Magic 12/12-20 DC ConverterFor The Toughest TasksThe Mac and Magic DC-DC converters are designed for the toughest conditions for professional, semi-professional and recreational purposes. Even under the most extreme conditions, these DC-DC converters operate faultlessly, giving you round-the-clock output when necessary. The sustainability and technologies that underpin the Mastervolt concept have long been proven in practice. With an MTBF of 280,000 hours at full capacity and 24/7 use, the DC-DC converters are ideal for the toughest tasks and any situation that requires a reliable power supply.Making The Best Even BetterThe reliability and long lifespan of Mastervolts DC-DC converters have been established beyond doubt over the past 20 years. While the Mastervolt products have evolved with the latest technological developments, the dimensions and connections have remained the same. As a result it is exceptionally easy to replace one unit with another with only negligible downtime.Mastervolt Green by HeartAs part of our constant search for eco-friendly and long-lasting solutions, Mastervolt has developed the Green by Heart program. Its impact on the Mac & Magic DC-DC converters include:An exceptionally effective use of the consumed input current (cos phi) > 0.98!Faster charging of batteries, even with when the input current is limitedUse of top quality components with a long lifespanSavings in weight and spaceFewer installation materialsMasterBus CompatibleFor the DC-DC converters you can use the MasterBus Serial Interface. All you need is a single cable with one connection. Your benefits: Fast and easy installation, plus centralized monitoring, configuration and operation of your system with a MasterView panel.Programmable via Desktop or Laptop/PCRemote control the Mac or Magic via your laptop or PC or configure your personal preferences. The device has a communication port and easy installation with a PC-Link and MasterAdjust software.Energy-Saving Dimmer FunctionMany standard light dimmers convert part of the energy to heat and also lose unnecessary energy. The Mastervolt Magic converters regulate the power supply efficiently and without excessive heat build-up, up to 580 watts for optimal safety (multiple Magic converters can be used for multiple lamps).Parallel OperationIf you have many/heavy power-consuming devices onboard, the parallel use of several units allows capacities of 40, 60 or more Amps. Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12 V and vice versa.Powerful Selling Points:Reliable and very stable DC supplyFor 12 and 24 V battery systemsParallel switching of multiple units for capacities of 40, 60 or more AmpsBattery charger and dimmer functionAdjustable output voltageVoltage stabilization for a longer lifespan of halogen lights, etcCorrosion-proof aluminium casingShock-proofTemperature-powered fan for coolingGenerates limited heat, so installable almost anywhereFully MasterBus compatible with a MasterBus Serial InterfaceSpecifications:Nominal output voltage: 13.6VOutput voltage (adjustable with MasterAdjust): 10-15VOutput voltage dimmer (adjustable with MasterAdjust): 4-13VOutput voltage stabilization: 2% at extremes of temperatures, load and inputOutput voltage ripple (peak peak): max. 1%Max. output power: 300WNominal output power: 300WMax. output current: 20AOutput charge current (3-step mode): 16 ANominal input voltage: 12VInput voltage range: 11-16VInput voltage range (3-step charge mode): 12-16VLower input set point (adjustable with MasterAdjust): 10VDelay lower input set point (adjustable with MasterAdjust): 30 sec.Galvanic isolation: yesVoltage limited: yesEfficiency: > 90% at nom. input voltage, full load; peak 92 %Dimmer function: yes, by external momentary switch via fast-on connection, to be activated by DIP switch settingAlarm contact: yes (fast-on connector)Dimensions, HxWxD: 227 x 154 x 81mm / 8.9″ x 6.1″ x 3.2″Weight: 1.8kg / 4.0lbApprovals: CE3-Step charge option: yes (DIP switch settings)DC consumption: < 115 mAConnections: screw terminals (max. wire size 16 mm / AWG5)Temperature range (ambient temp.): -25 C to 80 C, derating > 40 C -13 F to 176 FSound level: < 48 dBA at 1MProtection degree: IP21Protections: against over load & over temperatureCooling: maintenance free vario fansMasterBus compatible: yes, in combination with a MasterBus Serial InterfaceWARNING: This product can expose you to chemicals including di(2-ethylhexyl)phthalate (dehp) which is known to the State of California to cause cancer, birth defects or other reproductive harm.
