard to prevent the insertion of fingers or small objects and the risk of contact; it can be widely used in equipment such as refrigerators, air conditioners, water heaters, rice cookers, washing machines, televisions, etc.
