  • Switch-on: 13.7V +0.1 / 27.47V +0.1
  • Cut-off voltage:     12.8V +0.15 / 25.6V +0.15
  • no connection of alternator (D+) necessary
  • the electronic module automatically detects the startup of the charging alternator
  • Suitable for alternators and charging currents of up to 140A OperationThe charging current distributor allows charging of two batteries simultaneously. As soon as the engine starts and the starter battery reaches the switch-on voltage, the distributor is activated so that two separate batteries (starter and secondary battery) can be charged at the same time.
    If the voltage drops below the cut-off voltage (e.g. when the engine is turned off), the distributor is deactivated and the batteries are isolated from each other. This system ensures that the starter battery is not discharged. Additionally, it protects the sensitive electronics connected to the secondary battery form voltage spikes that can occur when the engine starts.

    Connection scheme

    Connection is very easy, the distributor has 3 outputs:
    • 1x plus (+) starter battery
    • 1x plus (+) secondary battery
    • 1x ground (-) (black cable)
