Mastervolt Magic DC Converter 24 Volt – 24 Volt 20 Amp 81300200
Mastervolt DC DC Converters Mac Magic 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 those 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 Features
- Professional use
- Battery charger and dimmer function
- Parallel connection capability
- Adjustable output voltage
- Voltage stabilisation for a longer lifespan of halogen lights and other sensitive equipment
The Magic models can regulate the voltage both up and down to ensure optimal voltage stabilisation even when the battery voltage fluctuates due to heavy loads. The galvanic isolation between input and output prevents disruptions to sensitive equipment such as communication devices.
Programmable via a desktop or laptop PC. You can remotely control the Mac or Magic via your computer or configure your personal preferences. The device includes a communication port and easy installation with PC Link and MasterAdjust software.
3 Step Battery Charger
Connected to the 24 Volt main battery, the converter can also be used as an advanced 3 step charger for 12, 24 Volt gel, AGM, wet or Lithium Ion batteries (Mac and Magic models only).
Masterstrokes
- No unnecessary heat development thanks to smart electronics
- Continuous output voltage
- Easy to install
Please note:
- Choose the correct input and output voltage
- Check if galvanic isolation is required for your setup
- Consider the desired capacity
Energy Saving Dimmer Function
Many standard light dimmers convert part of the energy to heat and lose unnecessary power. The Mastervolt Mac and Magic converters regulate the power supply efficiently and without excessive heat build up, up to 250 Watts. 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 input and output.
Over 90% Efficiency
Advanced high frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12 Volt and vice versa. If you have many power-consuming devices onboard, the parallel use of several units allows capacities of 40, 60 or more amps.

Boat Hut Insight
When choosing a DC converter like the Mastervolt Magic, consider not just the voltage and current ratings but also how often you’ll need to adjust the output voltage for different devices onboard. If you’re someone who likes tinkering or upgrading your boat’s electrical system frequently, the programmability via laptop is a huge bonus — it’s like having a smart assistant for your power needs. Also, don’t underestimate the value of galvanic isolation; it’s a small feature that can save you from frustrating interference issues, especially with sensitive navigation and communication gear. And a quick tip: if you’re planning to add more power-hungry devices later, buy a model that supports parallel connection to avoid costly upgrades down the track.
