Voltage Protection Switch High & Low Voltage Guard Digital Display

Specifications Current: 16A Voltage: 230V50Hz Delay Time: 10 seconds Power: 3680 watts Low Voltage Protection Range: 150–210V High Voltage Protection Range: 230–280V Operating Temperature Range: -10°C to +50°C Description 1. Connect the power supply. The default settings are 270V for high-voltage protection, 170V for low-voltage protection, and a 10-second delay. 2. Press the SET button to enter the high-voltage settings page. The digits will flash; press the + or - button to adjust the high-voltage protection range. Press the SET button again to proceed to the low-voltage settings. The digits will flash again; press the + or - button to adjust the low-voltage protection range. Press the SET button once more to enter the delay time settings. After power is restored, press the + or - button to adjust the delay time. Press the SET key again to confirm that all data is correct. 3. When the applied voltage is within the normal operating range, the blue light will illuminate; When the product is in overvoltage or undervoltage protection mode, the red light will illuminate and power will be automatically cut off; When the product is powered down due to a transient overvoltage or undervoltage, the delay protection will automatically activate, and there will be no power output. 4. Once the delay countdown ends, the product resumes operation. Note: The reset voltage is automatically detected and may be lower or higher than 10V. · High-voltage protection: Resumes when the voltage is 10V lower than the original setting; · Low-voltage protection: Resumes when the voltage is 10V higher than the original setting.
