Provides automatic surge protections to your electrical appliances, ensuring their safety and longevity. Features: With an IP20 protections class, this electrical socket is dust-proof and can withstand BriefExposure to water, making it suitable for use in damp environments. Connecting the power, the yellow light is turn ON when the voltage is at 175-260VAC. After delay around 5 minutes, or you can press the ON & OFF button directly, the green light is AlwaysON, and the power starts to output voltage. After the power is connected, when the voltage is lower than 175VAC or higher than 260VAC, it enters the voltage protections mode directly. At this time, the red light is AlwaysON, and the power is not output. When the product is in the protections mode (the red light is ON), if the voltage higher than 190VAC or the high voltage drops BelowThan 240VAC, the yellow light will be ON, and it will enters the normal working status after a delay of about 5 minutes. The ON & OFF button works only when the voltage is in the normal working range. If in the voltage protections mode, the ON & OFF button can't be use. When the product enters the normal status, if the voltage unstable, and it's out of the normal voltage range, the product will enters the voltage protections mode directly and device is no power output.
