GT Solid State Battery Isolator

Designed to be chassis mounted close to the vehicle’s battery allows the heavy current power cables to be kept as short as possible. Typical installation requires one external kill button and just one internal on-off switch which are all interconnected using low voltage wiring. However, the flexibility of this system also allows additional kill button/devices to be incorporated as well as full operation using just a single on/off switch if necessary. Microprocessor controlled incorporating false trigger detection, internal temperature monitoring and short-circuit protection offer unprecidented safety. At just 150g this Isolator is also incredibly light.

For Use With High Compression and V8 Engines

Is the Isolator FIA approved?
Unlike race seats, harnesses and fire extinguishers the FIA does not have an approval procedure for Master Switches. However, most FIA race and rally championships require cars to be fitted with a spark-proof master switch to isolate the battery from all electrical systems and stop the engine. The Cartek Battery Isolator meets these requirements.

FIA ARTICLE 13 : GENERAL CIRCUIT BREAKER
The general circuit breaker must cut all electrical circuits, battery, alternator or dynamo, lights, hooters, ignition, electrical controls, etc.) and must also stop the engine.

MSA External Circuit Breaker
8.1. The circuit breaker, when operated, must isolate all electrical circuits with the exception of those that operate fire extinguishers.

How Does It work?
The Solid State Isolator contains two isolation circuits. The first breaks the connection between the negative side of the vehicle’s battery from chassis/earth, thereby isolating the battery power from all electrical circuits, while the second cuts power to the engine electrics and thereby stops the engine from running.

Standard or GT ?
Cartek produces two types of Battery Isolator 'Standard' and GT.
We recommend the Standard Battery Isolator for normally asperated engines upto 3000cc and the GT for engines over 3000cc. We also recommend the GT version for all highly tuned race engines with high compression, turbo engines and diesel engines.
The new PDM specific Battery Isolator, CK-BSF-01, has the same power as the GT.

Why Solid State ?
Solid State means no moving parts, all power switching is fully electronic. Early types of electrical isolation were by large mechanical master-switches while more modern systems have utilised electro-mechanical solenoids. Both of these types of systems contain mechanical electrical contacts which, due to the combination of high electrical current and the shocks and vibration of the race car environment, sparking between the contacts occurs which results in contact erosion and eventual unreliability. This Solid State Isolator is also filled with a hard setting resin which prevents any ingress of dust, dirt or water therefore further increasing its stength and reliability.

How Is It Controlled?

The two electronic isolation circuits are controlled by microprocessors and incorporate various safety systems including over-temperature and over-current monitoring. These microprocessors also monitor the kill switches/buttons for instant activation without false triggering. The unit will instantly trigger into isolation mode when any of the kill buttons are struck or on detection of any fault or break in switch wiring circuits.

How Is It Operated?
The Isolator can be controlled by any number of switches although the usual configuration is one internal on-off switch and one external kill button. All switches/push-buttons are connected to the Isolator via light weight, low current wiring.
If required, multiple kill switches/devices can be incorporated, alternatively the system can be configured to be operated by a single on-off switch/pushbutton. The Isolator will also automatically trip into isolation mode if any wire connection becomes broken due to fatigue or accident.
