Solid-State Battery Guards

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. 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.

A Wide Range of Features

There are six units in the range from 20 A to 200 A. The 20 A unit offers 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. The 40 A and 60 A units are connected by M6 brass bolts, the 100 A and 200 by M10 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.

Manual Shutdown Facility

From 40 A upwards, the units have the facility to be manually shut down either through the ignition or a dedicated switch. In addition, from 100 A upwards the units can have an override switch fitted. This allows the units to be reactivated for four minutes to allow emergency actions to be performed.

Alarm & Disconnect Delay Feature

An alarm output is supplied which, once the 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 restart the engine or take other actions to maintain continuous power.

Timed Versions

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 time 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 reactivate when the ignition has been turned on again and the battery voltage has reached 8.5 Vdc (12 V systems), 17 Vdc (24 V systems).

Fully Programmable

All units in the range are supplied pre-programmed for a variety of scenarios offering higher or lower disconnect voltages and it is quick and simple to select the correct program to suit your needs.
