Three-phase AC power supplies


The three-phase power supplies with economy winding regulate the output voltage with an accuracy of approx. 1.5% of the final value. Switchable voltage ranges of the output voltage ensure a low short-circuit voltage. The transformers are dimensioned according to the existing harmonics of the test objects so that the voltage drop of the harmonics influences the sinusoidal shape of the output voltage as little as possible. Suitable for testing frequency converters and motors according to DIN EN IEC 60034.

The three-phase and single-phase power supplies with separate windings have a variable single-phase output voltage and 16 2/3 Hz mains frequency. The REO sine filter ensures a clean output voltage. The output voltage can be regulated to approx. 1% using the electronic voltage control. For testing railway applications


  • No harmonics
  • No EMC interference
  • Clean sine shape

Other voltages and services can also be offered after consultation. In addition, different operating options / operating concepts and industrial interfaces are possible.
