Since 1999 SMA has been delivering multi-voltage auxiliary power supply systems for railway coaches based on the MEE-NT platform.Vehicles with an MEE-NTLD system are approved in almost all European countries and are characterized by their high reliability.

Introduced in the winter of 2005, the MEE-NTLD multi-voltage auxiliary power supply has made the famous Venice Simplon-Orient-Express even more comfortable. The power supplies, which are each installed in two separate compact underfloor enclosures, are
extremely reliable and quiet.

But this is only one application. The converters are also used in couchette coaches, sleepers or day coaches of e.g. German Railways (DB), Austrian Railways(ÖBB), CityNightLine and Danish State Railways (DSB).
