Product Details

The DSAB‑01C is a robust Diode Rectifier Board for ABB industrial drive and excitation power equipment, it is key Power‑unit Protection Board inside power conversion cabinet. It undertakes AC‑DC rectifying work, converts alternating current from main circuit into direct current for subsequent power unit operation.

Equipped with industrial high‑power diodes, fuses and filter capacitors, the board realizes bridge‑type rectification. The integrated fuse components offer fast over‑current protection to prevent damage caused by short‑circuit fault. Filter circuit suppresses power‑supply ripple and improves DC output quality. Multi‑pin plug‑in connectors simplify installation and replacement procedures.

Built‑in hardware monitoring detects fuse blown and internal component abnormal status. Fault signals can be transmitted to upper control board through signal terminals. Industrial‑grade circuit design adapts to high‑interference power cabinet environment.

Adopting standard rack‑slot installation inside drive cabinet. Widely applied in generator excitation, large‑variable‑speed drive and other industrial sites. It is essential power hardware for power unit overhaul, rectification circuit maintenance and defective diode board replacement.
