CP traction power rectifier units are AC to DC Power Converters designed for subway, light rail, and other transit system applications. All CP traction power rectifiers are natural convention, air-cooled power silicon assemblies. Silicon diode rectifiers have been field proven over a number of years for greater equipment reliability and overload capabilities.

CP traction power rectifiers deliver 6 or 12 pulse direct current. The equipment is rated for all NEMA RI-9 traction power ratings. The output voltage of the rectifiers is 600 to 1500 volts dc at 100% full load. The power ratings are up to 5000kW as defined in NEMA RI-9 Extra Heavy Duty.
