Berger Lahr SD326DU25S2 Stepper Motor Drive AC

Berger Lahr SD326DU25S2 is a Schneider Electric–brand AC stepper motor drive designed to power single‑phase 230V motors, converting mains power into precise motor control signals for automation tasks. The unit accepts 115/230 VAC through an integrated mains section, reducing the need for external power components in many setups. In the SD326 family, motor voltage is specified as 230 VAC with a DC bus around 325 V, and there is no commissioning software required—the stepping resolution is selected via DIP switches. This DU25S2 variant is part of the SD326 line and is positioned as a modern option within Schneider Electric’s motion control ecosystem, including use as a replacement for older Berger Lahr WDM3 controllers. Rev 1.013 marks the hardware revision of this release.
