Features

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.

RobuA robust DC-DC charger guarantees the mal condition of your service battery.

Traditionally, a service battery is linked to the starter battery using a charge relay. The starter battery is 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 battery failure.

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, the voltage is reduced, and the charging stops. Furthermore, the energy produced by regenerative braking leads to voltage peaks. Service batteries coupled traditionally will receive hardly any charge and may be damaged by these peak voltages.

Mastervolt introduced the Mac Plus DC-DC chargers to solve these issues, and they are 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 stabilising the charge voltage, Mac Plus protects your service battery and sensitive equipment.

Features

• Fast and safe charging during short trips.
• Fanless design for silent operation.
• Suitable for flooded, Gel, AGM and Li-Ion batteries (incl. LiFePO4).
• Charges even fully depleted batteries.
• Engine run detection protects the starter battery.
• Adjustable current limits to meet Euro 5/6 requirements.
• Voltage stabilisation protects sensitive equipment, lights and loads.
• Parallel operation to obtain charging capacities well over 100 Amps.
• MasterBus for intelligent system monitoring and automation.
• Temperature compensation and voltage sense for an optimal charging result.
• E-mark certification for mobile applications.
• Power supply mode.
• Heavy duty connections for easy installation and quick set up via DIP switches.

Applications

Boost 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 solution

Charging service batteries in Euro 5/6 applications?

The Mac Plus provides constant power to the service battery, even when the alternator is inactive.

Parallel operation

The 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 Connections

Galvanised 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.
