The Allen-Bradley 150-F135NCDB SMC-Flex Smart Motor Controller is a solid-state controller with an open enclosure type. The input line voltage on the 150-F135NCDB Controller is 200 to 600 Volts AC, 3-Phase voltage, at 50 to 60 Hertz, while its control voltage ranges between 100 and 240 Volts AC. The standard modes of operation include the soft start, selectable kickstart, current limit start, dual ramp start, full voltage start, linear speed acceleration, preset slow speed, and the soft stop. Features on the 150-F135NCDB Smart Controller include a built-in SCR Bypass/Run Contactor, built-in electronic motor overload protection, CT on each phase, metering, DPI communication, an LCD, keypad programming, and 4 programmable auxiliary contacts. Optional features on this SMC-Flex Smart Controller include pump and braking control.

The functional design specifications on the 150-F135NCDB Controller include power wiring using a standard squirrel-cage induction motor or a Wye-Delta, 6-lead motor, as well as 2-and-3-wire control for control wiring. The keypad controls a backlit LCD, and with its software, the parameter values can be downloaded to the SMC-Flex Controller with the DriveTools programming software. Metering can be measured in Amps, Volts, Kilowatts, kilowatt-hours, megawatts, megawatt-hours, elapsed time, power factor, and motor thermal capacity usage. The operating temperature on the 150-F135NCDB Controller should range between -5 and 50 degrees Celsius (open) and -5 to 40 degrees Celsius (enclosed). The storage temperature should range between -20 and 75 degrees Celsius, and the altitude of the machine at operation should not exceed 2000 meters or 6560 feet. Humidity should range between 5 and 95% (non-condensing), and the 150-F135NCDB Controller has a pollution degree rating of 2.
