Product description

Votronic charging converter VC 1212-45 IUoU-Li – Efficient battery charging even for short distances

The Votronic VC 1212-45 IUoU-Li charging converter guarantees optimal and rapid charging of your supply battery directly from the alternator while driving. Unlike conventional isolating relays, this charging booster increases the charging voltage to the ideal level for your battery type, enabling a full charge in the shortest possible time. Even with long charging leads or voltage fluctuations, the device ensures a stable voltage and protects both the battery and connected loads from dynamically regulated alternators.

Excellent charging performance and protection features

The charging converter offers high charging power even on short journeys, significantly improving the energy balance of your supply circuit. Thanks to the IU1oU2oU3 charging technology, a full charge is achieved on longer journeys without the risk of overcharging. The integrated automatic power control ensures that the starter battery is charged first when the vehicle electrical system is under high load, ensuring your vehicle's starting capability at all times.

Adaptable charging characteristics for different battery types

The VC 1212-45 IUoU-Li is adaptable to various battery types, including four different LiFePO4 types, thanks to a battery selector switch. Furthermore, temperature compensation ensures automatic adjustment of the charging voltage to the battery temperature, enabling charging even in extreme temperatures.

Easy installation and comprehensive compatibility

Installation of the charging converter is straightforward and requires no intervention in the vehicle's starter circuit. The integrated on-board power filter enables trouble-free parallel operation with solar panels, mains chargers, and other charging sources. Galvanic isolation between the input and output ensures safe and trouble-free charging, even in large vehicles or with long supply lines.

Security and protection functions

The charging converter features comprehensive safety features such as reverse polarity protection, short-circuit protection, and reverse discharge protection. It also offers remote control connections and battery status indicators to facilitate operation and monitoring.
