Mastervolt ChargeMaster charger
The ChargeMaster guarantees fast and complete battery charging. Thanks to the innovative 3-stage charging process, the batteries have higher performance and a longer lifespan. The devices can be integrated into the MasterBus network (except for ChargeMaster 12/10 and 12/15-2) and can therefore be monitored, configured, and controlled centrally, locally, or remotely.
The illuminated display of the ChargeMaster (exception: ChargeMaster 12/10 and 12/15-2) shows all important information: charging current, charging voltage, charging phase and measurement of the battery content and/or measurement of the battery status as a percentage of the available ampere-hour capacity.
The auto-ranging (automatic range setting) ensures perfect, fully automatic charging, regardless of the available mains voltage (90-265V AC, 50 or 60Hz).
Three equivalent charging outputs. The outputs of the smaller Charge-Master models are equipped with a 2-meter cable for plug-and-play installation, while the larger models have one output for, for example, a service battery, as well as two 10A outputs that are ideal for starter batteries.
Mastervolt ChargeMaster battery chargers provide a constant DC output in addition to the charging function, so that, for example, lights can be switched on and the refrigerator continues to run (power supply function).
Features:
- For recreational and semi-professional use.
- Suitable for all battery types, including lithium-ion batteries.
- 3-stage plus charging technology for fast and complete charging, also charges empty batteries.
- Safe and complete charging process thanks to standard safety features.
- Easy connection and quick installation.
- Can charge multiple battery banks simultaneously.
- Integrated system functionality (MasterBus) in combination with other Mastervolt products (except 12/10 and 12/15-2).
- Clear control panel.
