The 150-F43NBDD Solid-State Controller is manufactured by Allen-Bradley under the SMC Flex series. The module comes with an open enclosure and features 43 Amps, 30 Horsepower at 460 Volts AC controller ratings. The 150-F43NBDD’s rated voltage is 200 to 480 Volts AC for the input line voltage. The control voltage is 100 to 240 Volts AC which translates to 5 to 480 Amps Units. 150-F43NBDD SMC flex module is used to operate the standard 3-phase squirrel cage induction motors. It also operates the Wye-Delta (6-Lead) motors efficiently. The soft starter comes in combination and non-combination models. Each 150-F43NBDD controller features has seven standard start modes that are used to control the resistive loads. In addition, it also comes with an LCD feature that makes operating the 150-F43NBDD easier. In addition to the LCD, there is a keyboard that is programmable and comes with ready software. The LCD and programmable keyboard indicate that the 150-F43NBDD is easy to use, especially when being configured for an industrial setting.

The Allen-Bradley 150-F43NBDD provides excellent progressive features. It has a compact style and it comes with an optional enclosed controller. The enclosed 150-F43NBDD controller starts standard three-phase squirrel cage induction motors as indicated above. The 150-F43NBDD can be used to start and stop motors that have up to 6000 Horsepower. The 150-F43NBDD meets the international standards and is designed for the uncomplicated initial installation and setup. It is an easy to use SMC flex, especially in industrial settings. The 150-F43NBDD includes up to nine start and stop modes and it comes with three slow-speed modes. The nine 150-F43NBDD start and stop modes include the Soft Start, Current Limit Start, Dual Ramp, Full Voltage, Linear Speed Acceleration, Preset Slow Speed, and the Soft Stop.  As a safety feature, the 150-F43NBDD comes with built-in electronic motor overload protection. It also provides a built-in silicon-controlled rectifier to bypass the contractor. A pump control is also used to help in the reduction of fluid surges in the centrifugal pumping systems.
