Avoid problems with your service battery!
The Mastervolt Mac Plus 24/24-30 + CZone is the perfect solution for the best on-board voltage. Modern vehicles with intelligent alternators and start-stop systems place high demands on the battery supply. The Mac Plus DC-DC charger ensures that your service battery is always sufficiently charged.
Traditionally, a service battery is linked to the starter battery by means of a charge relay. The starter battery is located close to the alternator and receives most of the charge current. However, the service battery is usually further away. Long cables cause voltage drops, leading to slow charging, resulting in failing appliances and premature failure of the battery.
Modern, fuel efficient engines are equipped with smart alternators, following regulations such as Euro 5 and Euro 6. Instead of a constant output, smart alternators provide a variable voltage; after a brief charging period, voltage is reduced and the charging stops. Furthermore, the energy produced by regenerative braking leads to voltage peaks. Service batteries coupled in the traditional way will receive hardly any charge and may be damaged by these peak voltages.
To solve these issues, Mastervolt introduces the Mac Plus DC-DC chargers, available in 12 V or 24 V. The Mac Plus monitors the service battery and compensates the voltage loss. The proven 3-step charge method ensures a quick and safe charge. Moreover, by stabilizing the charge voltage, Mac Plus protects your service battery and sensitive equipment.
The Mac Plus is your battery’s best friend. It monitors your service battery and makes sure it’s always fully charged, maximising the lifetime of your battery.
Connected and intelligent
The Mastervolt Mac Plus + CZone is more than just a battery-to-battery charger. Thanks to integration in CZone, NMEA 2000 and MasterBus, it becomes the central element of your on-board network. Monitor all important parameters, adjust charging profiles and automate processes - all conveniently from one central point. High-quality MOSFETs ensure precise control and maximum efficiency.
