Product Overview
The Allen-Bradley 150-F25NBDB SMC-Flex solid-state controller delivers dependable motor starting and stopping for industrial applications. This Bulletin 150 controller handles 25 Amps and supports motors from 5 to 15 Horsepower at 460 Volts AC. Its open enclosure design suits panel-mounted installations where ambient temperatures stay between -5 and 50 degrees Celsius.
Engineers choose the 150-F25NBDB for its flexible control options, including soft start, current limit start, dual ramp, full voltage, linear speed acceleration, preset slow speed, and soft stop. The controller also provides comprehensive protection against power loss, line faults, voltage unbalance, excessive starts per hour, phase reversal, under/over-voltage, excessive temperature, stalling, jams, open gates, overloading, underloading, and communication faults. This robust feature set minimizes downtime and protects valuable equipment.

Key Features & Benefits
- Wide input voltage range (200-480 VAC) accommodates global installations.
- Integrated pump control reduces hydraulic shock and extends pump life.
- Multiple starting modes provide flexibility for different load requirements.
- Comprehensive fault protection prevents equipment damage and unplanned downtime.
- Built-in metering (Amps, Volts, kW, kWH, mW, mWH, elapsed time, power factor, motor thermal capacity) enables real-time monitoring.
- Status indicators clearly show stopping, starting, at-speed, alarm, and fault conditions.
Industry Applications
The Allen-Bradley 150-F25NBDB excels in pumping systems where its pump control option reduces pressure surges and water hammer. In conveyor applications, the soft start feature limits torque stress on belts and gearboxes. HVAC systems benefit from controlled acceleration, reducing mechanical wear and energy spikes.
For retrofit projects, the 150-F25NBDB replaces older electromechanical starters, bringing modern protection and diagnostics. Its 2-wire and 3-wire control wiring options simplify integration into existing control panels.
Installation & Setup Guidance
Mount the 150-F25NBDB in a clean, dry enclosure with adequate ventilation. Maintain clearance around the unit for heat dissipation. Connect power wiring per the nameplate ratings, ensuring the line voltage matches 200-480 VAC, 3-phase. Use the provided DPI port for HMI connectivity. Configure the controller using the integrated keypad or software, selecting the appropriate starting mode and pump control option. Verify control voltage (100-240 VAC) before energizing.
Maintenance & Reliability
Routine inspection every 6 months is recommended. Check for dust accumulation, loose connections, and signs of overheating. The controller's self-diagnostics help identify faults early. Operating within the specified temperature and humidity ranges ensures long-term reliability. The open enclosure design requires a clean environment or a proper cabinet to protect against contaminants.
Selection Guide & Purchasing Advice
Before purchasing, confirm your motor's full-load current and voltage rating. Verify that the 150-F25NBDB's 25 Amp rating matches your application. Ensure your control system provides the required control voltage. For additional support, PLC Source PRO offers genuine Allen-Bradley parts and expert guidance.
