Real-Time Voltage Monitoring: The prominent digital LED screen displays the current incoming grid voltage in real-time, which reads 228 Volts in the image.Automated Disconnection: It actively shields equipment by cutting off power whenever the main line encounters high voltage spikes, brownouts (low voltage), or intense electrical surges.Built-in Smart Delay Timer: Once power fluctuations stabilize back to a safe range, the device holds off on reconnecting power for a designated delay cycle (often 10 seconds or up to 3 minutes). This delay protects refrigeration and air conditioning compressors from being severely damaged by rapid, consecutive power cycling.Universal Interface: It incorporates a standard 13A multi-plug socket layout, allowing it to easily accommodate diverse plug formats without needing an extra adapter.
