Mastervolt DC-DC Converters - Mac & Magic For 12V, 24V & 48V

The voltage required for direct current (DC) can vary considerably onboard a yacht. A bowthruster or a winch often works at 24V, while navigation and communication equipment mostly requires 12V. By using a DC-DC converter, other voltages than applied in your basic system can be reached. They also ensure that all your onboard equipment has a stable power supply with the right voltage.

Mac & Magic series
• Professional use
• Battery charger and dimmer function
• Parallel connection
• Adjustable output voltage
• Voltage stabilisation for a longer lifespan of halogen lights, etc.

The Magic 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.

Programmable via a 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.

3-Step battery charger
Connected to the 24V main battery, the converter can also be used as advanced 3-step chargers for 12/24V gel, AGM, wet or Lithium Ion batteries (Mac and Magic models only).

• No unnecessary heat development due to the use of smart electronics
• Continuous output voltage
• Easy to install

Please note:
• Choose the right input/output voltage
• Do you require galvanic isolation?
• Desired capacity

Energy-saving dimmer function
Many standard light dimmers convert part of the energy to heat and also lose unnecessary energy. The Mastervolt Mac and Magic converters regulate the power supply efficiently and without excessive heat build-up, up to 250 Watt for optimal safety (multiple Mac or Magic converters can be used for multiple lamps).

Solid connections
Chrome plated brass connection block with screw terminal or chrome plated fast-on for DC in/out.

Over 90% efficiency
Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12V and vice versa. If you have many power consuming devices on-board, the parallel use of several units allows capacities of 40, 60 or more amps.

Complete package DC Master
All DC Master converters are supplied with mounting bracket, screws and fasteners.
