Pre-programmed Battery Guard 9-32 Vdc, 100 A, IP65 PT100

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. All PowerTectors from 40A upwards are mounted in a rugged die cast aluminium casing with glass filled polycarbonate cover providing terminal protection and insulation. The 40A and 60A units are connected by M6 brass bolts and use a three point mounting system to avoid rocking or stress to the electronics when mounted on uneven surfaces. Heat is dissipated into our custom manufactured die cast casing and all units will operate at full power without additional heatsink dissipation.

From 40A upwards, the units have the facility to be manually shutdown either through the ignition or a dedicated switch. In addition, from 100A upwards the units can have an override switch fitted. This allows the units to be re-activated for four minutes to allow emergency actions to be performed. An alarm output is supplied which, once the voltage threshold has been reached for 10 seconds, will activate, sounding an alarm or other indicating device for a further 50 seconds prior to disconnection. This allows the operator to re-start their engine or take other action to maintain continuous power.

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).

Units are equipped with insulated 6.3mm push-on flat blade connectors for earth, program, switch, override and alarm. Programming lead provided. They also have a green LED adjacent to programming terminal for programming and output indication. Units are over current protected (Limited by current sensing circuit), over heat protected (Limited by temperature sensing circuit) and protected against transients (Protected by filters and rugged component selection).

The PowerTector Battery Guards offer excellent protection for communication and other mission critical applications.
