The Allen-Bradley 150-F135NCDB SMC-Flex Smart Motor Controller is a versatile solid-state device designed with an open enclosure, offering robust performance for three-phase systems within the 200 to 600 Volts AC range at 50 to 60 Hz. It features advanced control options such as soft start, current limit start, dual ramp start, and soft stop, with a control voltage range of 100 to 240 Volts AC. This smart controller is equipped with a built-in SCR bypass/run contactor, electronic motor overload protection, detailed metering, and DPI communication, all navigable via an LCD and keypad. Suitable for both squirrel-cage and Wye-Delta motors, it ensures accurate metering of key metrics like voltage, current, and energy consumption, while maintaining operational integrity across a broad temperature and humidity range, and supporting an altitude of up to 2000 meters.
