Description
The Mac Plus 24/24-50 + CZone is the highest-power model in the range, a non-isolated DC-DC charger that maintains a 24 V service battery from a 24 V source at up to 50 A (1425 W). Using the proven Mastervolt 3-step+ charge algorithm it delivers a quick, safe and consistent charge even to completely flat batteries, while engine-run detection ensures the starter battery is never drained. It also works seamlessly with Euro 5/6 smart alternators, supplying constant power even when the alternator is inactive.
A power-efficient, fanless aluminium housing keeps the unit silent and well protected against dust and water. It supports Gel, AGM and Lithium Ion (incl. LiFePO4) batteries, and up to four units can be paralleled for charging capacities well over 100 A. Analog voltage sense ports compensate for voltage drop, and a power supply mode provides stable output for sensitive loads.
Compatibility with CZone, NMEA 2000 and MasterBus gives superior monitoring and control, with configuration via MasterAdjust, the CZone tool or the on-board DIP switches.
