Regarding EN50155 railway certificated power conversion products, Cincon offers a wide range of selections from 8W to 600W.

In general, you need to check and confirm:

1. The Dc-Dc Power Supply product has EN50155 certification.

2. Consider if the input voltage is wide enough to cover multiple voltage requirements in a railway system.

3. See if there is any module for convenience to save your cost and time.

1. EN50155: 2017
 
All products comply with the 2017 edition, the latest version of the railway standards. Many of the changes which are more comprehensive and stricter when compared to the EN50155: 2007 edition.
The changes include the following critical items: operating temperature, relative humidity, battery voltages, interruptions in supply voltage, supply voltages for rolling stock powered by combustion engines, reliability, useful life, capacitance to ground/earth, PCBs,protective coatings, type testing, dry heat thermal test, and voltage withstand test.
With so many changes, Cincon’s Railway DC/DC converters bring you the most updated design compliant with the latest standard.

2. Wide Input Range:
 
One of the advantages of a wide input DC converter, is that rather than buying and stocking multiple products, one can cut cost and inventory by using a single product that supports the various voltage requirements in the railway system.
 
The table below shows the voltage specified in EN50155 and the input voltage covered Cincon Railway DC/DC converters:

3. CMFC/CMFD Plug-in Chassis-Mount Module:
 
The modularized Plug-in Cincon CMFC/CMFD series is a value-added series which could help you in solving the unpleasant EMC issues.
Cincon also offers a detailed application note as the guideline tool to reduce your development time.
