When Does The Battery Isolator Kit Disengage? This voltage sensitive relay ( VSR ) is an automatic charging relay for dual. The battery isolator kit will disengage when the battery is no longer able to hold a charge.The Solid State Isolator contains two isolation circuits. Prevents loads on auxiliary battery from draining the starting battery, a Smart Isolator is more flexible than traditional Battery Isolators: It works with all types of alternator. 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.Ĭartek produces two types of Battery Isolator GT and XR.īoth systems isolate the battery from all electrical circuits, in accordance with FIA requirements, by disconnecting the negative terminal of the battery from chassis/earth. Smaller and lighter than traditional isolators. There are no efficiency losses due to diodes. It allows bi-directional charging from the alternator or from shore power. However, the main difference between these two units is the method used to stop the engine.
The GT unit has a 40A 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. 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. However, our system also allows multiple kill switches to be installed and the fitment of two external ‘kill’ buttons, one on each side of a race car, has become popular safety feature.Īll switches/push- buttons are connected to the Isolator via light weight, low current wiring and configured such that the Battery Isolator will automatically turn off should any of the wire connections become broken in a catastrophic accident.
SKU: SBI12 Categories: REDARC, Isolators. How much cranking current will it handle?īoth units are capable of handling 500- 600 amps of cranking current depending on the duration.
Smart Start SBI 12V 100A Redarc Battery Isolator. The REDARC Smart Start® SBI2 is a microprocessor-controlled battery isolator used in dual battery systems as a solenoid priority system.
