The SMC Plus series is a series of Allen-Bradley smart motor controllers. The SMC Plus series features units that are developed to ensure application scalability and they are built to ensure minimal energy costs. They feature simple controls for application starting and stopping. The SMC Plus controllers are performance models that come with motor protection and ensure an easy programmability process. The SMC Plus series controllers come with a line voltage that ranges from 200 to 600 Volts and they are available in enclosed and open designs. These controllers have different models that effectively control different motors with varying Horsepower and current values.

The SMC Plus motor controllers are designed to provide various operation modes. These include the soft start with selectable kickstart, the current limit start, the dual ramp start, and the full voltage Start. The SMC Plus series controllers feature undervoltage protection. The undervoltage protection feature ensures that the SMC Plus controllers have the ability to halt motor operation if there is a drop in the incoming line voltage. To ensure the elimination of nuisance trips, the SMC Plus controllers feature programmable undervoltage trip delay times. The SMC Plus controllers also come with the current sensing capability that is disabled during the bypass operation. These units also support the SMC dialog plus controllers for allowing the users to program the allowed number of starts per hour. The SMC Plus controllers feature motor thermal capacity use that allows the users to easily monitor the amount of overload thermal capacity. The SMC Plus controllers also support a built-in SCANPort communication option.
