Batteries always in perfect condition with innovative Teleco Group TBC3i PRO charger

Keeping on-board camper batteries charged and maintained is essential to ensure they provide long-lasting performance. To obtain the best possible results, the Teleco Group has developed the innovative TBC3i PRO charger, characterised by outstanding build quality and light, compact design. This last aspect is an important one as it provides precious additional space inside the camper.

TBC3i PRO charger design combines several latest-generation modules, such as a mains battery charger capable of handling rated voltages of 110 or 230V, a charge converter for the vehicle alternator and a charge regulator with MPPT technology for the solar panels. This means the camper batteries will, whatever the energy source, be automatically charged at all times, whether the vehicle is parked or on the move. The integrated charge converter always ensures a good recharge during trips both short and long.

All models are equipped with a system that keeps the batteries charged even during long storage periods. They also have 8 different charging curves for different battery types: lead-acid, AGM, GEL and LiFePO4 batteries. Wiring and connections have been minimised, making installation fast and simple.

TBC3i PRO battery chargers also feature the (optional) TCP3i PRO control panel with an LCD display indicating the status of each power source, starter battery voltage, service battery voltage and instantaneous charge current. When the solar module is working, the display shows instantaneous solar power (W) and energy values (Wh and Ah). Charging form the AC mains can be activated or deactivated manually. Moreover, in countries where the mains protection current is particularly low, capacity can be reduced (AC Power Limit). A special protection function ensures AC mains charging is reactivated if the service battery is at risk of running completely flat.

The display is backlit to ensure excellent legibility under all circumstances while consuming very little power. Assembly, which can also be done after installation of the battery charger, is made easier by the plug-and-play connection (via the supplied 5-metre cable).

TBC3i PRO battery chargers and TCP3i PRO control panels are already available through the Teleco Group sales network.
