Eaton Corporation’s SPX400A1-5A1B1 is an SPX drive rated at 400 HP, with a NEMA Type 1 enclosure, a 525–690 V rating, and an internal brake chopper. As a variable-frequency drive, it regulates the speed of compatible AC motors by controlling their power supply frequency. The brake chopper supports braking by controlling the connection of an external braking resistor to manage energy returned by the motor during deceleration. This drive is intended for industrial motor-control systems requiring adjustable speed and braking.
Precision Electronics, Inc. (PEI) provides industrial repair services for Eaton Corporation SPX drives, including the SPX400A1-5A1B1. Repair support for this high-power motor-control equipment addresses the drive as an integrated system, with attention to its speed-control and braking functions.
