Product Overview

3ADT320600R1501 (SDCS‑PIN‑H41) is pulse‑transformer isolation board for ABB DCS500 DC thyristor drives. It provides galvanic isolation and energy amplification for firing pulses sent to high‑power thyristor stacks, separating low‑voltage control electronics from high‑power main‑circuit potential. Indispensable hardware for reliable thyristor commutation. Surplus and refurbished tested spare pulse‑board for DCS500 drive maintenance‑projects.

Application Notes

‑ Observe ESD anti‑static rules during replacement. ‑ Check all pulse‑cable connections before drive commissioning. ‑ Typical deployment: DCS500 thyristor‑firing‑transformer‑board spare‑part stocking.
