Büttner Elektronik MT 1240 Duo automatic charger 12 V 40 A

These MT chargers have been developed for high charging powers of 40 to 60 amps. These units also have all the features and advantages of the MT chargers already described.

In addition to the existing charging outputs for the starter and on-board battery, this series is also equipped with a second main charging output. This makes sense especially in the marine sector, when other independent batteries (bow thruster) are to be charged in addition to the starter and on-board battery

In addition, all devices have a power limit switch. In the event of a weakly fused mains supply, this can be used to reduce the input power in three stages.

Of course, the battery temperature sensor is also included in this series of devices, so that it is guaranteed that the on-board battery/ batteries are always and everywhere optimally charged.

General information MT Chargers Duo-Automatic
Our MT chargers Duo-Automatic are the classics in our program. over the years, we have always further developed these devices and thus set standards in charging technology. Thanks to a sophisticated component cooling system, these chargers can be found in many expedition vehicles that travel to the hottest regions of the world. But it is not only their robust appearance that makes this series probably the most innovative chargers in the world. We have done everything possible to make the devices as user-friendly as possible

To give an example: the removable remote control can be used to read the current operating status in the interior and activate silent night charging. If it is forgotten to deactivate it the next morning, the charger automatically terminates the night mode. Due to their cooling system - which can be an advantage in some motorhomes because of the lack of ventilation - these units are slightly heavier and also turn out larger than the PL series.
