About this item Applicable Devices: The voltage surge protector outlet is suitable for a wide range of home appliances and electronic equipment, including air conditioners, refrigerators, freezers, ice makers, washing machines, microwave ovens, dishwashers, coffee makers, bread machines, water heaters, electric fans, and more. LED Status Indicators: Built-in LED indicators clearly display power status, including Normal Output, High Voltage (Over 140VAC), Low Voltage (Below 90VAC), and Delay Mode, allowing you to easily monitor voltage conditions in real time. Delay Protection Function: Features a 30-second delay function that activates when voltage fluctuations occur. Power output resumes only after the voltage stabilizes, helping prevent repeated start-stop cycles and reducing potential damage to connected appliances. Automatic Voltage & Surge Protection: Automatically disconnects power when abnormal voltage is detected, protecting equipment from over-voltage, under-voltage, voltage f
