For the toughest tasks

The 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 better

The reliability and long lifespan of Mastervolt’s 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 Heart

As part of our constant search for eco-friendly and long-lasting solutions, Mastervolt has developed the Green by Heart programme. 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 limited.
  • Use of top quality components with a long lifespan.
  • Savings in weight and space.
  • Fewer installation materials.

MasterBus compatible

For 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 centralised monitoring, configuration and operation of your system with a MasterView panel.

Programmable via desktop or laptop/PC

Remote 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 function

Many 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 operation

If 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 supply.
  • For 12 and 24 V battery systems.
  • Parallel switching of multiple units for capacities of 40, 60 or more Amps.
  • Battery charger and dimmer function.
  • Adjustable output voltage.
  • Voltage stabilisation for a longer lifespan of halogen lights, etc.
  • Corrosion-proof aluminium casing.
  • Shock-proof.
  • Temperature-powered fan for cooling.
  • Generates limited heat, so installable almost anywhere.
  • Fully MasterBus compatible with a MasterBus Serial Interface.

 

Magic as power supply

The Magic models can be fully used as a stabilised power supply: From 12 to 24 V, from 24 to 12 V or from 24 to 24 V. Inputs and outputs are galvanically isolated.

 

Mac & Magic as battery charger

12 V starter or emergency power batteries can be charged and monitored by a Mac or Magic converter. The charging method is identical to Mastervolt’s Mass products (3-step technology), and voltage levels are adjustable using the MasterBus PC-Link/MasterAdjust software.

 

Mac or Magic as dimmer

Lights can be dimmed by means of a push button or pulse switch, with a maximum load of 250 watt for the Mac. A second Mac can be installed when using multiple lamps.
