Product Information

Electronically controlled relay for simultaneous charging of two batteries (for example, start and load battery in the off-roader) - the disconnecting relay is installed between the two batteries and remains open until the filling level of one of the two batteries has reached a predetermined voltage value. Now the relay will close and both batteries will be fully charged. This graduation ensures that the starter battery is fully charged even during frequent short-range operation.

If the motor is switched off and the alternator does not supply any current, the relay opens automatically and ensures electrical separation of the batteries. This ensures that there is enough current at the start of the vehicle.

The VSR Relay is a cost-effective and easy way to build a dual battery system that does not require any control, external displays, and the associated cabling and installation work. The relay is installed near the two batteries and does not need any user interaction. As soon as the voltage falls below the drop-out voltage, a 5-second switch-off delay occurs so that the battery is not overloaded. The scope of delivery includes fastening material and material for grounding.
