Allen-Bradley 20G11ND027AA0NNNNN PowerFlex 755 AC Drive

Allen-Bradley PowerFlex 755 AC Drive, model 20G11ND027AA0NNNNN, is an air‑cooled, open‑type variable‑speed drive designed for 480V three‑phase motors. In normal‑duty (ND) configuration it delivers up to 20 HP with a continuous current rating of 27 A; the same PF755 family also lists a 15 HP heavy‑duty (HD) option within the same frame size, enabling selection for different load profiles. Packaged as a frame‑3 unit, the drive accepts 480 VAC, 3‑phase input and uses AC input with DC terminals for the DC link, simplifying integration into control cabinets and machines. This PowerFlex 755 unit is built for industrial automation where precise speed and torque control are required, and its open‑type design supports panel mounting in a range of environments. Typical uses include conveyors, pumps, fans, and processing equipment, where reliable variable‑speed operation helps optimize energy use and process performance. The device is part of Allen‑Bradley’s PF755 family, which is known for compact footprint and straightforward configuration and compatibility with standard PF755 accessories for networked control and I/O expansion.
