Product details

The DC-DC MAGIC converter from MASTERVOLT converts one DC voltage into another stabilised DC voltage, with total galvanic isolation between input and output.


  • Stabilised 12VDC power supply / single step trickle charger (e.g. to supply 12V equipment from a 24V system)
  • 3-step battery charger for fully automatic charging of a 12V battery from a 24V system
  • Dimmer for 12V lights
  • 24/36V converter without galvanic isolation, with which the input is connected in series with the output.
  • Continuous capacity of 20 A (270 W)
  • Conversion to the correct voltage
  • Voltage stabilisation leads to a longer service life of halogen lights
  • Battery charging and dimmer function
  • The Magic series are totally interference-free due to the galvanic isolation of input and output.

The device ensures that all your equipment on board receives a stable power supply with the correct voltage.

All devices offered by us are galvanically isolated; this means that any voltage potential differences between the ship's ground and minus on-board power supply are eliminated. Cycle hum, which often leads to poor FM radio reception (especially with car radios), are a thing of the past.

In addition, the Mastervolt DC-DC converters are equipped with a battery charging output. With a 24-volt vehicle electrical system, the Magic 24/12-20 can be used to charge any 12-volt batteries (starter or radio batteries) that may be present. 3-stage IUoUo charging characteristic curve for almost 100% battery charging.
