The 150-F201NBDB, produced by Allen-Bradley, is a sophisticated motor controller in the SMC Flex series. This solid-state device works with both Line and Delta connected motors, handling up to 201 Amperes and delivering 150 HP. It offers various operation modes including Soft Start, Current Limit Start, Selectable Kickstart, Coast-to-rest, Soft Stop, Full Voltage Start, Dual Ramp Start, Pump Start, Preset Slow Speed, Pump Stop, Smart Motor Braking, Accu-Stop, Slow Speed with Braking, and Linear Speed Acceleration using a Tachometer.
The 150-F201NBDB is compatible with standard squirrel-cage induction motors as well as Wye-Delta, six-lead motors. It features a keypad and LCD display for local operation and configuration, and provides two DPI communication interfaces for connecting optional Human Interface Modules (HIM) or other DPI-enabled devices. The controller includes auxiliary functions for measuring metrics such as Amps, Volts, kW, kWh, MW, MWH, elapsed time, and power factor, along with motor thermal capacity parameters. It offers status indications for stopped, starting, stopping, at-speed, alarm, and fault conditions, and incorporates an alarm relay for alerts on overload, underload, undervoltage, overvoltage, unbalance, jam, stall, and ground fault conditions, which can be wired to external monitoring devices.
This solid-state Smart Motor Controller combines the functionalities of a contactor and an overload switch. Additional protection against short circuits can be achieved by adding a motor circuit breaker. The compact size of the 150-F201NBDB saves panel space and simplifies inventory, maintenance, and troubleshooting, making it an excellent replacement for older electromechanical devices. The energy-saving operation modes, high current rating, and broad voltage range (200 to 460 Volts AC input, 100 to 240 Volts AC control) make it suitable for numerous industrial and commercial applications.
The controller accommodates common industrial motors like three-phase squirrel cage motors operating at 200 to 460 Volts AC and 50 to 60 Hertz. Typical applications include bridge cranes, trolleys, monorails, shrink wrap machines, overhead doors, conveyors, material handling equipment, compressors, fans, pumps, lifts, and elevators. The 150-F201NBDB features an open construction and should be installed in a protective enclosure to shield it from moisture and extreme temperatures.
