Detailed description

The Mastervolt Mac Plus 24/12-50 + CZone is an advanced DC-DC charger converter designed for efficient energy management on board vehicles and vessels equipped with 24V systems requiring stable 12V power. This specific model from the Mac Plus range converts a nominal input voltage of 24V (range 19–30V DC) into a stabilized 12V output (range 10–15V) with a maximum current of 50A and a nominal output power of 710W (750W max).

Technical Performance and Efficiency

The Mac Plus 24/12-50 integrates a proven 3-stage+ charging algorithm, ensuring fast and safe charging of service batteries, even during short trips. It is compatible with a wide range of battery technologies, including lead-acid (flooded, gel, AGM, spiral), lithium-ion (LiFePO4), and traction batteries, with user-configurable parameters. Its efficiency exceeds 95% at full load and nominal input voltage, peaking at 97%, minimizing energy losses. Unlike basic DC-DC converters, the Mac Plus features engine-running detection to protect the starter battery and provides stable power even when the alternator is inactive, compliant with Euro 5/6 alternator requirements.

System Integration and Advanced Features

This converter stands out for its native compatibility with MasterBus, CZone, and NMEA 2000 protocols, offering superior system integration for monitoring and automation. It can be configured via MasterAdjust, the CZone configuration tool, or directly using its integrated DIP switches. The Mac Plus 24/12-50 can also operate in stabilized power supply mode for sensitive loads, ensuring constant output voltage and protecting electronic equipment. For installations requiring higher charging capacity, up to ten units can be configured in parallel, allowing output currents well above 100A. Although it lacks galvanic isolation, it compensates for voltage drops via its voltage sensing ports and optimizes charging with its included battery temperature sensor.

Robust Design and Installation

Housed in a high-quality aluminum enclosure (255 x 165 x 66 mm, weighing 2 kg), the Mac Plus 24/12-50 offers IP23 protection against solid objects larger than 12.5 mm and water splashes, ensuring durability in marine and mobile environments. Its fanless design ensures silent operation. It features three M8 terminals for power cables (10–50 mm²) and an 8-pole screw terminal for control signals (0.75–1.5 mm²). The product complies with CE, E-Mark/R10, SAE J1171, and ISO 8846 Ignition Protected standards. Installation requires a minimum clearance of 10 cm on each side for optimal airflow and must be performed using appropriately sized cables, e.g., 10 mm² [AWG 8] for input and 16 mm² [AWG 6] for output in this 24/12-50 model. It must not be mounted directly above batteries to avoid exposure to corrosive sulfur emissions.
