Murata Power Solutions IRH series DC-DC converters

Murata has launched its latest encapsulated DC-DC converters, designed specifically for use in industrial and railway applications. The 150W IRH series provides market-leading power conversion efficiency, in an industry-standard half-brick pinout, using the latest component and packaging technologies in a fixed-frequency switching power supply architecture.

Features

• 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 96VDC and 110VDC
• Topology supports a pre-biased output at start-up, eliminating the reverse currents during system start and shutdown that can damage critical circuitry 3:1 Vin range of 57.6VDC to 160VDC
• Delivers 5Vout, 12Vout 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 5Vout, 89.5% at 12Vout and 89% at 24Vout
