Product Description
UF C912 A101 (3BHE039426R0101) is a dedicated EOI (End‑of‑Instruction) high‑speed protection interface board for ABB medium‑voltage drive systems, mounted inside the drive control sub‑rack. It performs high‑speed fault detection and protection logic processing, and sends protection trigger signals to IGCT gate‑drive units for fast power‑semiconductor blocking under fault conditions, suppressing electrical transients and preventing power unit damage. Equipped with LED diagnostic indicators and G3 conformal coating for harsh cabinet‑mount installation. This model is end‑of‑life, only available as spare‑parts for existing ACS2000 and ACS6000 asynchronous drive retrofits & maintenance.
