The 12/25-3 is fitted with a temperature controlled fan and is able to charge three batteries simultaneously with a total maximum charge rate of 25 amps to two batteries. A third 3A output can be connected to the starter battery. All types of batteries can be charged: gel cells, AGM or wet batteries. Another important feature is the automatic compensation for low incoming shore power. Even at 180V AC, the charge current will be at maximum. A slight reduction will follow after connection to a 117V shore power connection. All models are equipped with a LED status indicator displaying the stage of the charge cycle: bulk-absorptionfloat (battery fully charged). Automatic voltage compensation and temperature compensation are standard features. An extended remote panel is optional.
