Battery charger TBC3i PRO 30/20/250
Innovative TBC3i battery chargers offer outstanding construction quality and have a particularly light, compact design that helps save valuable space inside the camper.
Wiring and connections have been minimised to make installation fast and simple.
TBC3i battery chargers consist of a combination of latest-generation units; these include a mains battery charger, a charge converter from the alternator and a charge regulator with MPPT technology for solar panels, ensuring there is always an energy source in the camper.
Batteries are always charged automatically, both during the standby or when driving.
Depending on the model, the integrated charge converter always ensures a complete recharge during both short and, of course, long trips.
All of them have an integrated system to maintain battery charge even during long periods of storage and have eight different charge curves for lead-acid, AGM, GEL and LiFePO4 batteries.
Their LCD displays have been specially developed for these units and show all the key information.
These battery chargers are compatible with all car park charging units

LCD control panel for TBC3i PRO 30/20/250 battery charger
TCP3i PRO is a control panel that displays the status of the individual power sources, 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 from the AC mains can be activated or deactivated manually or AC Power Limit can be reduced (e.g. in countries where the mains dove protection current is particularly low. A special protection function ensures AC mains charging is reactivated if the service battery is at risk of running completely flat.
The display is illuminated and ensures excellent legibility while consuming very little power.
Assembly is made easy by plug-and-play connection and can be also be completed after installation of the battery charger
The compact design makes it ideal for installation in any part of the vehicle.
