Boost Your Service Battery
Too often, service batteries don’t get the charge they need.
This is a problem made worse by
smart alternators and start/stop systems,
which result in slow and insufficient charges.

The Mac Plus DC-DC charger solves this problem,
providing a quick, safe, and consistent charge
to your service battery.
And, by knowing when the engine is running
and providing charge,
you can be sure that the Mac Plus
will never drain your starter battery.

Fast and safe charging, even during short trips
Fanless design for silent operation
Suitable for flooded, Gel, AGM and Li-Ion batteries (incl. LiFePO4)
Even charges fully depleted batteries
Engine run detection protects starter battery
Adjustable current limits to meet Euro 5/6 requirements
Voltage stabilization protects sensitive equipment, lights and loads
Parallel operation to obtain charging capacities well over 100 Amps
MasterBus, CZone and NMEA 2000 compatible, for intelligent system monitoring and automation
Temperature compensation and voltage sense for an optimal charging result
E-Mark/R10 certification for mobile applications
Power supply mode offers stable power for sensitive loads
Heavy duty connections for easy installation and quick set up via DIP switches
