Allen-Bradley 150-F85FBD SMC-Flex Solid State Controller 85A 60HP

Product Overview

When managing industrial motor loads, selecting a controller that combines rugged environmental protection with precise starting and stopping capabilities is critical. The Allen-Bradley 150-F85FBD is a solid state controller from the SMC-Flex line, designed for three-phase applications requiring up to 85 A and 60 HP at 460V AC. Its IP65 (Type 4/12) enclosure makes it suitable for washdown or dusty environments, reducing the need for additional cabinets. Whether you are retrofitting an existing line or specifying a new installation, this unit offers a compact, integrated solution.

Technical Specifications Breakdown

Key parameters for the 150-F85FBD are listed below for quick reference:

Industry Applications

This controller is well-suited for pump, fan, and conveyor systems where controlled acceleration reduces mechanical stress and current spikes. For example, in a water treatment facility, the soft start mode minimizes water hammer and extends pump life. In material handling, the dual ramp feature allows different start profiles for loaded versus empty conveyors, improving operational efficiency. The 150-F85FBD also supports wye-delta and six-lead motors, making it versatile for retrofit projects where motor configurations vary.

Installation & Setup Guidance

Mount the controller in a location that allows adequate airflow around the IP65 enclosure. Ensure the incoming three-phase supply matches the 400-460V AC range and that a separate single-phase control source (100-240V AC) is available for the logic board. When wiring, follow the torque specifications provided in the manual for the power terminals. The front keypad and backlit LCD simplify configuration of starting modes such as soft start, current limit, or linear speed acceleration. Always verify phase rotation before commissioning to avoid phase reversal faults.

Maintenance & Reliability

The enclosed design reduces dust ingress, but periodic inspection of the cooling fins and terminal connections is recommended. Ambient temperature during operation should remain between 23 and 104 °F; storage range is -4 to 167 °F. The controller includes self-diagnostics for faults like undervoltage, overvoltage, overload, and jam conditions. Monitoring the status indicators and logging any communication faults helps maintain uptime. No internal adjustments are required under normal conditions.

Selection Guide & Purchasing Advice

When evaluating the 150-F85FBD for your application, confirm that the motor full-load current does not exceed 85 A and that the supply voltage is within the 400-460V AC range. The IP65 rating eliminates the need for a separate enclosure in many environments, reducing total installed cost.
