Mastervolt Mac Plus 24/12-50A

The Mastervolt Mac Plus DC-DC charger optimizes battery charging for vehicles and watercraft with intelligent alternator systems. Available in 12V/12V-50A and 12V/24V-30A versions, this robust charger addresses voltage drop issues over long cable runs and compensates for the variable output of modern Euro 5/6 compliant intelligent alternators. It employs a proven three-stage charging method to ensure a full battery charge even on short trips, significantly extending battery life. The fanless design ensures silent operation while maintaining a high efficiency of over 95 percent. Compatible with flooded, gel, AGM, and lithium-ion batteries including LiFePO4 chemistry, the Mac Plus features automatic engine run detection to protect starter batteries. Voltage stabilization protects sensitive devices from voltage spikes, and parallel operation allows charging currents over 100A. With dimensions of 255 x 165 x 66 mm and a weight of 2 kg, the device includes MasterBus connectivity for system monitoring, temperature and voltage compensation, adjustable current limiting for Euro 5/6 compliance, and DIP switches for easy configuration. E-marked for mobile applications, it provides reliable charging for service vehicles, recreational vehicles, trucks, and boats, where auxiliary batteries are positioned far from charging sources or in systems with regenerative braking. The transparent housing allows for visual inspection, while the rugged connections simplify installation in demanding environments.
