The Allen-Bradley 22B-A2P3N104 is a PowerFlex 40 series AC drive module designed for simple and reliable variable speed control of small industrial motors. Operating in the 0.4 kW (0.5 HP) class, it delivers stable V/Hz scalar control, making it ideal for conveyors, fans, pumps, and light OEM machinery where ease of use and cost efficiency are critical.
This drive is widely used in panel-mounted automation systems due to its compact footprint, straightforward keypad interface, and dependable performance in standard industrial environments. It supports both standalone operation and basic PLC integration via RS-485 communication.
Although now officially discontinued (as of June 30, 2025), it remains heavily used in maintenance and retrofit applications thanks to its large installed base and proven field reliability.
