Mastervolt ChargeMaster Plus 12/75-3 battery charger.

ChargeMaster Plus 12/75-3

The ChargeMaster Plus is the next generation of battery chargers that integrates multiple functions into a single device. By replacing auxiliary chargers, battery isolators, and VSR, the ChargeMaster Plus reduces the complexity and cost of the system. Designed for flexibility, it safely and quickly charges almost any combination of two or three batteries.

• Revival mode: automatically revives even fully drained batteries.
• Multi voltage: charges 12 V starter batteries in a 24 V system without additional components (only for 24 V models).
• Priority Charge: redirects the available energy to the battery with the lowest level for faster charging.
• Smart Input: charges all three batteries from a single alternator for continuous charging while underway.

Global charging: The ChargeMaster Plus supports global AC voltages and frequencies. It withstands large voltage fluctuations and high temperatures, maintaining operation in harsh conditions. For marine and mobile markets, the ChargeMaster Plus complies with CE, ABYC, UL, SAE, CEC/DOE, and RCM/C-Tick standards.

System simplicity: The ChargeMaster Plus displays the charging phase of all outputs in an understandable way. Durable and ergonomic connections save installation time. A built-in VSR eliminates the need for additional components and ensures that the alternator's power is directed to the batteries.

Communication capabilities: The CAN-based MasterBus allows the ChargeMaster Plus to communicate with displays, shunts, and power systems. Models with the addition of CZone support CZone and NMEA 2000 communications without additional interfaces.

• Multiple charger with two outputs, one input/output, DC-DC converter, current limiter, and VSR.
• Charges Lithium Ion, Gel, and AGM batteries, with 24 V models able to charge large or small batteries in a single charger.
• Charges multiple batteries during transit.
• Extended specifications: offers 20% more power at 14.4 V and 80% charging power at 60 °C.
• Safe Charge: quickly identifies the charging status for longer battery life.
• Very distinct operating range of 80-275 V AC, 35-70 Hz.
• Compact, easy to connect, and quick to install.
