Allen-Bradley 22C-D022N103 PowerFlex 400 AC Drive

The Allen-Bradley 22C-D022N103 PowerFlex 400 AC Drive is a 10 HP, three‑phase variable frequency drive designed for frequency drive systems that control the speed and torque of three‑phase AC motors. It accepts 240 V AC input, provides up to 22 A on the output, and uses V/Hz control over a 0–400 Hz range to support both constant torque and variable torque applications, commonly in fan systems, pump stations, HVAC equipment, cooling towers, and industrial ventilation. The enclosure is IP20 with a NEMA Type Open configuration and panel mounting. Manufactured by Allen-Bradley (Rockwell Automation), the PowerFlex 400 family is used for retrofit projects, drive replacements, panel upgrades, and process optimization to improve operational performance and energy efficiency. A common replacement for this model is the Allen-Bradley 25A-D024N104.
