Alfatronix Low Voltage Disconnect

The PowerTector Battery Guard is a solid state battery device that will monitor the source voltage and disconnect the equipment from the battery if the voltage falls below a pre-determined level.

Reference: Low Voltage Disconnect
Card 1 Card 2

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.
