Traction Rectifiers

Air cooled Diode Coet Traction Rectifiers is designed for Train Lines, Metro Lines and Tram Lines. The range is completed with complete line of inverters and bidirectional converters, using thyristor, IGBT or GTO, to comply with the recent requests of braking energy recovery, Traction converters are fully comply with IEC or ANSI/IEEE standards and the most severe standards for heavy traction service. 

When used Coet Traction Rectifiers, low losses, low operating temperatures, reduced maintenance and noise are granted by the specific design of the power section.
