All ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2 and ChargeMaster 24/6). This offers the option for central, local, or remote monitoring, configuration, and control of your system.
Clear Display
A clearly lit display on the ChargeMaster provides all essential information: charge current, charge voltage, charge phase, and battery content measurement or battery condition measurement as a percentage of available Ah capacity. The display also indicates MasterBus communication. Three buttons adjacent to the read-out panel allow for easy operation of the entire system. The ChargeMaster is available in various models to suit different needs.

Charging Capabilities
The Mastervolt ChargeMaster supplies maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect, fully automatic operation worldwide, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging technology guarantees fast and complete charging, while the cos phi 1-regulation optimizes the use of limited generator capacity.
Even if batteries are not connected, Mastervolt ChargeMaster battery chargers can provide a constant DC output, allowing you to turn on lights or keep the fridge cold.
Connections and Design
Robust Connections: Solid metal-to-metal connectors equipped with strain relief prevent corrosion and overheating.
Charging Multiple Battery Banks: The ChargeMaster series features three equal charge outputs. Smaller models are pre-installed with two meters of cable for a plug & play solution, while heavier models have one full output (e.g., for a service battery) and two outputs of 10 A, ideal for starter batteries.
