Static Converter Kiepe BNU 500

The converters of the type Kiepe BNU 500 are static converters which are used for the auxiliary power supply in mass transit vehicles. Usually, the vehicles are equipped with a three-phase AC-voltage-system and a DC-voltage-system.

They are designed especially for the mechanical and electrical loads produced by mass transit vehicles. The Kiepe BNU 500 can be fitted on the roof or under floor in a container. Moreover, it can be fitted inside cabinets in the car.

Outstanding features of the Kiepe BNU 500:

  • Simple maintenance
  • Double electrical isolation between input and output
  • Designed for application in rail vehicles and trolleybuses
  • Low-noise
  • High efficiency
  • Low weight thanks to high-frequency switching technology
  • Microprocessor control
  • Diagnostic interface and vehicle bus interface


The new Kiepe BNU 500 series replaces the former on-board converters of the series Kiepe BNU 400. Important innovations are the use of high-frequency switching technology and the reduction of the weight in a increased total output. Furthermore, the construction is simplified and diagnostic capabilities expanded.
