Expanded portfolio of DC-DC converters for the railway industry

RECOM has expanded its portfolio of DC-DC converters for the railway industry from 8W to 240W over the years and can now offer the broadest portfolio of EN50155 certified products available on the market. A few newcomers are the RPA20-AW, RPA30-AW, RPA60-FW, RP20-FR, and RP40-FR. RECOMs RPA series packs 20W and 30W in a 1”x1” case and 60W in a 2”x1” case for a power density of 4,5W/cm³ - claimed to be one of the highest available on the market. For superior thermal performance, RECOM also offers the 20W and 40W RP20-FR and RP40-FR in a 2”x1” case. These regulated DC-DC converters with their 4:1 wide input voltage range are especially designed for railway applications. The series are EN50155 certified and designed for use in harsh environments such as rolling stock. Since they are UL/cUL60950 certified, they are also a reliable choice for industrial and telecommunication applications. Besides 3.3V, 5V, 12V and 15V single outputs, dual ±12V and ±15V outputs are available. The control pin logic can be chosen to be positive or negative. With efficiencies of up to 93%, cooling by natural convection is typically all that is needed, but if required, the modules are also available with a pre-mounted heatsink.
