5 x Alfatronix PowerTector Battery Guard 9Vdc-32Vdc (Automatic Referencing) 40A – PT40
The PowerTector Battery Guard is a solid state 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, so 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.
All units in the range are supplied pre-programmed for a variety of scenarios offering higher or lower disconnect voltages to and it is quick and simple to select the correct programme to suit your needs whether it is to avoid battery damage due or to protect key equipment. There are six units in the range from 10A to 200A. The 10A and 20A unit offer a simple inline system, usually wired to a specific piece of equipment. These units do not require chassis mounting and simply connect and tie wrap neatly within the wiring system.
In addition to the standard PowerTectors, the PT-T versions offer a timed facility. This will disconnect the output after a set time after the ignition has been turned off. If required, during this timed period, the voltage can still be monitored and disconnected if it falls below a set level to protect the battery power and system. The unit will re-activate when the ignition has been turned on again and the battery voltage has reached 8.5Vdc (12V systems), 17Vdc (24V systems).
