Undervoltage Switch 12V Battery Low Voltage Cut off Automatic On Protection Controller

【PURPOSE】This is an undervoltage switch controller used to turn off the load power supply when the voltage drops below the set value. When the battery voltage increases to the set value, the module will automatically turn on the load again. 【EASY TO OPERATE】The battery under voltage controller is designed with an LED indicator light that can display whether the battery is under voltage. You only need to press the button to adjust the off and on voltage values. 【PROTECTIVE BATTERY】With this undervoltage controller module, it can prevent accidental operation to lower the voltage when starting a high current load, and help you protect the battery from excessive discharge,effectively extending the battery lIfe. 【FUNCTION】When our set voltage is 10.5V during voltage shutdown, and when the voltage is below 10.5V, if the voltage returns to above 10.5V within 5 seconds, the load will not be turned off. If it still falls below 10.5V within 5 seconds, turn off the load. 【RESTORE FACTORY SETTINGS】In normal state, press and hold the S1 and S2 buttons simultaneously until the display screen displays 888 to restore to the factory settings. This undervoltage controller is specifically designed for 12V batteries, please do not use other batteries.
