Allen-Bradley 150-F201NCR SMC-Flex Solid State Controller 201A

Product Overview

The 150-F201NCR is an open-type solid-state controller from the Allen-Bradley SMC-Flex series. It delivers a controller rating of 201 A and 150 HP at 460V AC, making it suitable for medium-to-large induction motors. The unit accepts a three-phase input line voltage of 200-575V AC at 50 and 60 Hz, with a rated voltage of 500/575V AC. Control voltage is 24V AC/DC (for 5-480 A units). This controller is compatible with standard squirrel-cage induction motors and wye-delta, six-lead motors.

Technical Specifications Breakdown

Key parameters for the 150-F201NCR are listed below for quick reference:

Industry Applications

Typical uses include conveyors, pumps, fans, and compressors in manufacturing, water treatment, and HVAC systems. The ability to select from multiple start modes—such as current limit start, soft start, and dual ramp—allows operators to tailor motor starting to specific load conditions, reducing mechanical shock and extending equipment life.

Installation & Setup Guidance

Mount the open-type controller in a clean, dry enclosure rated for the environment. Ensure adequate ventilation for heat dissipation. Connect three-phase power to the input terminals per the wiring diagram provided with the unit. The control voltage (24V AC/DC) must be supplied from a separate source or transformer. Configure start and stop modes via the front-panel keypad and backlit LCD. Verify that the motor current falls within the 116 to 348 A range for this controller.

Maintenance & Reliability

Periodically inspect the controller for dust accumulation, loose connections, and signs of overheating. Ambient storage temperature should be between -20 and 75 °C; operating temperature between -5 and 50 °C. Do not exceed an altitude of 2000 m. The controller includes built-in diagnostics for faults such as overvoltage, undervoltage, overload, phase reversal, and communication faults, aiding proactive maintenance.

Compatibility & Integration

The 150-F201NCR integrates with automation systems via its DPI port, allowing communication with Allen-Bradley drives and controllers. Four fully programmable auxiliary contacts provide status feedback. The unit is compatible with standard squirrel-cage induction motors and wye-delta, six-lead motors, offering flexibility in retrofit and new installations.

Selection Guide & Purchasing Advice

When selecting a solid-state controller, match the controller rating to the motor full-load current and horsepower. For applications requiring higher or lower ratings, consult the SMC-Flex lineup.
