Mastervolt is proud to introduce a brand-new generation of reliable boat battery chargers, featuring the ChargeMaster. It is ideal for systems on board small to medium-sized boat yachts, as well as mobile applications, such as mobile homes and road-side installations. Here’s a summary of the good news.

Ready to charge three battery sets at once :
- 3 DC outlets to simultaneously charge three battery sets to the max
- One heavier outlet (40 up to 100A)
- Two lighter outlets of 10A
- Suitable for all battery types (GEL, AGM and lead)

HF technology for extreme charge efficiency :
- High Frequency technology offers more than 90% charge efficiency
- 3-Stage Plus charging process provides complete charge per cycle
- An end to the annoying hum found with heavier transformers
- Charging process lengthens battery life span
- Efficiency ensures minimal environmental pollution

Autoranging: Plug in and charge from 90V up to 265V :
- Autoranging guarantees batteries can be charged anywhere and at any -time as long as voltage is available
- Input suitable for voltage from 90 up to 265V and frequencies of 50 and 60Hz
- Also functions in extreme temperatures (-25°C up to +60 °C)

Charging with almost all boat generators :
- The ChargeMaster functions in combination with almost all AC generators
- Latest technologies and Cos Phi 1 regulation ensure ultra-high efficiency
- Intelligent electronic controls make generator overload impossible

Secure charging process :
- Charging occurs safely and gradually via Mastervolt 3-Stage Plus charging method
- Complete charge in all circumstances with the right power for the connected batteries
- Optimally secured against overload by, among other things, a standard supplied temperature sensor

Easy monitoring and controls :
- Brightly lit and easily readable LCD display
- 3-button controls: The selection buttons can be used to see the charge current, charge voltage and charge phase of all three battery sets and allow data history analysis
- MasterBus function offers extensive options for marine remote control and monitoring

Smart and safe connections :
- Robust connections, well-protected from boat electronics
- No need to connect boat cables to the PCB itself
- Direct metal-to-metal contacts improve charging progress and prevent corrosion and overheating

Easy installation due to compact design :
- Lightweight and easily manageable
- Smallest volume on the market in relation to power (5.2 litre/kW)

Connection box for all cables :
- Underneath the ChargeMaster is a separate connection box within which all connections are integrated
- Connection box easily accessible through sailboat cover boat plate with four ‘unloseable’ screws
- Cables easily concealed and can – if required – exit the battery charger for boats on three sides

Installed at will :
- Installable anywhere: on a flat surface, below deck or vertically on the wall with a standard supplied mounting bracket
- Mounting, installation and maintenance in only a few steps
- Clear documentation
