RECOM offers a broad portfolio of EN50155-certified DC-DC converters for the railway industry, supporting loads ranging from the lowest at 8W to the highest at 240W.

The RPA series includes space-saving converters rated for loads of 20W and 30W housed in a 1” x 1” case. The series also includes a 60W-rated converter in a 2” x 1” case, giving it a very high power density of 4.5W/cm3. For applications requiring the highest thermal performance, RECOM also offers the 20W RP20-FR and 40W RP40-FR in a 2” x 1” case.

These regulated DC-DC converters feature a wide 4:1 input- voltage range. Specially aimed at railway applications, the converters can withstand use in harsh environments such as those found in rolling stock.

Since they are UL/cUL60950 certified, they are also a reliable choice for industrial and telecoms applications.

Single outputs of 3.3V, 5V, 12V and 15V are available, as well as dual ±12V and ±15V outputs. The Control pin logic can be positive or negative at the designer’s discretion.

Offering efficiency up to 93%, these converters can often be cooled by natural convection alone; if required, the modules may also be supplied with a mounted heat-sink.
