The Allen-Bradley SMC-50 smart motor controller includes a newly designed three-phase, fully solid-state, silicon-controlled rectifier (SCR) power structure. The controller addresses the motor control needs of OEMs and end users seeking a more economical alternative to drives and more advanced control than across-the-line starters. Designed for customer flexibility, the unit combines advanced monitoring and protection features, multiple start and stop options, and expandable control inputs and outputs. These features help users increase efficiency, reduce downtime and improve control. Rated at 200V-690V AC and with software from 90 to 520 amps, the system is ideal for controlling motor speed and torque in a range of normal-duty applications, including pumps, compressors and short conveyors, as well as in heavy-duty applications, such as centrifugal fans and long conveyors.
