R Series

Share

The ER/HR Series of DC-DC converters represents versatile power supplies ideally suitable for use in transportation and other advanced electronic systems. The HR Series converters include a very broad input voltage range, very high efficiency, high reliability, low output voltage noise, and excellent dynamic response to load/line changes. HR converters can be connected to all conventional railway batteries. ER Series converters are optimized for connection to 110 V railway batteries.

Specifications

  • Very high efficiency up to 94%
  • Interruption time 10 ms
  • 5 year warranty
  • 2 isolated outputs: no load, overload, and short-circuit proof
  • Immunity according to IEC 61000-4-2, -3, -4, -5, -6, -8, -9
  • Compliant with EN 50155, EN 50121, EN 45545
  • Extremely wide input voltage range from 12 to 168 VDC in the same converter (HR Series)

Features

  • Class I equipment
  • Shutdown function
  • Inrush current limitation
  • Rectangular current limiting characteristic
  • Parallel operation with active current sharing
  • Input over- and programmable undervoltage lockout
  • Adjustable output voltages
  • All PCB boards protected by lacquer
  • RoHS-compliant for all 6 substances
