High voltage supply with AC-Output


Unique Selling Point

  • Testing of AC and DC current converters with one unit
  • Constant residual ripple over the entire adjustment range of the DC output
  • Clean sine wave of the AC output voltage
  • No EMC problems
  • Control error approx. 1 % for AC and DC outputs
  • Fast regulation of voltage variations
  • Outputs protected against short-circuit and overload
  • Doubled output current at half the DC voltage selectable
  • True rms measurements with the digital meters
  • System operation possible by means of a control panel not in the immediate vicinity of the HV supply unit
  • Grounding possibility provided for the DC output
  • Additional control of supplementary equipment possible via the control panel



The high-voltage supply unit is intended for testing current converters in the energy sector, as well as testing the entire auxiliary converters and switched power supply systems used in railway installations.
