Rail transportation power supplies have been subjected to stringent requirements including transient, energetic spikes and hold up specifications. Traditionally a majority of these power supplies have been developed specifically with discrete components.

The standard input voltages in rail applications are 72 VDC or 110 VDC as in signalling applications. The 24 VDC is a variation described in the widely used EN50155 standard. Fast and energetic spikes are of primarily importance and need to be handled with sufficient protections. The power requirements generally range from 4W up to 200W per board.

To cope with these particular requirements, Gaia Converter proposes typical off-the-shelf modular power architecture :

LGDS series : essential functions such as energetic spike protections and EMI filters according to EN50155, RIA12, IEC571 are provided by standard “limiter” front-end products
MGDI series : for the heart of the power system, Gaia Converter offers a complete series of low profile, cost-effective and high performance DC/DC modules that come in multiple combinations of input voltages, output possibilities and power ratings.

Some of the programs with on board GAIA Converter products are listed below:

 

           Intercity Trains :

           1. TGV-A, KTX, TGV-2N fast train

           2. ICE2 intercity express train

           3. Class 407 Velaros ICE3 fast train

           4. X2000 tilting train, etc.

           Subways/Metros/Trams :

           1. Meteor automatic controlled subway

           2. Citadis verstile tram series

           3. Sirio light rail tram series

           4. Icentro low frour articulated tram, etc.
