Mastervolt ChargeMaster 12/25-3

ChargeMaster 25/12-3

Get the most out of your batteries with the ChargeMaster series, plug in and charge anywhere in the world. Mastervolt's ChargeMaster guarantees fast and complete charging of your batteries wherever you are. Thanks to Mastervolt's innovative 3-step+ charging process, batteries also perform better and last longer.

All ChargeMasters can be easily connected to a MasterBus network with just one cable and one connector (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2 and ChargeMaster 24/6). In addition, you have the option of central, local or remote monitoring, configuration and control of your system.

Clear display

A clearly illuminated display on the ChargeMaster provides all important information: charging current, charging voltage, charging phase and battery content measurement and/or battery condition measurement as a percentage of available Ah capacity. The display also gives an indication of MasterBus communication. Three buttons next to the readout panel make it easy to operate the entire system.

ChargeMaster is available in different models to guarantee you the perfect battery charger for every situation and need.

Charge your batteries with every voltage

Mastervolt ChargeMaster provides maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). 3-stage+ charging technology ensures fast and complete charging, while cos phi 1 regulation makes the most of limited generator capacity.

Robust connections

Solid metal-to-metal connectors equipped with strain relief prevent corrosion and overheating.

Charges multiple battery banks

The ChargeMaster series has three equal charging outputs. Those of the smaller ChargeMaster models are pre-installed with two meters of cable for a plug & play solution, while the heavier models have one full output (for example for your service battery) and two 10 A outputs, perfect for your starter batteries.

DC power supply

Even if the batteries are not connected, Mastervolt ChargeMaster battery chargers can provide a constant DC output so you can turn on lights or keep the fridge cold.
