Product Introduction
ABB 3BHB002751R0106 is an ACS1000 rectifier supervision board used in medium-voltage drive systems. It monitors the rectifier section and supports safe operation of the drive.
This board is normally sourced for repair or maintenance on installed ACS1000 equipment, so exact label matching matters. Verify the alternate designation, revision, and drive compatibility before ordering.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to This Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Rectifier supervision alarm appears | Failed supervision board or rectifier fault | ✅ High | Read the drive alarm log and inspect the board status | Confirm the rectifier before replacing the board |
| Drive will not enable | Supervision interlock active or missing board feedback | ✅ High | Check interlock status and input signals at the drive controller | Verify board feedback and wiring first |
| Alarm appears only at startup | Loose connector or failed board initialization | ✅ High | Reseat the board and compare startup diagnostics | If the alarm repeats, replacement is likely |
| Overvoltage or rectifier fault codes repeat | Actual rectifier issue or bad sensing path | ✅ High | Measure rectifier inputs and compare to drive diagnostics | Check the rectifier stage before blaming the board |
| No response from the supervision circuit | No control power, cable issue, or internal fault | ✅ High | Measure the supply and inspect cable continuity | Verify power and wiring first |
| Other drive boards also report faults | Common power/backplane issue | ❌ Low | Check the drive’s auxiliary supply and backplane health | Fix the system-level issue first |
If you are stuck, send photos of the board, drive cabinet, and alarm log to technical support.

Frequently Asked Questions
Q: What is the ABB 3BHB002751R0106 used for?
A: It is an ACS1000 rectifier supervision board used in ABB medium-voltage drive systems.
Q: Is this part obsolete?
A: It is a legacy ACS1000 item, so stock is usually limited and often sold as surplus or refurbished.
Q: Is XVC722AE01 the same part?
A: The listings indicate XVC722AE01 as the alternate designation, but I would still verify the exact label on the shipped board before installation.
Q: Can I replace it with a similar ABB drive board?
A: Not safely by family name alone. The drive type, revision, and supervision function need to match the installed system.
Q: Is it hot-swappable?
A: No. Power down the drive cabinet before removal. Live removal can damage the board or trigger a drive fault.
Q: Why is the price lower than factory new?
A: Because these parts are often surplus, recovered from closed projects, or sold as tested used stock. Lower price is fine if the condition and test history are clear.
Q: What should I verify before ordering?
A: Confirm the full part number, alternate designation, ACS1000 compatibility, and board revision. That avoids the common mistake of buying a board that looks right but does not fit the drive.
