PRODUCT DESCRIPTION
Mastervolt ChargeMaster Plus 12/100-3 CZone/MBus Battery Charger – 12V, 3 Outputs
The Mastervolt ChargeMaster Plus 12/100-3 CZone/MBus is an all-in-one battery charger for fast, safe charging of up to three batteries. It integrates a multicharger with two outputs, one in/output, a DC-DC converter, a current limiter and a VSR in a single device, replacing auxiliary chargers, battery isolators and VSRs to reduce system complexity and cost. It works anywhere in the world and charges multiple batteries while you are underway.
Charges Every Battery Type
Charge Lithium-Ion, Gel and AGM batteries, in large or small banks, on a single charger. Every battery is charged with the fast and safe 3-Step+ method.
- Revival mode: automatically revives even fully depleted batteries
- Priority Charge: redirects available power to the lowest battery for faster charging
- Smart Input: charges all three batteries from a single alternator for continuous charging on the go
- Safe Charge: quickly recognizes the State of Charge for extended battery life
Global Charging for Marine and Mobile Use
The charger handles worldwide AC voltages and frequencies, with a very wide operating range of 80-275 V AC, 35-70 Hz. It resists large voltage fluctuations and high temperatures, so it keeps working in harsh environments. Extended specifications offer 20% more output at 14.4 V and 80% charging power at 60 °C.
Compliant with CE, ABYC, UL, SAE, CEC and RCM/C-Tick standards.
Simple to Install and Easy to Read
The charger shows the charge phase of all three outputs in an easy-to-understand way. Robust, ergonomic connections save installation time, and the compact unit is easy to connect. An integrated VSR eliminates the need for additional components and channels alternator energy to the batteries.
MasterBus, CZone and NMEA Communication
The ChargeMaster Plus CZone/MBus supports MasterBus, CZone and NMEA communication, so it can talk to displays, shunts and power systems, including standards such as FireCan and CANopen. It can also act as a power supply for delicate communication equipment or during the construction phase of a boat.
