Matrix Filter Series D Over Current Applications


A properly selected Matrix Filter may be used in constant torque AC drive and DC chopper drive applications with six pulse rectifier input circuits. At rated speed, a constant torque drive may deliver 150%-200% of rated horsepower depending on the equipment selected. This results in increased line current of nominally 150%-200% of rated and depending on the application may result in RMS current requirements greater than that available from a Matrix Filter with the same horsepower rating as the drive.
