CVS 280 Series – High Voltage DC DC Converter/ Battery Starter

Relec Electronics proudly announces the availability of CVS-280 series DC-DC Converters.  The CVS-280 series are designed to operate directly from the 750V dc catenary line and can provide dc outputs from 24V to 110V @ 280 Watts continuous & 400 Watts peak power. 

Typically applications include battery start up and control systems in train or tram systems, photovoltaic control systems, subsea electronic modules or electric vehicle projects.

The CVS-280 series have a wide input voltage range from 400-1100V dc and have been primarily designed to support battery starting applications in the railway sector.  It is designed to operate directly from the main 600/750V dc catenary line and meets the requirements of EN50155:2017 (Electronic equipment for rolling stock applications), EN50163:2006 (Railway applications – Supply voltages of traction systems), EN50121-3-2 (Railway applications – electromagnetic compatibility) and EN45535 (Fire protection on railway vehicles).  In addition to the wide continuous input range, the CVS-280 can withstand surges to 3kV dc for 20mS and 4.5kV for 1mS.  Units are available with 24V, 36V, 72V or 110V outputs and can be connected directly to battery terminals for battery charging applications.

The CVS-280 series provides 280W of continuous power with peaks of 400 Watts.  Input to output isolation is 7kV rms and input to earth 5.3kV rms.

Key features of the CVS-280 series are…
