Allen-Bradley 150-F43FHD SMC-Flex Solid State Controller 43A IP65

Case Study: Solving Motor Start Challenges with the Allen-Bradley 150-F43FHD

In a food processing plant, a 30 Hp conveyor motor repeatedly tripped circuit breakers during startup, causing production delays and equipment stress. The solution was the Allen-Bradley 150-F43FHD SMC-Flex solid state controller. With its soft start mode, the controller gradually ramps voltage to the motor, eliminating current spikes and reducing mechanical wear. The IP65 (Type 4/12) enclosure withstands washdown environments, ensuring reliable operation even in wet, dusty conditions.

Product Introduction

The Allen-Bradley 150-F43FHD is a solid state controller from the SMC-Flex series, designed for non-combination motor applications. It provides low-cost voltage solutions for industrial environments. The controller features a robust IP65 (Type 4/12) enclosure, making it suitable for harsh conditions. With a controller rating of 43 A and 30 Hp @ 460V AC, it handles medium-sized motors efficiently. The input line voltage is 200-208V AC, 3-phase, 50 and 60 Hz, and the control voltage is 100-240V AC (5-480 A units).

Technical Specifications Breakdown

Key specifications of the 150-F43FHD include:

Input Line Voltage: 200-208V AC, 3-phase, 50 and 60 Hz — ensures compatibility with standard three-phase power systems in North America and other regions.

Control Voltage: 100-240V AC (5-480 A units) — allows flexible connection to common control power sources without needing additional transformers.

Controller Rating: 43 A, 30 Hp @ 460V AC — delivers sufficient capacity for medium-duty motor applications.

Enclosure Type: IP65 (Type 4/12) — provides protection against dust ingress and water jets, ideal for washdown or outdoor installations.

Industry Applications

The 150-F43FHD excels in several industrial settings:

Food & Beverage: The IP65 enclosure withstands high-pressure washdowns, while soft start reduces mechanical shock on pumps and conveyors.

Water Treatment: Linear speed acceleration ensures gentle starts for large pumps, preventing water hammer and pipe stress.

HVAC: Dual ramp start allows customized acceleration profiles for fans and compressors, improving energy efficiency.

Installation & Setup Guidance

Mount the 150-F43FHD in a location that allows adequate airflow around the IP65 enclosure. Connect the three-phase input line voltage (200-208V AC, 50/60 Hz) to the line terminals. Provide a separate single-phase control source of 100-240V AC for the controller electronics. For fan operation, supply a separate 120V or 240V single-phase power source. Use the keypad to select one of the seven standard operating modes: soft start, selectable kickstart, current limit start, dual ramp start, full voltage start, linear speed acceleration, or preset slow speed. Optional pump control and braking control modes are also available.

Maintenance & Reliability

The 150-F43FHD includes built-in electronic motor overload protection and metering with CT on each phase, reducing the need for external devices. Periodically inspect the IP65 enclosure seals to maintain protection against moisture and dust. The LCD display and keypad allow easy monitoring and parameter adjustments without opening the enclosure. Routine checks of the control voltage and input line connections help ensure long-term reliability. For complete technical specifications, please contact BluePLC Industrial.

Compatibility & Integration

The 150-F43FHD integrates with automation systems via DPI communication, enabling optional connections to communication modules and human interfaces. It also features 4 programmable auxiliary contacts and a built-in SCR bypass or run contactor. The controller complies with UL 508, CSA C22.2 NO.14, EN/IEC 60947-1, and EN/IEC 60947-4-2, and is certified by cULus, CSA, CCC, and CE. This ensures seamless integration into existing control networks.

Buying Guide

Before purchasing the Allen-Bradley 150-F43FHD, verify that your motor's full-load current does not exceed 43 A and that your supply voltage matches 200-208V AC, 3-phase. Confirm the control voltage requirement (100-240V AC) and ensure a separate fan power supply is available. BluePLC Industrial offers this controller with fast shipping and expert support.
