Allen-Bradley 150-F480NCR SMC-Flex Solid State Controller 480A

Product Overview

When a large motor in a critical process fails to start smoothly, the resulting mechanical shock and voltage dips can damage equipment and halt production. The Allen-Bradley 150-F480NCR SMC-Flex Solid State Controller directly addresses this challenge. Part of the proven SMC-Flex family, this open-enclosure controller delivers controlled starting and stopping for demanding loads up to 480 A and 400 Hp at 460V AC. Its robust design handles input line voltages from 200-575V AC, three-phase, at both 50 and 60 Hz, making it a versatile choice for global installations.

Technical Specifications

The 150-F480NCR provides a controller rating of 480 A and 400 Hp @ 460V AC, with a rated voltage of 500/575V AC. It accepts a wide input line voltage of 200-575V AC, three-phase, 50 and 60 Hz. The control voltage is 24V AC/DC for units rated 5-480 A. This solid state controller comes in an open enclosure and weighs 32.00 lbs (14.51 kg).

Industry Applications

This controller excels in heavy industrial applications such as conveyors, pumps, compressors, and fans where controlled acceleration reduces mechanical stress. For example, in a mining conveyor system, the 150-F480NCR eliminates belt jerk and material spillage by ramping up torque smoothly. In water treatment plants, it prevents pressure surges during pump startup, extending pipeline life. Its wide voltage range also suits facilities with fluctuating line conditions.

Installation & Setup

Mount the open-enclosure controller in a clean, dry cabinet with adequate ventilation. Ensure the three-phase input line voltage (200-575V AC) matches the supply. Connect the 24V AC/DC control voltage as specified for the unit. Use properly rated conductors for 480 A continuous current. Follow all local electrical codes and the manufacturer's wiring diagram. Verify that the motor's full-load current does not exceed the controller rating.

Maintenance & Reliability

Periodically inspect the controller for dust accumulation, loose connections, and signs of overheating. Keep the enclosure interior clean and ensure cooling airflow is unobstructed. The solid-state design reduces wear compared to electromechanical starters, leading to longer service life and lower maintenance costs. For maximum reliability, schedule annual thermal imaging checks on power connections.

Selection Guide & Purchasing Advice

Before ordering, confirm that the motor horsepower and full-load current are within the 480 A and 400 Hp @ 460V AC rating. Verify the input line voltage falls within 200-575V AC, three-phase. For units above 480 A, note the control voltage specification changes. BluePLC Industrial stocks the Allen-Bradley 150-F480NCR and can assist with availability and replacement options.
