Winding goods for test systems and test stations

Equip your calibration plant

Are you looking for load reactors, test field transformers, high current transformers or isolating transformers for a test system, a function tester, an automatic assembly machine or a calibration system? Then you have come to the right partner.

Reliable testing on test benches

We offer winding goods for electrical test systems, test benches, test systems, test systems, test equipment, non-rotating inductive loads for converter testing and motor substitute loads. No matter whether for large test fields or smaller test systems.

Standards for test systems

All our products comply with the following standards:

  • Construction and testing standard DIN EN IEC 61558
  • UL/CSA
  • Electrical protection classes I and II
  • Insulation classes B, F and H
  • Protection classes according to IP
  • DIN ISO 9001:2015

Highest demands on reliability

Transformers and chokes for use in test fields and test facilities worldwide are constantly being further developed to meet the requirements of e.g. electromobility test technology. It goes without saying that our products meet the highest standards of electrical safety and reliability.
