Cartek Solid State Battery Isolator XR
The CK-BR-08-B XR Battery Isolator unit does not have a power input or power output. Instead it sends a signal which is wired up to either a Power Distribution Module or Motorsport ECU that has an ignition switch signal input. The ECU or Power Distribution Module will then shut down when it see’s this signal – which then kills the engine.
The new XR battery isolator (CK-BR-08-B) is 30% smaller size and 40% lighter weight than the previous ‘standard’ and GT isolators. The XR version offers even more benefits and performance when compared with traditional mechanical master-switches and electro/mechanical safety cut-outs.
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.
GT or XR?
Cartek produces two types of Battery Isolator GT and XR.
Both systems isolate the battery from all electrical circuits, in accordance with FIA requirements, by disconnecting the negative terminal of the battery from chassis/earth. However, the main difference between these two units is the method used to stop the engine. The GT unit has a 30A switched power output which can be used as the main power feed for most ECUs and/or ignition systems while the XR unit outputs a low current, ‘Ignition Off’, signal which is compatible with most motorsport ECUs and PDMs. This latter method of engine kill means that the XR is smaller and lighter than the GT and incorporates a sealed, circular connector.
How Is It Operated?
The Isolator can be controlled by any number of switches although the usual configuration is one internal on-
How much cranking current will it handle?
Both units are capable of handling 500-
The new Battery Isolator XR also features a 0.5 sec time delay between transmitting the engine kill signal and disconnecting the battery allowing ECUs time to perform a shutdown sequence before electrical power is lost.
We recommend and stock kits with blue kill buttons. Typically the blue button is associated with electrical cutoff, whereas the red is associated with fire systems. However you can order a red button kit, message us to request these.
