The 150-F5NBDB controller is an Allen-Bradley solid-state Smart Motor Controller (SMC) or small soft starter with a current rating of 5 Amps and 3 Horsepower of output power. The operating voltage of this device is 460 Volts AC. By using this smart motor controller, small motor control application systems can be upgraded from older electromechanical motor starting systems composed of circuit breakers, contactors, and overload relays to new motion control starting systems composed of just circuit breakers and soft starters. The Allen-Bradley 150-F5NBDB Smart Motor Controller provides the motor circuit activation function of a normal contactor and combines it with several other current limiting and energy-saving capabilities that are not available in older devices.

The operators of the Allen-Bradley 150-F5NBDB Smart Motor Controller can adjust several of its parameters using a 2-line, 16-character retro illuminated liquid crystal display (LCD) screen and a simple programming keypad. External control is made possible within a voltage range from 100 to 240 Volts AC, and this enables the Allen-Bradley 150-F5NBDB Smart Motor Controller to receive commands from both 110 Volts AC and 220 Volts AC rated signals. Optional interconnection with the plant’s control algorithms is also possible with an additional communication module that is available from the Allen-Bradley Bulletin 1203 product line. This additional module enables the starting and stopping of the soft starter from the machine’s programmable logic controller, providing the users with a higher level of integration between the different parts of the machine. Given its open construction type, this smart motor controller should always be installed inside a protective enclosure.
