In railway contexts, DC/DC converters are used to reduce the voltage of DC battery packs so that they can be used in various energy and control circuits. This is so that, in the case of a generator failure, batteries might be used to sustain electrical power.
Railway rolling stock has a DC power distribution system for this purpose. To prevent the severe climate from affecting how these converters operate, they must be built in accordance with EN 50155.
The majority of producers of railroad equipment have embraced the EN 50155 – Railway applications – Rolling stock – Electronic equipment standard, which is applicable to electrical equipment supplied to the railway industry.
It covers control, adjustment, protection, and supply applications and applies to battery-powered systems and low-voltage power sources that are directly (or indirectly) coupled to the contact system.
The Global Rail DC-DC converter market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In addition to being UL 60950-1 authorised, TRACO Power Railway and Transit DC/DC Converters are certified to EN 50155 and EN 61373 standards. These converters also hold UL 508 certification for stringent industrial requirements, and certain product families in the TEQ series also carry IEC/EN/UL 60950-1 certification.
The range of products includes 20W to 300W for chassis-mount types and 3W to 240W for PCB-mount units. These converters provide continuous input ranges that operate above the EN 50155-defined input voltage ranges. Galvanic isolation for the DC/DC converters is up to 2250VDC (input to output or input to the case).
