Detailed description

The Mastervolt Mac Plus 12/12-50 + CZone is a sophisticated DC-DC charger-converter and stabilized power supply device designed to optimize the performance of service batteries in marine and mobile applications. Built to overcome the limitations of modern alternators, including Euro 5/6 and start/stop systems, it ensures fast, safe, and consistent charging, avoiding the slow and insufficient charging often observed with these configurations.

Advanced charging performance and versatility

The Mac Plus 12/12-50 + CZone integrates Mastervolt’s 3-step+ charging algorithm, ensuring rapid and efficient recharging even for deeply discharged batteries. It is compatible with a wide range of battery technologies, including flooded, gel, AGM, spiral, and Lithium-Ion batteries (including LiFePO4). Its wide DC input range (10–16 V) allows it to accept various power sources and charge two batteries simultaneously from a single alternator or charger. Intelligent engine-running detection ensures the starter battery is never discharged. With a nominal input and output voltage of 12 V and a maximum output current of 50 A, it delivers a nominal output power of 675 W.

Robustness and system integration

Designed for the most demanding environments, the Mac Plus 12/12-50 + CZone features a high-quality aluminum housing, providing superior protection against dust and water ingress (IP23). Its fanless, naturally cooled operation and temperature compensation optimize battery lifespan. This model is natively compatible with MasterBus, CZone, and NMEA 2000 networks, offering advanced monitoring and control capabilities. This integration simplifies automation and intelligent management of the entire onboard electrical system, positioning it as a more complete solution than standalone DC-DC converters or non-communicating chargers from brands like Victron Energy or Sterling Power, which require additional interfaces for such advanced integration.

Enhanced capabilities and certifications

With a maximum output power of 725 W, the Mac Plus 12/12-50 + CZone provides stable power and protects sensitive equipment thanks to its 2% output voltage stabilization at extreme temperatures. It supports parallel operation of up to ten units, enabling charging capacities well above 100 amps. Analog voltage sensing ports compensate for voltage drops for consistent charging. Certified to CE, E-Mark, SAE J1171, and ISO 8846 Ignition Protected, it ensures optimal safety and reliability for mobile and marine applications. Configuration is simplified via integrated DIP switches, MasterAdjust, or the CZone configuration tool. Its efficiency exceeds 95% at nominal input voltage and full load.
