Features 1、KNOB ADJUSTMENT: The voltage undervoltage protection module can be connected with an external knob to adjust the voltage, and the operation is simple. 2、MAIN PURPOSE: Battery undervoltage switch module, used to turn off the power supply of a resistive load when the voltage falls below a certain value. 3、SAFE OPERATION: When the voltage rises, the module will automatically turn on the load again to prevent the battery from being overloaded, burned or damaged. 4、LOAD ON AND OFF: When the undervoltage can be set between 10V‑11V, the load will be disconnected, and between 11V‑14.2V, the load will be started. 5、GOOD PERFORMANCE: Including 2pcs undervoltage protection module, for 12V battery, with small voltage error, less interference, used for electrical equipment.
