Murata Encapsulated DC-DC converters "IR Series"

Murata is introducing its latest encapsulated DC-DC converters designed specifically for use in railway applications.

The IR series (IRH and IRQ series) provides market leading power conversion efficiency in an industry-standard half/quarter brick pinout, allowing system designers to choose the most effective solution for cooling and power delivery.
The IRQ series offers high output current (up to 20 Amps), delivers fixed DC output voltage up to 100 Watts (24V @ 4.2A) and has wide range inputs of 57.6 to 160 Volts DC (110 Volts nominal).
The IRH series offers high output current (up to 30 Amps), delivers fixed DC output voltage up to 150 Watts (5V @ 30A) and has wide range inputs of 57.6 to 160 Volts DC (110 Volts nominal).
