This DC 12–36V low voltage cutoff module is designed to protect batteries from over-discharge by automatically disconnecting the load when the battery voltage reaches the preset value. It is suitable for 12V, 24V and 36V lead-acid batteries, lithium-ion batteries and solar battery systems. The module features a 3-digit LED display and onboard buttons for easy parameter adjustment. Users can set the low voltage disconnect value, reconnect difference value and delay turn-on time according to their system needs. Settings are saved automatically after power off. Please note that this product is a voltage controller and relay switch module. It only turns the output on or off and does not increase, decrease or stabilize voltage. For long-term stable use, the working current should be kept under 8A. The maximum current is 10A when voltage is below 12V and less than 8A when voltage exceeds 12V.
