Product details

The complete solution for fast and safe charging
ChargeMaster PLUS is the next generation of battery chargers that integrates multiple functions into one single device.
ChargeMaster Plus features the new "Battery's Best Friend" architecture, which allows it to charge a multitude of battery chemistries, sizes and voltages with the safe and fast 3-step+ charging method. For faster charging, Priority Charge redirects power to the weakest battery, Revival mode automatically brings even fully depleted batteries back to life, and the Pre-Float function (charge retention) eliminates the risk of overcharging smaller batteries.
The charging profile for MASTERVOLT MLI lithium-ion batteries is also included, and it is possible to create a customised, user-defined profile for lithium batteries from other manufacturers, for example, via an optional USB interface and the MasterAdjust software*.

Global charging
ChargeMaster Plus can handle all possible mains voltages and frequencies worldwide. The battery chargers can resist large voltage fluctuations and high temperatures, making them suitable for the harshest environments - perfect for use on boats and in cars. ChargeMaster PLUS units comply with CE, E-mark, ABYC, UL, SAE, CEC and RCM/C-Tick standards.

System simplicity
ChargeMaster PLUS chargers are self-explanatory! They display the charging phase of all three outputs in an easy to understand way. Robust and ergonomic connections save installation time.

Powerful connections
In modern applications, all components work hand in hand. The CAN-based MasterBus allows the charger to communicate with displays, shunts and power systems, including communication standards such as CZone, NMEA and CANopen. The ChargeMaster PLUS can operate as a power supply for sensitive communication equipment or during the construction phase of a boat.

Additional features
  • MasterBus, CZone and NMEA 2000 communication interfaces
  • Universal charger with three outputs
  • Any type of lead-acid battery, including gel or AGM batteries, as well as large or small battery banks, can be gently charged on a single battery charger.
  • Also suitable for charging MASTERVOLT MLI lithium-ion batteries
  • Adjustable to the parameters for lithium batteries of other manufacturers via MasterBus USB interface (optional) and free Masteradjust software
  • Charges multiple batteries simultaneously
  • Safe charging: quickly detects charging status, ensuring a longer battery life
  • Very wide operating range of 80-275 V AC, 35-70 Hz for worldwide use
  • Compact, easy to install and connect
ChargeMaster PLUS ensures faster and safer charging!
