Electronic equipment used on rolling stock is expected to have a very long operational life of up to 20 years, therefore the environmental testing should be thorough. Besides the normal operating temperature tests, additional thermal cycling, dry heat and damp heat testing is specified. Only a fully potted or sealed DC/DC converter can meet these requirements. As for rolling stock applications; vibration, shock and bump testing is also important. Here it is important to know the location of the final equipment – whether it is mounted in the driver’s cab or inside the passenger wagons or more exposed on the undercarriage or bogies. Smoke is more hazardous in a confined environment such as a train than fire, so the component parts used in the DC/DC converter must not only be self-extinguishing but must also be low-smoke. RECOM sells fully certified DC/DC converters, so besides EN50155 and EN50121-2-3 certificates, our railway converters have also been evaluated to EN45545-2 for their behavior in a fire.
