Schneider Electric SD328AU25S2 Stepper Motor Drive

Schneider Electric's Lexium SD328AU25S2 is a compact stepper motor drive rated for up to 2.5 A per phase, designed for 115/230 VAC operation with an integrated EMI filter. As part of the Lexium SD328 family, this bipolar, two‑phase drive is intended for use with SD3‑series motor control components, delivering reliable motion to two‑phase stepper motors in automation tasks. The AU25S2 designation identifies the model variant with 2.5 A per coil, and the W FILTER specification confirms the built‑in EMI filter. This drive is suitable for industrial applications requiring precise positioning and controlled speed, such as CNC machines, packaging lines, and robotic subsystems when paired with compatible Schneider Electric controllers. Being part of Schneider Electric's Lexium SD3 ecosystem, the SD328AU25S2 supports integration with the broader SD3 control platform for compact, scalable motion control solutions. Designed to fit in standard industrial panels and compatible with common wiring practices, it suits upgrades of legacy stepper systems where a 2.5 A per coil drive is needed.
