The Allen-Bradley SMC Plus motor controller is a soft starter solution designed for industries that demand high performance, safety, and energy efficiency. Built for rugged applications—from mining and metals to food processing and petrochemicals—it combines flexible starting modes, motor protection, and advanced control features into one compact unit. In this guide, we’ll explore what makes the SMC Plus a reliable choice for automation, including its key features, environmental specs, and most common uses.

Key Features of the SMC Plus

Flexible Starting Modes

Choose from Soft Start, Current Limit, or Full Voltage Starting to reduce torque shock, prevent motor stress, and enable smooth acceleration in various industrial scenarios.

Built-In Motor Protection

Includes pre-start and run-time protection against phase loss, shorted SCRs, and stalls. These protections minimize downtime and extend equipment life.

Energy Optimization

The integrated Energy Saver monitors motor load and adjusts output voltage to minimize energy waste during low-load conditions.

Advanced Control Options

Supports 2-wire and 3-wire control schemes. Features Soft Stop, Smart Motor Braking, and Pump Control to ensure precise speed control and safe stopping.
