Abstract
A modular motor controller family comprises a housing. Solid state switches are selected from one of plural switch sizes for controlling a desired voltage and current range. The switches are mounted in the housing for connection between an AC line and motor terminals for controlling application of AC power to the motor. A logic circuit board is mounted in the housing including logic circuitry for commanding operation of the solid state switches independent of the selected switch size. An interface circuit board selected from one of plural configurations is mounted in the housing and includes interface circuitry connected between the logic circuitry and the solid state switches. The interface circuitry is selected to interface with the selected switch size according to the desired voltage and current range.
