Alfatronix Low Voltage Disconnect

The device works to ensure that there is always sufficient voltage remaining in the battery to start a vehicle engine or ensure power is available for other critical applications.

In addition the PT-T versions offer a timed facility. This will disconnect the output after a set time after the ignition has been turned off.
