1800J
Surge Protection: With a surge absorption capacity of 1800 Joules, it shields your refrigerator, freezer, and gaming computer from damage caused by lightning strikes and power surges. Rated at 15 amps/1800 watts, it readily drives high-power appliances without tripping or overheating.
Automatic Voltage Control: Power is immediately cut off when the voltage exceeds 130 volts or falls below 100 volts. This shields your appliances from voltage drops and spikes that most surge protectors cannot detect.
Smart Indicator Light: Green indicates normal operation. Red indicates overvoltage/undervoltage power is off. Blue indicates delayed restart the device will wait 30 seconds for the voltage to stabilize before reconnecting. This prevents frequent starts/stops, a leading cause of compressor failure. Most surge protectors lack this feature, but this product does.
Built-in Alarm: An alarm sounds immediately when overvoltage/undervoltage is detected. Combined with the red LED indicator, problems are detected immediately.
Safety features: Equipped with overload, overcurrent, surge, and overvoltage protection; the casing is made of flame-retardant UL94 V-0 grade material. The compact wall-mount design (2*2* 4.5 in) allows for installation behind a refrigerator, under a table, or in any confined space
