Product details

Complete solution for fast and safe charging
ChargeMaster PLUS is the next generation of battery chargers that integrates multiple functions into one single device.
Replacing auxiliary chargers, battery isolators and VSR, ChargeMaster Plus reduces system complexity and cost. Designed for versatility, it charges virtually any combination of three batteries in a fast and safe way and works anywhere in the world.

With the new Battery’s Best Friend architecture, ChargeMaster Plus is capable of charging a multitude of battery chemistries, sizes and voltages. All batteries are charged with the fast and safe 3-step+ charge method. Other unique features are:
  • Revival mode: automatically revives even fully depleted batteries
  • Priority Charge: redirect available power to the lowest battery, for faster charging
  • Smart Input: charge all three batteries from one single alternator for continuous charging on the go
Global charging
The ChargeMaster Plus handles worldwide AC voltages and frequencies. Resisting large voltage fluctuations and high temperatures, it keeps working in harsh environments. For marine and mobile markets, ChargeMaster Plus is CE, E-mark, ABYC, UL, SAE, CEC and RCM/C-Tick compliant.

System simplicity
The 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. An integrated VSR eliminates the need for additional components and also ensures that the alternator's energy is transmitted to the batteries.

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.

Further features
  • MasterBus, CZone and NMEA 2000 communication interface
  • Universal charger with two outputs, one input and output, DC-DC converter, current limiter and VSR
  • Combines lithium-ion, gel, or AGM batteries as well as large or small 12/24 V battery banks on a single battery charger
  • Charges multiple batteries at a time, even while you're on the move
  • Safe charging: quickly detects charging status, ensuring a longer battery life
  • Very wide operating range of 80-275 V AC, 35-70 Hz
  • Compact, easy to install and connect
The ChargeMaster PLUS simplifies charging systems. It's a complete solution that ensures faster and safer charging!
