The Solid State Battery Isolators from CARTEK are very small and highly reliable alternatives to the traditional mechanical master-switch and have been designed to overcome all of the problems and restrictions associated with mechanical and electro/mechanical safety cut-outs.
When fitted to a race car our Solid State Battery Isolator simultaneously isolates the battery and kills the engine immediately when triggered in accordance with FiA safety regulations. Isolators can be supplied stand alone for connection to customers own switches/buttons or as full kits with high quality, fully waterproof, internal and external buttons and safety stickers.
The XR Battery Isolator is the latest generation of motorsport master-switch devices from CARTEK.
At 30% smaller size and 40% lighter weight than the previous ‘standard’ and GT isolators, this XR version offers even more benefits and performance when compared with traditional mechanical master-switches and electro/mechanical safety cut-outs.
All CARTEK Battery Isolators are designed to be chassis mounted close to the battery which 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 thin, lightweight wiring. However, the flexibility of this system also allows additional kill button/devices to be incorporated for increased safety. Microprocessor controlled incorporating false trigger detection, internal temperature monitoring and short-circuit protection offer unprecedented reliability and safety.
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.
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 XR Battery Isolator has the same power as the GT.[top] Why Solid State?
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.[top]
