Boost the charging voltage of your service battery!Charging the service batteries on board of a vehicle or vessel can be challenging. Recharging tends to take a long time and batteries may not receive a full charge. This is a common problem found in boats, service vans, campers and trucks. Smart alternators and start/stop systems make the problem even worse.Robust DC-DC charger guarantees optimal condition of your service batteryTraditionally, a service battery is linked to the starter battery by means of a charge relay. The starter battery is located close to the alternator and receives most of the charge current. However, the service battery is usually further away. Long cables cause voltage drop, leading to slow charging, resulting in failing appliances and premature failure of the battery.Modern, fuel efficient engines are equipped with smart alternators, following regulations such as Euro 5 and Euro 6. Instead of a constant output, smart alternators provide a variable voltage; after a brief charging period, voltage is reduced and the charging stops. Furthermore, the energy produced by regenerative braking leads to voltage peaks. Service batteries coupled in the traditional way will receive hardly any charge and may be damaged by these peak voltages.To solve these issues, Mastervolt introduces the Mac Plus DC-DC chargers, available in 12 V or 24 V. The Mac Plus monitors the service battery and compensates the voltage loss. The proven 3-step charge method ensures a quick and safe charge. Moreover, by stabilizing the charge voltage, Mac Plus protects your service battery and sensitive equipment.FeaturesFast and safe charging during short tripsFanless design for silent operationSuitable for flooded, Gel, AGM and Li-Ion batteries (incl. LiFePO4)Charges even fully depleted batteriesEngine run detection protects starter batteryAdjustable current limits to meet Euro 5/6 requirementsVoltage stabilisation protects sensitive equipment, lights and loadsParallel operation to obtain charging capacities well over 100 AmpsMasterBus for intelligent system monitoring and automationTemperature compensation and voltage sense for an optimal charging resultE-mark certification for mobile applicationsPower supply modeHeavy duty connections for easy installation and quick set up via DIP switches The non-isolated Mac Plus models have an electrical connection between the input and output.Features:Low costsEfficient: low heat generationCompactSuited to applications with negative earthingApplicationsBoost charge voltage when service battery is located further from charging source or in systems with a smart alternator. When a stable power supply or different system voltage is needed.Euro 5/6 solutionCharging service batteries in Euro 5/6 applications?The Mac Plus provides constant power to the service battery, even when the alternator is inactive.Parallel operationThe parallel configuration of several units will provide you over 100 amperes. Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12 V and vice versa.Solid ConnectionsGalvanized brass connection block with screw terminal or chrome-plated fast-on for DC in/out for the Mac/Magic models. The robust M8 connections of the Mac Plus prevent any loosening due to vibrations.In the BoxMac Plus Converter/Charger6m Temperature SensorUser ManualUser Manual & Installation instruction .input-wrapper a { text-decoration: none; / Removes underline / background-color: transparent; / Ensures no background color / } .input-wrapper a:hover { text-decoration: underline; / Adds underline on hover / background-color: transparent !important; / Removes grey highlight / }
