Ensure the safety and longevity of your electrical appliances with our automatic surge protection device. Features: IP20 protection class: Dust-proof and resistant to brief water exposure, suitable for use in damp environments. Voltage Indicator Lights: Yellow Light: Activates when voltage reaches 175-260VAC. Green Light: Illuminates after a 5-minute delay or with a direct press of the ON & OFF button, signaling power output commencement. Red Light: Indicates voltage protection mode has been activated due to lower than 175VAC or higher than 260VAC voltage levels, cutting off power output. Protection Mode: Automatically activates if voltage falls outside the normal operating range. The voltage normalizes within 190-240VAC after approximately 5 minutes, and the device resumes normal function. ON & OFF Button: Operable only when voltage is within the safe range. Disabled during voltage protection mode. Automatic Protection: Instantly engages when voltage stability is compromised, ensuring no power is delivered to connected devices when outside of normal range.
