Unstable Voltage Protection Switcher Refrigerator LED TV PC Protector Delayed Power-on Voltage Protection Power Socket Muhafiz Switch
- 1.Voltage protection indicator
- Switch on the power, when the voltage is lower than 175V or higher than 260V, the red light is on, and the electrical jade protection state is entered. The socket has no electrical output.
- 2.Delayed power-on indicator light:
- When the power is switched on, only when the voltage is at 175v-260 v, the red light goes out and the yellow light comes on, and start the time-delay power on (the button can be cancelled), and the yellow light will turn off after 4-5 minutes.
- 3.Voltage output indicator lamp:
- When the delayed power-on indicator is off, the green light is on, the relay is closed, and the outlet starts to have a power output.
- 4.Start button:
- Turn on the power on function, press the key to cancel the power on delay and quickly enter the work.
