This voltage protector provides automatic protection for home appliances against under-voltage, over-voltage, power interruptions, surges, and overloads. It helps safeguard sensitive electronics and extends the lifespan of connected devices by preventing damage caused by unstable power supply. Low or high voltage levels can harm the normal operation of appliances, reduce service life, or even damage compressor motors in air conditioners, refrigerators, and freezers. Sudden power outages and re-energizing of the electrical network can create strong voltage spikes that are hazardous to compressors. This protector automatically disconnects the load during such events and provides a delayed restart (180 seconds) to ensure safe reconnection, offering reliable compressor protection. Applications: Plug the protector into a wall outlet and connect appliances such as air conditioners, refrigerators, freezers, TVs, LCD/Plasma displays, DVD players, home theater systems, computers, laptops, washing machines, dryers, ovens, dishwashers, and other household appliances (without compressors) into the output socket. Installation: The unit can be mounted on a wall using the built-in hanging hole on the back.
