The ChargeMaster Plus by Mastervolt is the next generation of battery chargers that integrate multiple functions into a single device. Replacing auxiliary chargers, battery isolators, and VSR, The ChargeMaster Plus reduces system complexity and cost. Designed for versatility, it charges virtually any combination of two or three batteries in a fast and safe way and works anywhere in the world.

The ChargeMaster introduces the new Battery’s Best Friend architecture, capable of charging a multitude of battery chemistries, sizes, and voltages. All batteries are charged with the fast and safe 3-step+ charge method.

Offering other unique features such as:

• Revival mode: automatically revives even fully depleted batteries.
• Multi-voltage: charge a 12V starter battery in a 24 V system, without additional components (for 24 V models only).
• 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, the ChargeMaster Plus is CE, ABYC, UL, SAE, CEC/DOE, and RCM/C-Tick compliant.

System Simplicity

The ChargeMaster Plus displays the charge phase of all outputs. Robust and ergonomic connections save installation time. An integrated VSR eliminates the need for additional components and ensures that the alternators energy is funneled through to the batteries.

Powerful Communications via CZone Integration

In modern applications, all electrical components work together. The CAN-based MasterBus enables the ChargeMaster Plus to communicate with displays, shunts, and power systems including communication standards like CZone®, NMEA 2000, and CANopen (through additional interfaces).

Models with the addition of CZone do not only support MasterBus but also support CZone and NMEA 2000 communication, without the need for additional interfaces. This ChargeMasters Plus series can be configured via MasterBus or will accept a CZone configuration file just like any other CZone device. Other communication standards like ModBus, CANopen, LinBus, etc. are supported via additional interfaces.

This wide range of communication interfaces makes the ChargeMaster Plus ideally suited for system integration. In addition, the ChargeMaster Plus can operate as a power supply for delicate communication equipment, or during the construction phase of a boat.
