Advanced Energy Industries, Inc. – a global leader in highly engineered, precision power conversion, measurement and control solutions – introduced two rugged DC/ DC converters optimized for demanding railway and other mass transportation applications. The ERM100 and ERM150 series extend the company’s Artesyn™ product line with compact quarter-brick, fully encapsulated 100 W and 150 W options with efficiency levels of up to 91.5%.
With reinforced insulation and high EMC immunity, the ERM100 and ERM150 address the challenging electrical and physical operating environment in railway applications. In addition to using only UL94 V-0 rated flame retardant materials for their packaging, the converters are EN 61373-rated for vibration and thermal shock. A baseplate that is optimized for contact cooling simplifies thermal management, while a heatsink version is available for designs requiring more stringent heat management.
“Railway and other mass transportation applications present requirements in both rolling stock and infrastructure that are often compounded by continuous use over extended time periods,” said Joe Voyles, vice president of marketing, industrial power conversion products at Advanced Energy. “The ERM100 and 150 provide a robust, high efficiency solution for design engineers working in this sector, giving them dependable power in a fully integrated module.”
Both converters have a European Railway Standard EN50155 compliant input voltage range of 36 to 160 Vdc, operate with a fixed switching frequency and deliver a single, continuous power output. The ERM100 and ERM150 have no minimum load requirement and exhibit low ripple and noise characteristics. Operating temperature range is -40 °C to +85 °C.
The high reliability of the RoHS-6 compliant modules is further reinforced by compliance with EN50155 and IEC60671 safety standards. The converters come with a three-year warranty.
