DC/DC Converters Hit The Rails

Murata’s encapsulated dc/dc converters are designed specifically for use in industrial and railway applications. The 150W IRH series comes in an industry-standard half-brick pinout, using the latest component and packaging technologies in a fixed-frequency switching power supply architecture. Features include:

  • 3:1 Vin range of 57.6 Vdc to 160 Vdc
  • Delivers 5V, 12V or 24Vout with 3,000Vrms input to output isolation
  • Designed and tested to meet the requirements of EN50155
  • Available with standard and flanged baseplate options, and with DOSA or alternate industry standard pinout options
  • Standard features include on/off logic control and protection against short circuits, overvoltage and over-temperature
  • Efficiency ratings of 91% at 5 Vout, 89.5% at 12 Vout and 89% at 24 Vout
  • Encapsulated circuit design makes them shock- and vibration-tolerant and improves EMI and thermal performance
  • Meets the requirements of the EN50155 standard for railway applications for a nominal Vin of 96 Vdc and 110 Vdc
  • Topology supports a pre-biased output at start-up, eliminating the reverse currents during system start and shutdown that can damage critical circuitry
