Undervoltage protection of car battery STU 34611

Product detailed description

The safety module protects your car battery from excessive discharge. It disconnects power to the device connected to the module if the battery voltage level is too low. As soon as the battery charge level returns to normal (e.g. after starting the vehicle), it restores power to the connected additional appliances.

It can be used to control the switching on of an electrical device when the vehicle is started or switched off when the vehicle is stopped.

The detection voltage value can be set using the built-in LED display.

Suitable for use e.g. to control car DVR camera, car radio, refrigerator and other vehicle electronic devices.
