Mastervolt Mac Plus 24/24-30 + CZone

The Mac Plus 24/24-30 + CZone is the ultimate DC-DC charger designed specifically for marine and boating applications. It ensures your service battery receives a quick, safe, and consistent charge, even in the most demanding conditions. With advanced features and seamless integration capabilities, the Mac Plus keeps your boat’s electrical systems running smoothly.

Boost Your Service Battery

Service batteries on boats often suffer from inadequate charging, especially with the advent of smart alternators and start/stop systems that deliver slow and insufficient charges. The Mac Plus DC-DC charger effectively addresses this issue by providing a rapid and reliable charge to your service battery. It intelligently detects when the engine is running to supply power, ensuring your starter battery remains unaffected and never drained.

Unmatched Mastervolt Quality

Trust in the renowned Mastervolt quality with the Mac Plus charger. Utilizing the Mastervolt 3-step+ charge algorithm, the Mac Plus delivers efficient and straightforward charging, even reviving completely flat batteries. Its robust design withstands harsh marine environments, featuring temperature-optimized charging and a durable aluminum housing that offers superior protection against dust and water ingress. Additionally, the power-efficient, fanless design ensures silent operation, perfect for maintaining a peaceful onboard atmosphere.

Total Power Flexibility for Marine Applications

Designed with versatility in mind, the Mac Plus features a wide DC input range compatible with all DC sources, allowing you to charge two batteries from a single alternator or charger. It supports a comprehensive range of battery chemistries, including lithium, and works seamlessly with modern alternators such as Euro 5 and 6. This ensures consistent power supply and proper charging, even when the alternator is inactive.

For increased power needs, you can configure up to ten units in parallel to achieve charging capacities exceeding 100 amperes. Advanced high-frequency technology and modern microprocessors minimize power loss during voltage switching, while analog voltage sense ports maintain proper charging by compensating for voltage drops.

Superior Monitoring & Control for Seamless Integration

Enhance your boat’s electrical system with the Mac Plus’s compatibility with CZone®, NMEA 2000®, and MasterBus®. This ensures superior monitoring and control, allowing the Mac Plus to integrate effortlessly into your existing systems. Optimize performance through various controllers and high-quality MOSFETs, and easily configure the charger using MasterAdjust, the CZone configuration tool, or the on-board DIP switches.
