ABB DSAB‑01C 64630199Q Diode Trigger Board

ABB DSAB‑01C 64630199Q is a rectifier trigger auxiliary board for ABB ACS800 series AC drives. It processes trigger pulses for the rectifier power section, monitors current‑voltage status of power unit, and implements over‑current and over‑voltage protection logic for drive rectifier bridge. It is a key internal power‑circuit component inside ACS800 inverter cabinet.

This PCB board integrates power capacitors, fuses and signal conditioning circuits. It connects with main control board via internal headers, and supports revision upgrade for different hardware versions. It is widely used as replacement spare‑part for on‑site troubleshooting, drive‑equipment maintenance and legacy ACS800‑system retrofit projects.
