The A-SAP SIC range of "Very Low Drop" automatic battery sensed isolators (charge sharers, split chargers) allow you to recharge two or more batteries simultaneously.
They automatically separate connected batteries to prevent discharge or "dumping" of the battery with higher remaining power into the one with the lower power. They will automatically charge the battery which has the lowest charge and then proceed to the other batteries.
The construction is heavy duty, with a rust proof, anodised aluminium case with wide cooling fins, to provide the maximum protection from overheating thus extending the isolator life.
The 'Very Low Drop" characteristic guarantees an extremely small loss of voltage at the exit. The isolator decrease to insignificant levels (less than 0.2V) the voltage drop on the way from the alternator to the battery. This is an innovative feature that differentiates our isolators from those of other manufacturers.
All isolators are to IP 685 protection standard.
You must use quality wiring of the correct size and specification to ensure that voltage drop is minimised.
