Bahntestanlage 16 2/3 NEtz Beispiel DB20K/200 High voltage power supplies of the types DB20K / 300 have been specially designed for the supply of loads in the 162/3 Hz railway network. The devices are typically manufactured with output voltage up to 25,000 volts and output power from 10kVA to 1MVA.

The main application areas are:
  • Testing of railway systems and equipment
  • Simulation of overhanging contact wire
  • Feeding into local contact wire voltage networks
  • in two containers for outdoor installation
  • Connecting the container from below
