The battery is the central element of the vehicle's electric system. High attention has to be paid to it concerning maintenance and care, and, above all: It has to be charged correctly. This is particularly true to vehicles with two battery circuits, such as special purpose vehicles, ambulance cars, campers or offroad vehicles, where a special auxiliary battery supplies the electric appliances, systems and equipment on board. The charging state of this supply battery decides which electric appliance can be switched-on and how long it can be switched-on. The lifetime of the battery is decisively influenced by the battery type, the charging and discharging processes, by eventual total discharge and also by the used charging technology. This concerns the range of campers and offroad-vehicles, as well as intervention vehicles, where the electric equipment is very often decisive for life and limb.
When charging a vehicle battery, it is important, that 100 % output is always available and that the charging current and the charging voltage are kept to the correct values during the complete charging cycle. In keeping with the times, this can only be achieved with units according to advanced switch mode technology (SMT), since -in contrast to former transformer-rectifier units- they distinguish by complete and precise adjustment of all instabilities (low voltage, deviating frequency and sine curve, power failure). Due to an exactly defined characteristic line of charging IU1oU2, the VOTRONIC automatic chargers in switch mode technology allow quick and effective charging of lead-acid, gel and AGM/fleece batteries, treating the battery careful at the same time. This reliable concept of charging technique, which has emerged from the close cooperation with leading battery and vehicle manufacturers, can be used for a wide range of applications on the one hand, and, on the other hand, it can despite be adapted to the requirements of the user. The units are designed for installation in campers, offroad-vehicles, ambulance cars and special purpose vehicles, and they are particularly suitable for stationary installation in the industrial range.
