The Allen-Bradley PowerFlex® 4M (22F-A2P5N103) is a compact, micro-sized AC drive (variable frequency drive or VFD) designed for simple speed control of 3-phase motors. It is part of Rockwell Automation’s renowned PowerFlex family, known for reliability and ease of use.
This specific model is engineered for small horsepower applications and is particularly suited for use in single-phase power environments, making it a common choice for small machines, workshops, and commercial equipment in North America.
Decoding the Model Number: 22F-A2P5N103
Breaking down the catalog number provides all the key specifications:
-
22F: Series – PowerFlex 4M AC Drive.
-
A: Enclosure – IP20 (Open Type). This means it is designed to be mounted inside a control panel or a larger enclosure to protect it from dust and accidental contact. It is not dust-proof or water-resistant on its own.
-
2: Voltage Class – 200-240V AC.
-
P: Input Power Type – 1-Phase Input. This is a critical detail—it runs on standard residential/light commercial single-phase power.
-
5: Output Current – 2.3 Amps. This determines the motor size it can handle.
-
N103: Product Revision & Software – Specific firmware/hardware version (N103).

Typical Applications
This drive is ideal for applications requiring basic speed control for small 3-phase motors where only single-phase power is available. Common uses include:
-
Small Conveyors
-
Fans and Blowers
-
Pumps
-
Machine Tools (e.g., lathes, mills, drill presses)
-
Packaging Machinery
Why Choose This Drive?
-
Single-Phase Solution: Allows you to run a more efficient and controllable 3-phase motor from a common 240V single-phase outlet.
-
Motor Protection: Built-in features protect your motor from overloads, short circuits, and voltage irregularities, extending its lifespan.
-
Energy Savings: By controlling motor speed to match the load requirement (especially in fan/pump applications), it can significantly reduce energy consumption.
-
Soft Start: Gradually ramps the motor up to speed, eliminating high inrush current and reducing mechanical stress on the motor and driven equipment.
-
Rockwell Automation Reliability: As part of the Allen-Bradley family, it is built to industrial standards for durability and performance, backed by global support.
Important Considerations Before Purchase
-
Motor Compatibility: You must connect it to a 3-phase, 240V AC motor that is 0.5 HP or smaller. It will not work with a single-phase motor.
-
Enclosure: Since it’s an IP20 (open-type) drive, you must install it in a suitable electrical enclosure to ensure safety and protect it from the environment.
-
Programming: While simple, some parameters will need to be set for your specific application (e.g., motor nameplate data, acceleration time). This is done via the integral keypad.
