Wide input converter targets distributed power needs

The MGDD range dc/dc converter targets distributed power architecture where variable input voltages for multiple battery and transients are prevalent. This makes them suitable for transportation /railways, compatible with EN50155 and RIA12 or for defence and airborne applications, specifically for 28 Vdc applications complying with Mil-Std-1275E.

With  the 20W and 60W standard models featuring a 12 to 160 V input voltage range compatible with 24, 28, 36, 72, 110, and 125-V bus applications. Offering fixed switching frequency of 270Khz the modules also include a soft-start, an input undervoltage lock-out, permanent short circuit protection, thermal protection and output overvoltage limitation protections. The short circuit protection completely protects the modules against short-circuits of any duration by a shut-down and restores to normal when the overload is removed.

Other features include; dual isolated outputs at 2 x 5V, 12V, 15V or 24V. Isolation of 1500Vdc between input and output and no optocoupler ensuring high reliability, all in a 3” x 2” package size.

Gaia Converter is a global leader in field proven high reliability DC power modules. With over 3500 part numbers, its DC-DC Converter, PFC Front End and related input protection product lines offer all necessary building bricks for complete modular High Reliability power supply architectures, from 4 to 350W or more. Its global presence in 25 countries around the world through subsidiaries and local distributors ensures strong technical and sales support near you.

Founded in 1993 near Bordeaux, France, all our products are manufactured there; so ensuring ITAR free components. All products are manufactured within fully automated integrated assembly lines. From the very beginning with pick and place SMD operation to the final automated potting and test operation there is no manual operation and cycle interrupts which guarantees full repeatability and control. Internally controlled processes and automation ensures repeatable high quality products in a timely fashion, reducing lead-times and product field failures.

This integrated assembly line include state of the art equipment :

  • Pick and place SMD Line
  • Infra red reflow oven
  • Automatic potting
  • Automated test equipment


We are refining the source of power exclusively in rugged environment applications and bring to the market our well known concept of Modular Power Architecture to simplify the design of complex power supplies.
