Converter can be used in various applications

Key figures

  • ultrawide input voltage range: 29 ... 170 VDC
  • very high efficiency: up to 96%
  • peak input voltage: 190 VDC
  • output voltage / max. output current: 27.0 VDC / 13.0 ADC


H-version of the DC transformer with the input voltage range extended to the top. Can be operated continuously at 170VDC and can handle peaks up to 190V. This custom version has been adapted to 27VDC output voltage. This DC-DC voltage converter with 350W output power is currently the most powerful device.
