Duo Automatic Charger MT 1215

As with all products of BΓΌttner Electronics, the chargers are also Made in Germany and manufactured precisely according to their field of application.
Ideal charging is ensured by the latest IUoU charging characteristic curves combined with long-term activation and AGM/gel/LiFeP04 acid battery switching device. Additionally, this ensures unsupervised charging with automatic battery regeneration during longer periods of not using the caravan or in the winter. All devices can be connected in parallel to already existing chargers to increase the charging capactiy, and are secured against: short circuit, overload, polarity reversal, etc. A voltage regulation is integrated and ensures sufficient charging capacity even on weak or unstable mains. The control panel with display options and night-mode switch can be dismounted and mounted inside the vehicle as a remote (additional cable extension available).

From series MT-1240 on and up, the chargers have a second main charging output integrated. This makes charging of independently operating battery banks possible. These units also come with a 3-step switch reducing the power supply on camping sites with low fuse protection. All MT Chargers come with a temperature sensor for the caravan's battery to optimise their charging capacity.
