12V power outage protection module, battery charger/discharger controller with automatic shut-off

Features: 12V Battery Undervoltage Controller: This controller protects 12V batteries against undervoltage. It allows you to set an undervoltage value and a starting value. When the battery voltage is below the undervoltage value, the module automatically disconnects the load; when it is above the starting value, it reconnects it. It has a settings memory function and a real-time digital voltage display. Its undervoltage and starting adjustment buttons make it easy to use. A time-delay function prevents unwanted disconnections: the load is disconnected 6 seconds after the voltage remains below the undervoltage value.
