Allen-Bradley 22C-D030N103 PowerFlex 400 AC Drive

The Allen-Bradley 22C-D030N103 PowerFlex 400 is a 20 HP (15 kW) variable-frequency drive designed to regulate the speed and torque of three-phase AC motors in industrial control systems. It accepts 480 V AC input, provides up to 30 A on the output, and uses a V/Hz control scheme with a speed range of 0–400 Hz for pumps, fans, conveyors, compressors, and HVAC applications where precise motor regulation and energy efficiency are needed. The drive is a panel-mount unit with an IP20 enclosure and an open NEMA Type design, manufactured by Allen-Bradley (Rockwell Automation). Common replacements include Allen-Bradley 25B-D030N114, Allen-Bradley 20AD033A3AYNANC0, and Siemens 6SL3224-0BE27-5UA0.
