Mac 24/12-20

The Mac models can regulate the voltage both up and down to ensure an optimal voltage stabilisation, even when the battery voltage fluctuates due to heavy loads. The galvanic isolation between input and output prevents disruptions to, for instance, communication equipment. 

  • Professional use.
  • Converter and 3-step battery charger.
  • Parallel switchable.
  • Adjustable and programmable output voltage.
  • Voltage stabilisation for a longer lifespan of halogen lights, etc.
  • Dimmer function for Mac & Magic models.
  • Mac Plus: optimal charging in Euro 5/6 applications.

The non-isolated Mac models have an electrical connection between  the input and output.
Features:

  • Low costs.
  • Efficient: low heat generation.
  • Compact.
  • Suited to applications with negative earthing.

For the toughest tasks

The Mac 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. 

Programmable via desktop or laptop or PC

Remote control the Mac 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 Mac converters regulate the power supply efficiently and without excessive heat build-up, for optimal safety (multiple converters can be used for multiple lamps).

Parallel operation

Lots of consumers on board? 
The parallel configuration of several units will provide you over 100 amperes. Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12 V and vice versa.
