All-in-one solution for faster and safer charging
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 at high speed 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.
ChargeMaster Plus Series Features
- MasterBus, CZone and NMEA communication.
- Multicharger with two outputs, one in/output, DC-DC converter, current limiter and VSR
- Combine Lithium Ion, Gel or AGM, and large or small 12/24V battery banks on a single charger (24V models only)
- Charges multiple batteries while being underway
- Extended specificitions: offers 20% more output at 14.4V and 80% charging power at 140°F (60°C)
- Safe Charge: quickly recognize the State of Charge for extended battery life
- Very wide operating range of 80-275V AC, 35-70 Hz
- Compact, easy to connect and quick to install
Other unique features are:
- Revival mode:
automatically revives even fully depleted batteries - Multi voltage:
charge 12V starter battery in a 24V system, without additional components (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, ChargeMaster Plus is CE, ABYC, UL, SAE, CEC and RCM/C-Tick compliant.
System simplicity
Nowadays, equipment must be self-explaining. The ChargeMaster Plus displays the charge phase of all three outputs in an understandable way. Robust and ergonomic connections save installation time. An integrated VSR eliminates the nod for additional components and ensures that the alternators energy is funnelled through to the batteries.
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. Models with the addition “CZone integrated” do not only support MasterBus, but also support CZone and NMEA communication, without the need of additional interfaces. The 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. All models of the ChargeMaster Plus series can operate as a power supply for delicate communication equipment, or during the construction phase of a boat.
