1. Connecting the power supply, the yellow indicator light is on when the voltage is 175 Vac ~ 260 Vac. After a delay of about 5 minutes, or you can press the ON & OFF button directly, the green light is always on and the power supply begins to output voltage;2. After the power supply is connected, when the voltage is lower than 175 Vac or higher than 260 Vac, it will directly enter voltage protection mode. At this point, the red light is still on and power is not output;3. When the product is in protection mode (the red light is on), if the voltage is higher than 190V or the high voltage is higher than 240VAC, the yellow light is on and changes to normal working state after a delay approximately 5 minutes;4. The ON & OFF button only works when the voltage is within the normal operating range; If you are in voltage protection mode, the ON & OFF button will not action;5. When the product enters the normal state, if the voltage is unstable and it is out of the normal voltage range, the product directly enters the voltage protection mode and the device is not powered by the device.
