Mastervolt Mac Plus 12/12-50 + CZone

The Mac Plus 12/12-50 + CZone is an advanced DC-DC charger designed specifically for marine and boating applications. It ensures your service battery receives a reliable, fast, and safe charge, even in demanding conditions, making it an essential component for maintaining optimal power management on your vessel.

Enhance Your Service Battery Performance

Service batteries are crucial for powering your boat's essential systems, but they often suffer from inadequate charging, especially with smart alternators and start/stop systems that provide slow and insufficient charges. The Mac Plus DC-DC charger addresses this issue by delivering a quick, safe, and consistent charge to your service battery. It intelligently detects when the engine is running, ensuring the starter battery remains protected and preventing any potential drainage.

Mastervolt Quality You Can Trust

With the Mac Plus 12/12-50 + CZone, you benefit from Mastervolt's renowned 3-step+ charge algorithm, which ensures a fast and efficient charge even for completely flat batteries. Its robust design is built to withstand harsh marine environments, featuring temperature-optimized charging and a durable aluminum housing that offers superior protection against dust and water ingress. Additionally, its power-efficient, fanless design ensures silent operation, enhancing your boating experience without unnecessary noise.

Unmatched Power Flexibility

The Mac Plus offers exceptional power flexibility with its wide DC input range, allowing it to work with all DC sources. It can charge two batteries from a single alternator or charger and supports a full range of battery chemistries, including lithium. Compatibility with modern alternators like Euro 5 and 6 ensures constant power delivery, even when the alternator is inactive.

For larger power needs, parallel configurations of up to ten units can provide over 100 amperes. Advanced high-frequency technology and modern microprocessors minimize power loss when switching between 12V and 24V systems. Additionally, the Mac Plus features analog voltage sense ports to compensate for voltage drops, ensuring consistent and proper charging.

Advanced Monitoring and Control

Integrate the Mac Plus seamlessly into your marine power system with its compatibility with CZone®, NMEA 2000®, and MasterBus®. This ensures superior monitoring and control, allowing you to optimize performance through various controllers and high-quality MOSFETs. Configuration is effortless with MasterAdjust, the CZone configuration tool, or the on-board DIP switches, providing flexibility to suit your specific needs.
