18 years ago, ed-k was the first manufacturer to develop and manufacture a commercial inductance measuring device based on the pulse measuring principle. Since then we have been the technological leader in this field.

Our Power Choke Tester DPG10 series has established itself worldwide as a standard for the development, production and quality control of inductive power components since many years. Our devices are in service in 35 countries on 4 continents.

Our customers include international concerns (ABB, Siemens, Schneider Electric, Danfoss …), renowned manufacturers of electronic components (TDK-Epcos, Würth, Sumida, Murata, VAC, Vishay, Schaffner EMV …), manufacturers of drives for industry, railway and elevators (Bombardier, Knorr Bremse, Kone, Schindler, Thyssen …), manufacturers of core materials (DMEGC, Hitachi, CSC, Magnetics …) and welding equipment, many development divisions of power electronics (Bosch, BMW, Conti, ZF, Delta, Schaeffler, Hella …), universities and numerous medium and small sized coilwinding manufacturers.

The following list is only a small section of our manifold customers.
