mastervolt Mac Plus 12/24-30 + Czone DC to DC ConverterModel: 81205305 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 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.Get peace of mind, knowing that you’ve got the best on-board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even to completely flat batteries.A robust design holds up in even the harshest conditions, with battery temperature optimized charging and high-quality aluminium housing to ensure superior protection against dust and water ingress. The power efficient design also allows the Mac Plus to operate silently and without a fan.With a wide DC input range, the Mac Plus allows all DC sources and can charge two batteries from a single alternator or charger. It supports a full range of chemistries and battery types, including lithium. And it also functions seamlessly with modern alternators such as Euro 5 and 6, ensuring proper charging by providing constant power, even when the alternator is inactive.Parallel configuration of up to ten units will provide over 100 amperes. And advanced high-frequency technology with modern microprocessors ensures minimal power loss when switching from 12V to 24V and vice versa.Analog voltage sense ports are also available to compensate for voltage drop and maintain proper charging.Compatibility with CZone®, NMEA 2000® and MasterBus delivers truly superior monitoring and control, and ensures Mac Plus integrates easily into complete systems. Achieve the best performance possible via various controllers and high quality MOSFETs. And configure the Mac Plus with ease via MasterAdjust, the CZone configuration tool, or even via the on-board DIP switches.Specifications Specifications battery charger Battery temperature sensor yes, included Battery voltage sense Yes General specifications Status indicator yes, 3-color LED Communication protocol MasterBus, CZone & NMEA 2000 Output voltage 20-30 V Nominal output voltage 24 V Output voltage stabilisation 2 % at extremes of temperatures, load and input Output voltage ripple (peak peak) max. 1 % Max. output power 725 W Nominal output power 675 W Max. output current 30 A Output charge current (3-step mode) 30 A Nominal input voltage 12 V Input voltage range 10-16 V Max. input current 50 A Galvanic isolation no Voltage limited yes Efficiency > 95 % (at nom. input voltage, full load); peak 97 Parallel configuration yes Alarm contact yes, through MasterBus MasterBus powering no Engine run signal input yes (active high/active low) DIP switches yes, for basic setup Dimensions, hxwxd 10.0 x 6.5 x 2.6 inch Weight 4.4 lb Technical specifications No-load consumption < 2 mA Charge characteristic 3-traps+ Battery types flooded, Gel, AGM, spiral, Lithium Ion, traction, user defined 3-Step charge option yes (DIP switch settings) DC consumption < 5 mA Connections 3 x M8 terminal for cable diameters of 10-50 mm , (positive input, positive output, joint negative connection) 8-pole screw connection for cable diameters of 0.75-1.5 mm (remote on/off, temperature sensor, voltage measurement Temperature range (ambient temp.) -25 °C to 60 °C; derating > 40 Cooling natural cooling Protection degree IP23 Protections overload, over temperature, DC short circuit, reversed polarity (fuse) MasterBus compatible yes
