Product Overview

3ADT320700R1501 (SDCS‑PIN‑H51) is critical power‑interface and firing‑pulse board for ABB DCS500 DC drive system. It generates isolated trigger pulses for main‑circuit thyristors and supplies stable auxiliary low‑voltage power for other control‑cards inside the drive unit. Fault of this board will cause drive loss‑of‑fire or complete control‑power failure. Surplus and refurbished tested spare board for heavy‑industry DC‑drive overhaul‑projects.

Application Notes

‑ Strict ESD protection for card replacement. ‑ Verify pulse‑wiring harness integrity before power‑up. ‑ Typical deployment: DCS500 drive firing‑pulse‑power‑interface‑board spare‑part stocking.
