Power Supplies for the Rail Industry


The global rail industry demands high quality power supplies and DC DC Converters which meet very strict design standards. At CP Power & Automation we have worked within the Rail Industry for many years and have multiple partners who supply directly into the European Rail Industry and beyond.
Some applications which we have worked in are:
  • High efficiency onboard battery chargers, DC DC Converters and auxiliary power supplies
  • Train communication and monitoring systems
  • Passenger Information Systems
  • Onboard power distribution
  • Railway Communications and Signaling
