Eaton Corporation’s SPX drive is an adjustable-frequency drive for controlling the speed of industrial motors. The SPX400A0-5A4B1 is rated at 400 hp and specified for 525–690 V, with an open-chassis construction and an internal brake chopper. The drive varies motor supply frequency to regulate speed, while the brake chopper supports dynamic braking by controlling energy flow to a braking resistor. It is intended for industrial motor-drive installations where variable-speed control and braking are required.
