Does your service battery struggle with sufficient charge, especially in combination with modern 'smart' alternators (Euro 5/6) or long cable runs? The Mastervolt Mac Plus 24V to 12V DC/DC Converter Charger (50 Amperes) is the perfect solution. This powerful and smart device with article number 81205205 ensures a fast, safe, and consistent charging process for your 12V service battery from a 24V system on board your ship, camper, truck, or service vehicle.
The Mac Plus is more than just a DC/DC converter; it is a full-fledged 3-stage battery charger that compensates for voltage loss and stabilizes the output voltage. This not only protects your batteries but also all your sensitive 12V equipment and lighting.
Thanks to the fanless design, the Mac Plus is silent and the robust housing provides optimal protection. For extra capacity, you can easily connect multiple Mac Plus units in parallel for a charging current of over 100 Amperes. Choose Mastervolt quality and ensure optimal condition and lifespan of your service battery.
Features:
- Fast and Safe Charging: Uses the proven Mastervolt 3-stage charging algorithm for fast and safe charging, even during short trips. Also charges completely discharged batteries.
- Voltage Stabilizer: Protects sensitive 12V equipment, lighting, and other loads from fluctuations.
- Silent Operation: Fanless design (natural cooling) for silent performance.
- Euro 5/6 Compatible: Adjustable current limiting for optimal operation with modern alternators.
- Battery Type Flexibility: Suitable for wet, Gel, AGM, and Lithium Ion batteries (including LiFePO4).
- Parallel Connectable: Easily connect multiple units in parallel for charging capacities above 100 Amperes.
- Smart Communication: Compatible with MasterBus, CZone, and NMEA 2000 for advanced monitoring and automation.
