The Mac Plus CZone voltage converter from Mastervolt is a DC-DC converter with a charging function that generates a stable 12V output voltage of up to 50 A / 750 W from a 12V, 24V or 48V on-board power system and is specially designed for modern Euro 5/6 alternators. Thanks to galvanic isolation between input and output, connected loads and communication devices remain stably supplied even with fluctuating battery voltage. The Mac Plus CZone can be integrated into a philippi P-Bus system via the CMB interface. Philippi supplies the Mastervolt Mac Plus CZone as a Mastervolt system partner, including system consultation.
Advantages at a glance
- Stable 12V supply regardless of on-board voltage and cable length – protects sensitive electronics, lighting, and communication devices from voltage drops.
- E-Mark certified and designed for operation with modern Euro 5/6 alternators – suitable for retrofitting in vehicles with smart alternator control.
- Parallel connection of several devices for power supplies over 100 A – scalable for larger loads.
- Automatic on/off function prevents deep discharge of the starter battery.
- Compact, silent housing with robust M8 connectors for vibration-proof installation.
The Mac Plus CZone regulates the voltage both up and down, compensating for voltage drops over long cable runs and load fluctuations. An integrated temperature compensation extends the service life of the connected battery. This makes the Mac Plus CZone voltage converter suitable for refit projects on yachts with separate on-board voltages as well as for motorhomes and off-road vehicles where 12V consumers need to be reliably supplied from a 24V or 48V system.
As a Mastervolt system partner, Philippi integrates the Mac Plus CZone via the CMB interface (order no. 0 7100 0030) into existing Philippi on-board power systems, so that the operating status and parameters of the Mac Plus CZone are visible on the Philippi system monitors PSL and PSM 3. Philippi advises on the selection of the appropriate input voltage variant and on commissioning.
