LOW VOLTAGE DISCONNECT

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.

• Using the simple programming

terminal, select the pre-set

disconnect voltage according

to your requirements.

• LED indicates operational status.

• Audible alarm and/or visual

indicator can be installed in the

dashboard or cockpit to alert

operator of a potential problem.

• Switch terminal allows the unit to

be operated via the ignition or a

manual switch.

• The PowerTector battery guards

offer excellent protection for

communication and other mission

critical applications

feaTureS

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.

The 40A and 60A units are connected

by M6 brass bolts, the 100A and 200A

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 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

fittted. This allows the units to be

reactivated for four minutes to allow

emergency actions to be performed.

• All PowerTectors from 40A

upwards are mounted in a rugged

die cast aluminium casing with

glass filled polycarbonate cover

providing terminal protection and

insulation.

• Smaller units; 10A and 20A,

are available in a lightweight,

polycarbonate casing that can be

simply fitted in the wiring, like an

inline fuse without the need to

drill the vehicle chassis.

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

action 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 8.5Vdc (12V systems),

17Vdc (24V 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 programme

to suit your needs.
