1/16th brick DC/DC converters for industrial and railway applications

Murata has launched its latest in a series of encapsulated DC/DC converters designed specifically for industrial, industrial mobility and railway applications. The 50W IRS-Q48 series from Murata Power Solutions provides market-leading efficiency using the latest technology for fixed frequency switching power supply architectures, in an industry standard 1/16th brick pinout. Murata’s IRS-Q48 series provides basic insulation with 2250VDC input-to-output isolation and a fully regulated DC output.

The IRS series includes modules with outputs of 3.3, 5 and 12 VDC with up to 50W of output power. The universal Vin range of 18 – 75VDC meets the requirements of EN50155 for nominal input voltages of 37.5VDC and 48VDC including brown out and transient conditions.

The IRS-Q48 series is available with an option for a standard or a flanged baseplate for various conduction cooling configurations including cold wall mounting. With an efficiency of 91%, the converters operate cooler and more efficiently.

The electrical and mechanical design incorporates proprietary technology providing shock & vibration tolerance that meets or exceeds EN 61373:1999 Category1, Class B, Body Mounted requirements.

With its wide 4:1 input range, the IRS-Q48 series supports common bus voltages of 24 V, 28 V, 37.5 V, 48 V & 54 Vdc commonly found in industrial, industrial mobility and rail electronic systems.

Applications for these converters will be in the rail eco system including, but not limited to mobile communications signalling, lighting, signs, computing, motor drives, control modules, and security systems.

Other applications include 12V, 24V & 48V battery systems, smart grid systems, intermediate bus, harsh environment applications in networking equipment, wireless networking equipment for mobile computing, test equipment, and other applications requiring a regulated 3.3, 5 and 12VDC source.

Standard features of the series include baseplate cooling, encapsulated mechanical design, on/off logic control, output short circuit & overvoltage protection, along with, input under voltage lock out (UVLO) over temperature protection circuits.

The IRS-Q48 incorporates the latest fixed switching frequency technology for power conversion available today, and the optional packaging configurations, safety features, efficiency and high reliability offer an unmatched level of performance.
