Product Overview

CE4003S2B6 is core digital control board for Cegelec / Alstom legacy DC drive cabinets. It implements high‑speed current‑loop and speed‑loop closed‑loop control for large DC motors applied in steel‑mill rolling‑mill, paper‑machine and heavy‑industry main‑drive systems. Processes encoder speed‑feedback signal and generates thyristor‑firing pulse commands for power‑stage. Obsolete legacy‑drive spare hardware, refurbished and surplus tested assemblies for heavy‑industry drive‑cabinet overhaul and maintenance‑projects.

Application Notes

‑ Strict ESD anti‑static handling during board replacement. ‑ Match firmware version with existing drive‑system configuration. ‑ Perform full‑function drive test after board swap‑out. ‑ Typical deployment: heavy‑industry DC‑drive control‑board spare‑part stocking.
