Mac Plus 24/24-30 Converter
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
battery
Traditionally, 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.
The Mac Plus is your battery’s best friend. It monitors your service battery
and makes sure it’s always fully charged, maximising the lifetime of your
battery.
Features:

- Suitable for flooded, Gel, AGM and Li-Ion batteries (incl. LiFePO4).
- Charges even fully depleted batteries.
- Engine run detection protects 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
