Railway DC/DC converter expand broad offering

Additions to the RPA series, the RPA20-AW, RPA30-AW, RPA60-FW, RP20-FR, and RP40-FR, extend the range which operates from 8.0 to 240W.


The RPA series delivers 20 and 30W in a 1.0 x 1.0inch case and 60W in a 2.0 x 1.0inch case for a power density of 4.5W/cm³. According to the company, this is one of the highest available on the market. For thermal performance, the 20 and 40W RP20-FR and RP40-FR are offered in a 2.0 x 1.0inch case.


The regulated DC/DC converters have a 4:1 input voltage range and are especially designed for railway applications. The series is EN50155-certified and designed for use in harsh environments such as rolling stock. They are also UL/cUL60950 certified, making them suitable for industrial and telecommunication applications.


Single outputs of 3.3, 5.0, 12 and 15V are available alongside dual  ±12 and ±15V outputs. The control pin logic can be selected to be positive or negative. Efficiencies are up to 93%, meaning that cooling by natural convection is typically all that is needed. If required, the modules are also available with a pre-mounted heatsink.


All models carry the company’s standard, three-year warranty.
