Description
Mastervolt DC Master Converter 24 Volt – 12 Volt 12 AMP 81500300
Mastervolt DC DC Converters DC Master for 12 Volt, 24 Volt, 48 Volt systems.
The voltage required for direct current (DC) can vary considerably onboard a yacht. A bow thruster or a winch often works at 24 Volt while navigation and communication equipment mostly requires 12 Volt. 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.
DC Master Series
Recreational and semi-professional use.
- Easy to install using included mounting bracket.

- Supplied with mounting bracket, screws and fasteners.
- Programmable via a desktop or laptop personal computer.
- Remote control the Mac or Magic via your laptop or personal computer or configure your personal preferences.
- The device has a communication port and easy installation with a PC Link and MasterAdjust software.
Masterstrokes
- No unnecessary heat development due to the use of smart electronics.
- Continuous output voltage.
- Easy to install 3 Step battery charger.
- Connected to the 24 Volt main battery, the converter can also be used as advanced 3 step chargers for 12, 24 Volt gel, AGM, wet or Lithium Ion batteries (Mac and Magic models only).
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.
Efficiency
Over 90% efficiency. Advanced high frequency technology with modern microprocessors ensures minimum power loss when switching from 24 Volt to 12 Volt 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.
Solid Connections
Chrome plated brass connection block with screw terminal or chrome plated fast on for DC in/out.
Complete Package
All DC Master converters are supplied with mounting bracket, screws and fasteners.

Boat Hut Insight
When considering a DC converter for your yacht, remember that the efficiency rating can make a big difference over time—not just in power savings but in heat management. A converter running cooler means less stress on your boat’s electrical system and potentially longer equipment life. Also, if you’re running multiple devices, think about future-proofing by choosing a model that supports parallel operation, so you can easily add capacity without rewiring everything. And a little tip: if you’re the kind of skipper who loves tinkering, the programmability and PC interface of this converter can turn a routine installation into a fun project—just don’t forget to back up your settings before you start experimenting!
Another point to consider: while these converters boast natural cooling and low noise, installation location is key. Avoid cramped, poorly ventilated spaces—think of your converter like a guest who prefers fresh air and personal space. A well-ventilated spot not only keeps the unit happy but also extends its lifespan, saving you from unexpected breakdowns in the middle of your voyage.
