Mastervolt ChargeMaster Plus 12/50-3 Charger

Description

The Mastervolt ChargeMaster Plus 12/50-3 is a high-output three-bank charger designed for boats that need fast battery recovery, broad battery compatibility, and integration with a Mastervolt electrical system. Its 3-Step+ charging process manages the batteries through the appropriate charging stages automatically and is capable of charging depleted banks while helping maintain battery performance over time.

Auto-ranging input allows the charger to work across common international shore-power voltages and frequencies without manual switching. The front display shows charging current, voltage, charge phase, battery condition, and MasterBus status. A memory function helps prevent overcharging when the AC supply is unstable, and power-factor regulation helps make efficient use of limited generator capacity.

The three charging outputs allow multiple battery banks to be maintained from one unit, while DC power-supply mode can continue supplying onboard loads even if batteries are not connected. MasterBus compatibility supports central, local, or remote monitoring, configuration, and control with compatible equipment. Solid metal-to-metal electrical connections with strain relief are designed to reduce corrosion and overheating at the terminals. For larger 12V marine battery systems, the ChargeMaster Plus combines substantial charging capacity with network-ready control and global shore-power flexibility.
