Power supply manufacturer RECOM, has announced the release of its latest RPA40-FR series of rugged, board-mount DC/DC converters, specifically designed for use in railway and industrial applications. With a wide input range of 36-160VDC and a reinforced isolation rating of 3kVAC/1min, the RPA40-FR series is suitable for use in harsh environments, where surge voltages and high temperatures may be encountered.

The RPA40-FR series is highly efficient, with peak efficiency of up to 90%, allowing for full load output to high ambient temperatures with natural convection cooling only. Furthermore, advanced thermal design enables operation in ambient temperatures of up to 105°C, with load derating and/or airflow. What's really impressive about these converters is their wide input voltage range of 36 – 160VDC, which covers nominal input voltages of 72V, 96V, and 110V with tolerances, dips, and surges. This flexibility makes them suitable for a variety of applications, especially in harsh environments where surge voltages and high temperatures might be encountered.

As far as certifications go, the RPA40-FR series holds safety certifications to UL/EN/IEC 62368-1, EN 45545-2, and EN 50155, and features a reinforced isolation rating of 3kVAC/1 min. The series meets EN 55032 class A EMC specification without external components, and can meet class B with the addition of a simple filter. The MTBF for the parts is 1.25MHrs according to MIL-HDBK 217-F (GB/25°C), making them a reliable choice for any application.
