Kemo M102A Secondary Battery Charger 6 - 24 V/DC

The Kemo M102A secondary battery charger is suitable for lead-acid batteries from 6-24 V/DC. With this battery switch, two batteries can be charged separately from each other using a single charging source (car alternator, solar panels, wind turbines, chargers, etc.). For charging currents up to max. 10A (with cooling 20A). The charging current is distributed so that an empty battery is charged more strongly than an almost full battery, ideal for motor caravans when a battery is used to operate a TV, radio, etc. And the second battery must remain full to start the engine. Or for weekend homes, when a battery for the alarm system must not be drained. A balancing current of approx. 0.005A can flow between the two batteries (in normal operation at 12V). This serves to enable any upstream solar controller to perform any necessary voltage control of the batteries.

Technical data

• Connectable batteries: 2 batteries with the same voltage 6-24 V/DC
• Max. charging current: 10A, with cooling max. 20A (total current)
• Dimensions: approx. 87 x 60 x 33 mm (without mounting brackets)

Installation instructions:

Depending on the load, the module may heat up to a greater or lesser extent. The heat is generated at the aluminum plate at the bottom of the module and, under certain circumstances, must be cooled by mounting it on a cooling surface in accordance with the installation instructions. It is important that the module is mounted flat on a cooling, flat cooling plate using 4 M3 screws or 2.9 mm sheet metal screws. This can also be the rear wall of a metal housing. It is important that the aluminum underside of the module does not warp in the process! The screw heads must rest on the metal sheet of the module and not on the plastic edge of the module! The module must also not warp during installation (if the surface is not flat). The reason: The electronic SMD components are soldered directly onto the inside of the aluminum base of the module over a thin insulating layer, and if the aluminum base of the module warps, the solder joints will come loose and the module will be defective.
