Battery charger Mastervolt ChargeMaster 24V 12A

ChargeMaster battery chargers

You get the most out of your batteries with the ChargeMaster series. After all, you can plug in and charge anywhere in the world. You are assured that your batteries are always charged quickly and completely. The ChargeMaster can charge multiple battery banks simultaneously, the convenience of combined functionality. All ChargeMasters can also be connected to a MasterBus network with one cable, one connection and one action. In addition to being super easy to install, you can also monitor, configure and operate your system centrally, locally or remotely. The ChargeMaster is available in various versions. This way you will always find the battery charger that best suits your situation and needs. This series of fully automatic battery chargers provide a pure DC voltage. The ChargeMaster can therefore also serve as a power source without connected batteries. The ChargeMaster also accepts an input voltage between 95 and 265V of 50Hz – 60Hz. Due to the sophisticated cooling with controlled fan and the design that allows the connection cables to be inserted sideways or backwards, this battery charger can also be used upright. Of course, the ChargeMaster is suitable for any battery type and works according to the 3-step charging process. This type of charger has three outputs as standard, two of which can supply max. 10 Amps for other battery sets. The ChargeMaster also has a unique memory function that prevents the charging cycle from starting all over again in the event of an interrupted charging process. By using a temperature sensor, the connected batteries are optimally charged. You can read the various charging phases of the connected battery sets via the display.

Battery charging at any voltage

The Mastervolt ChargeMaster delivers maximum output power thanks to auto-ranging. Auto-ranging guarantees perfect, fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging process also guarantees fast and complete charging. And thanks to the cos phi 1 regulation, you get the same charging current delivered with less generator power.

Robust connection points

Metal-to-metal connection points for solid connections to prevent corrosion and/or overheating of the connections.

Always on course with Mastervolt…

Mastervolt is happy to show you the way to an electrical system without weak links, for a reliable and silent power supply. Recreational or professional. With Mastervolt on board, you always choose power you can rely on.

Charge multiple battery banks simultaneously

The ChargeMaster series is equipped with 3 equal charging outputs. The input of the small ChargeMaster models is pre-assembled with two meters of cable, so truly plug & play! The heavy models are equipped with one full output (for your service battery, for example) and with two outputs of 10 A, ideal for starter batteries.
