The Allen-Bradley 150-SB2NBD SMC-50 Smart Motor Controller is a 460V, 110A soft-starter designed for optimal performance in 3-phase induction motors, featuring solid-state microprocessor control and SCR starting. This advanced controller eliminates the need for an external bypass, utilizing an internal bypass to reduce heat and shrink size, which results in lower operating costs. Equipped with nine starting modes and three expansion ports for versatile connections, this unit integrates effortlessly into existing automation systems via its DPI communication protocol. It offers comprehensive protection features including electronic motor overload, over and under voltage detection, and voltage unbalance protection. Engineered for robust performance, it operates within a voltage range of 200 to 460V AC and withstands temperatures between -20 to 40 °C without the need for de-rating, making it ideal for demanding industrial environments. Additionally, the 150-SB2NBD boasts CE and UL certifications, ensuring it meets high safety and performance standards.
