Product Overview

ACHM‑01C (68449022) is ABB ACS800‑104 multi‑drive pre‑charge control PCB board. It manages DC‑bus soft‑charging relay sequence to suppress inrush current during drive power‑up, protecting main power semiconductors. It is an internal critical spare component for regenerative multi‑drive racks used in metallurgy, paper‑making and large production‑line machinery. Obsolete series spare hardware; surplus and refurbished tested board for drive‑cabinet maintenance and overhaul projects.

Application Notes

‑ Strict ESD protection must be applied during PCB replacement. ‑ Verify relay contact integrity before power‑on after board swap. ‑ Execute complete drive power‑on sequence test after installation. ‑ Typical deployment: ABB ACS800‑104 charging‑control‑board spare‑part stocking.
