Products: DC Transformers - Overview

Demke Electronic’s DC-DC transformers are switched-mode power supplies for toughest industrial environments.

Key features of all our products are efficiency, wide input voltage range and minimized EMC emission.

More power, less noise!

Our offer includes switched-mode power supplies in a variety of housings:

  • PCB mounted
  • Wall mounted

Applications for our DC-transformers preferably are battery powered systems demanding a stabilized, controlled on-board grid, as well as generation of a point-of-load voltage supply in microcontroller systems.

These kinds of systems typically are used in wind power, communication systems, battery charging and mobile material handling.

Demke's high power transformers (small and large-scale production), are preferably applied in passenger and goods transportation, both in vehicles as well as traffic control systems.

Project specific development know-how and production of non-grid high performance DC-transformers, individually tailored to the demands and application profiles of our industrial customers, is one of our key assets.

When presenting our products, we are using a set of icons that will help you to get a quick insight into the individual converter’s field of use.
