The Allen-Bradley 150-S108NUR smart motor controller is a microprocessor-based solution from the SMC-50 series, designed to optimize motor starting and stopping efficiency. This three-phase soft starter boasts built-in overload protection and controlled rectifiers, allowing precise management of conduction time and voltage during startup, operational phases, and shutdown. With an internal bypass capacity of 108 Amps and a voltage range of 200 to 690 Volts AC, it accommodates both normal and heavy loads with operational frequencies between 50 and 60 Hertz. The controller provides advanced functionalities such as 17 start/stop modes, including soft start and torque control, three slow speed modes, and smart motor braking for enhanced application versatility. It operates within an ambient temperature range of 0 to 50 degrees Celsius and can function at altitudes up to 2000 meters without derating, making it ideal for diverse industrial environments.
