Fully automatic dual isolation relay
+ 2 eyelets 25mm² M6
12 volts / 140 amps continuous load
Purpose:
If a second or (secondary) additional battery is to be installed in a vehicle, the installation of an isolation relay is highly recommended.
The purpose of installing this relay is to ensure that the connection between the two batteries is separated when the engine is switched off and the voltage falls below 12.8V. This ensures that the starter battery is not discharged if further energy is drawn from the additional battery.
When the engine is switched on, the charging voltage increases to over 13.3V (alternator control voltage ≥ 13.4), as a result of which the isolating relay closes the circuit and the starter and auxiliary batteries are charged simultaneously. The same applies if the charging voltage of the auxiliary battery increases to over 13.3V due to a connected charger or an installed solar system. This BSR isolating relay therefore works bidirectionally in both directions.
This relay is suitable for CAN bus vehicles. No alternator control voltage d+ or ignition plus is required.
Application areas:
- car
- buses
