DC-DC converters deliver high reliability for railway and industrial applications

Murata is introducing the first in a series of encapsulated DC-DC converters designed specifically for industrial and railway applications. The IRQ series delivers the latest technology in fixed frequency power conversion available in the industry. The advanced electrical and mechanical design of the IRQ series modules provides high reliability power conversion in the most demanding rail and industrial applications. The industry-standard quarter brick offers packaging and pin configuration options that allow the system designer to choose the most effective solution for cooling and power delivery. Additional features include On/Off control options, reinforced insulation, 3KVDC isolation, and options for mounting a heat sink or cold wall application. The series delivers fully regulated DC outputs of 5VDC, 12VDC, or 24VDC at 100W. The converters’ 3:1 wide input range of 57.6VDC to 160VDC meets the requirements of EN50155 for nominal Vin voltages of 96VDC and 110VDC including brownout and transient conditions. Each module is designed to deliver full power with efficiencies reaching 87% at 12Vout. With their encapsulated design, the company’s converters are shock and vibration tolerant, and offer improved EMI and excellent thermal performance. Standard and flanged baseplate options offer improved thermal management for many applications. The series power modules are ideally suited for applications in railway systems and industrial applications that require power conversation from either 96VDC or 110VDC bus voltages.
