Allen-Bradley 160-BA03NSF1 AC Variable Frequency Drive

Allen-Bradley 160-BA03NSF1 is a compact 3-phase AC drive from the 160 SSC Smart Speed Controller family that provides analog-speed control for AC induction motors. It accepts a 380–460 VAC three‑phase input and can deliver up to 2.3 A of output current, with a nominal control input described as Analog Signal Follower in Series C. The drive is housed in an open IP20 enclosure and is convection‑cooled, weighing about 2.0 lb (0.91 kg). Mounting options include securing to a flat surface with 4.5 mm screws or using a 35 mm DIN rail, and the unit lists an operational input voltage range of 340–506 VAC with an input current around 2.8 A. The 160-BA03NSF1 is documented by suppliers as discontinued/obsolete, reflecting its status in the Rockwell Automation ecosystem. It is intended for use in industrial automation environments where a compact, analog-controlled speed solution for 3‑phase motors is required, particularly in legacy installations that rely on the 160 SSC family of drives.
