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

Product Overview

When motor reliability and serviceability matter most, the Allen-Bradley 150-F85FBD SMC-Flex solid state controller delivers. Designed for maintenance engineers who value uptime, this enclosed non-combination smart motor controller handles 85 A and 60 HP at 460V AC. Its IP65 (Type 4/12) enclosure protects against dust and water jets, making it suitable for harsh environments.

Technical Specifications

The 150-F85FBD operates on an input line voltage of 400-460V AC, 3-phase, at 50 and 60 Hz. Control voltage is 100-240V AC (for 5-480 A units). Rated voltage is 400/415/460V AC. The controller supports motor currents from 17 to 85 A, with a kW rating of 45 kW at 50 Hz and an HP rating of 60 HP at 60 Hz. Ambient temperature range during storage is -4 to 167 °F, and 23 to 104 °F during operation.

Key Features for Maintenance Engineers

This controller includes selectable starting and stopping modes: dual ramp, current limit start, soft start, linear speed acceleration, preset slow speed, full voltage start, and soft stop. A backlit LCD and front keypad simplify local monitoring and adjustments. Four fully programmable auxiliary contacts reduce the need for external relays. Fault detection covers excessive starts, line faults, undervoltage, open gate, phase reversal, stall, overvoltage, overload, communication fault, underload, power loss, jam, controller temp, and voltage unbalance—helping you diagnose issues quickly.

Industry Applications

The 150-F85FBD is ideal for controlling wye-delta, six-lead motors, and standard squirrel-cage induction motors. Common applications include conveyors, pumps, fans, and compressors in manufacturing, water treatment, and HVAC systems. Its robust enclosure and wide voltage range make it a versatile choice for facilities requiring reliable motor starting and stopping.

Installation & Setup Guidance

Mount the controller in a clean, dry location within the specified ambient temperature range. Ensure the input line voltage matches 400-460V AC, 3-phase, 50/60 Hz. Connect a single-phase control source of 100-240V AC at 50/60 Hz. Use appropriately rated wiring and follow local electrical codes. The front keypad and LCD allow straightforward configuration of starting modes and parameters.

Maintenance & Reliability

Routine inspection of the enclosure seals and cooling vents helps maintain IP65 protection. Periodically verify that the ambient temperature stays within 23 to 104 °F during operation. Check for fault codes on the LCD and address any alarms promptly. The controller's solid-state design reduces wear compared to electromechanical starters, lowering long-term maintenance costs.

Selection Guide & Purchasing Advice

Before purchasing, confirm that the 150-F85FBD matches your motor's full-load current (17-85 A) and voltage requirements (400-460V AC). Verify the enclosure type suits your environment.
