IRx Series Encapsulated Quarter-Brick Isolated DC/DC Converters

Murata Power’s ultra-efficient 1/16th brick DC/DC converters for industrial and railway applications

Image of Murata's IRQ and IRS Series Encapsulated Quarter-Brick Isolated DC/DC Converters Murata's IRQ series regulated converter modules come in an industry-standard, fully encased package and are fully isolated (3,000 VRMS). The IRQ's diode rectifier topology and fixed frequency operations provide excellent efficiencies. Multiple options of this series include various pin lengths and flanged baseplates. The IRQ series accept a 57.6 VDC to 160 VDC input voltage range with a reinforced insulation system.

The IRS series offers high output current (up to 15 A) in an industry-standard sixteenth brick. The IRS series delivers fixed DC output voltage up to 49.5 W (3.3 V at 15 A) for printed circuit board mounting. The wide input range of 18 VDC to 75 VDC (48 V nominal) are ideal for industrial and railway applications.

The IRH series offers high output current (up to 30 A) in an industry standard half brick. The IRH series delivers fixed DC output voltage up to 150 W (12 V at 12.5 A) for printed circuit board mounting. Wide input range of 57.6 V to 160 VDC (110 V nominal) are ideal for industrial and railway applications.
