Mac Plus 24/24-30 + CZone

Boost the Service Battery

Too often, service batteries don’t get the charge they need. This is a problem made worse by smart alternators and start/stop systems, which result in slow and insufficient charges. The Mac Plus DC-DC charger solves this problem, providing a quick, safe, and consistent charge to the service battery. And, by knowing when the engine is running and providing charge, users can be sure that the Mac Plus will never drain a starter battery.

Proven Mastervolt Quality

Users get peace of mind knowing that they have the best on board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even for completely flat batteries.

A robust design holds up in even the harshest conditions, with battery temperature-optimized charging and a high-quality aluminum housing to ensure superior protection against dust and water ingress. The power-efficient design also allows the Mac Plus to operate silently and without a fan.

Total Power Flexibility

With a wide DC input range, the Mac Plus allows for all DC sources and can charge two batteries from a single alternator or charger. It supports a full range of chemistries and battery types, including lithium. It also functions seamlessly with modern alternators such as Euro 5 and 6, ensuring proper charging by providing constant power, even when the alternator is inactive.

Parallel configuration of up to ten units will provide over 100 amperes. Advanced high-frequency technology with modern microprocessors ensures minimal power loss when switching from 12V to 24V and vice versa.

Analog voltage sense ports are also available to compensate for voltage drops and maintain proper charging.

Superior Monitoring & Control

Compatibility with CZone®, NMEA 2000®, and MasterBus delivers truly superior monitoring and control and ensures Mac Plus integrates easily into complete systems. Achieve the best performance possible via various controllers and high-quality MOSFETs. And configure the Mac Plus with ease via MasterAdjust, the CZone configuration tool, or even via the on-board DIP switches.
