Allen-Bradley 150-F135NBD SMC Flex Smart Motor Controller

Product Overview

The Allen-Bradley 150-F135NBD is a solid-state controller from the SMC-Flex product line. It functions as a soft starter to protect motors during startup, but also offers multiple control modes for stopping and idle operation. This unit provides maximum continuous output current of 135.0 A and output power of 100 HP at 460VAC rated voltage, with an open type enclosure.

Technical Specifications Breakdown

Key parameters for the 150-F135NBD are listed below for quick reference:

Industry Applications

This controller suits applications requiring controlled motor acceleration and deceleration, such as conveyors, pumps, fans, and compressors. The 150-F135NBD supports multiple operating modes including Soft Start, Full Voltage Start, Smart Motor Braking, Current Limit Start, Dual Ramp Start, Accu-Stop, Selectable Kickstart, Pump Start, Slow Speed with Braking, Coast-to-rest, Preset Slow Speed, Linear Speed Acceleration (Tachometer required), Soft Stop, and Pump Stop. This versatility reduces mechanical wear and improves process control.

Installation & Setup Guidance

Mount the controller in a clean, dry environment with adequate ventilation. Ensure the line voltage matches the 200…460V AC, 3-phase, 50/60 Hz specification. Connect control wiring for 100…240V AC (for 5…480 A units). The controller provides four fully programmable auxiliary contacts for normal/up-to-speed/fault/alarm/network (N.O./N.C.) or external bypass (N.O. only). Use the DPI ports for optional human interface or communication modules.

Maintenance & Reliability

Periodically inspect the controller for dust accumulation, loose connections, and signs of overheating. The unit includes comprehensive protection and diagnostics: power loss, line fault, voltage unbalance, excessive starts/hour, phase reversal, undervoltage, overvoltage, controller temp, stall, jam, open gate, overload, underload, and communication fault. Metering functions track amps, volts, kW, kWh, MW, MWH, elapsed time, power factor, and motor thermal capacity usage.

Compatibility & Integration

The 150-F135NBD integrates via one DPI port for optional human interface and another DPI port for communication. It can be used as a line controller or delta controller, with output characteristics varying by mode. The alarm contact signals overload, underload, undervoltage, overvoltage, unbalance, jam, stall, and ground fault conditions externally.

Selection Guide & Purchasing Advice

When selecting a motor controller, verify that the voltage, current, and power ratings match your motor and system requirements. The 150-F135NBD is rated 135 A, 100 Horsepower at 460 Volts AC.
