A digital low voltage protector is a device designed to protect electrical equipment or appliances from damage caused by low voltage conditions. Users can easily set the parameter to disconnect the battery automatically when it reaches a preset voltage, thus preventing over-discharging, preventing potential harm to the connected devices. These protectors are particularly useful in regions where voltage fluctuations are common, ensuring the safe operation of sensitive electronics. | HIGH-ACCURACY: 3-digit LED screen display. It can easily read output voltage and setting parameters. Display Accuracy: 0.1V, Control Accuracy: 0.1V. | Reset: When the power is off, press and hold the two buttons at the same time, and then power on. At this time, the screen displays "888", indicating that the factory settings are restored. The factory-set protection value: 12V, difference value: 2V.Difference Value" is the value between the battery voltage to disconnect and the battery voltage to reconnect. | Board Size: 57 X 42 X 19mm/2.24 X 1.65 X 0.75inch(L*W*H), Input Voltage Range: DC12-36V, Control Accuracy: 0.1V, Power Consumption: <1.5W, Instantaneous maximum current before circuit breaker trip: 20A. | With power-off protection, it will save your settings in the event of an unexpected loss of power. This feature is crucial for electronic devices that require specific configurations, as it prevents the loss of critical data and allows you to resume work where you left off.
