3. Key Technical Specifications
- Part Number: 640‑0573
- Revision: Commonly REV 03 (linked with 0P0363 PCB)
- Board Type: PCB Circuit Board / Dedicated Controller
- Function: Control or I/O board within Gutor UPS racks, not a standalone enclosure
- Typical Interface: Described as having CAN bus communication and I/O capability
- Operating Voltage: Listed around 110 V DC in some spares‑market data
- Memory / Logic: Framed in surplus ads as a “dedicated controller” with data memory, not a simple relay‑board
- Mounting: Designed for insertion into a Gutor rack or control cabinet, using standard PCB‑type connectors
- Supply Status: Not in current OEM production; typically sold as new‑original or used
4. Product Introduction
Gutor 640‑0573 is a PCB‑type control or I/O board used in Gutor UPS and industrial power systems. It is often paired with 0P0363 and described as a dedicated controller, so it handles logic, data memory, and CAN‑bus communication rather than carrying the main power path.
Plant engineers usually order this board when they see intermittent faults localized to the control or I/O rack, or when the UPS log points directly to a “controller” or “I/O PCB” failure. Because it is marked as discontinued in spares channels, the correct revision (REV 03) and mechanical match matter more than generic “compatible” UPS PCBs.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| CAN bus or communication faults to this board | Failed 640‑0573, loose connector, or wrong configuration | ✅ High | Check continuity of CAN lines and measure supply voltage at the board | If the board is powered, wired correctly, and still faults, replace 640‑0573 |
| I/O points or indicators hang or disappear | Internal fault on this PCB‑level logic | ✅ High | Cross‑check with another board of the same type or by swapping slots | If the fault moves with the board, replace 640‑0573 |
| Intermittent faults that clear after re‑powering | Aging components or poor thermal behavior on the PCB | ✅ Medium | Run under load and monitor temperature with an IR camera | If faults repeat under load, replace the board |
| All other modules behave normally; only this board reports faults | 640‑0573 is likely the culprit | ✅ High | Temporarily swap in a known‑good board of the same number and revision | If the symptoms vanish, keep the replacement |
| No fault on 640‑0573 but higher‑level communication breaks | Fault lies in network gateway or SCADA interface, not here | ❌ Low | Check network‑monitoring or gateway modules first | Do not replace 640‑0573 until those are ruled out |
If the board is visibly burnt, smells of overheating, or shows cracked components, replacement is the only safe option. Contact technical support with photos of the board label, connector side, and diagnostic logs.
6. Frequently Asked Questions
Q: What does Gutor 640‑0573 do?
A: It is a PCB‑level controller or I/O board used in Gutor UPS racks, often linked to 0P0363. It handles CAN bus communication, logic signals, and some data memory, not the main power conversion.
Q: Is 640‑0573 still in production?
A: No. It is treated as a discontinued part in the spare‑parts market, so it is only available from surplus or used‑stock channels.
Q: Can I substitute a different 640‑xxxx board for 640‑0573?
A: Not safely. Each 640‑number matches a specific function and wiring scheme. Use only the exact 640‑0573 REV 03 board unless the OEM explicitly lists a cross‑reference.
Q: Is this board new or refurbished?
A: In the market, 640‑0573 is typically sold as new original or open‑box surplus. If your listing uses “refurbished,” that must be explicitly stated and backed by a clear test report.
Q: Can I hot‑swap 640‑0573?
A: No. Power down the rack, lock out the DC bus, and verify there is no residual voltage before inserting or removing this controller / I/O board. Live swapping can corrupt configuration or damage the bus.
Q: Will my UPS configuration survive replacing 640‑0573?
A: Yes, because configuration is stored in other modules, not in this PCB. Just document settings and wiring before removal, and restore them afterward.
Q: What should I check before ordering 640‑0573?
A: Take a clear photo of the existing board label, note the 640‑0573 REV 03 designation, and confirm the slot position and wiring diagram. On legacy Gutor systems, using a similar‑sounding board or a wrong revision can cause hidden faults that only show up under load.
