Trackside auxiliary converter fed by overhead line
KONTRAC PN 50 DC / PN 100 DC
Converter is fed by 3 kV DC overhead line. It is used in order to supply various loads inside the substation facilities (power supply for integrated lighting and information systems, railway signaling and protection systems, etc.). Overhead line might generate spikes, sags and surges caused by the current drawn from locomotives. Those are likely to damage the input stages of conventional converters.
In order to provide a trackside noise filtered power source, we use the same technology as for our rolling stock converters.
The converter is primarily intended to be used as a backup energy source (in case of power outage from the distribution network). However, in projects where poor or no distribution network is available at site, this converter can be implemented as a primary power source as well.
