Description
The undervoltage protection module is used to automatically disconnect the load when the battery voltage drops below a set value. It protects 12V batteries from deep discharge and thus significantly extends their service life. After the voltage is restored, the load is automatically reconnected. Ideal for power systems, solar installations, automotive projects or DIY applications.
