Product Overview

The PT20 is a PowerTector Battery Guard with Green LED for programming and output indication. It 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. This can work 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. The total discharge of a lead acid battery can also cause damage to the cells significantly shortening the life of the battery. The PowerTector unit can also be set to disconnect equipment at a lower voltage that will still protect the battery from total discharge, while allowing for maximum battery usage. A timed version is also available which will disconnect automatically a set period after the ignition has been switched off. The 20A unit offer a simple inline system, usually wired to a specific piece of equipment.
  • Alarm and disconnect delay feature
  • Insulated 6.3mm push-on flat blade connectors
