3. Key Technical Specifications
- Full Part Number: G2 4689070 -PS‑86
- Module Type: Power supply module (often labeled as “power module” / power module in marketplace listings)
- Function: AC‑to‑DC or DC‑DC power supply module used inside Gutor UPS or power cabinets, delivering a regulated DC output to downstream loads
- Mounting Style: Modular hot‑swappable power module designed for insertion into Gutor‑type frames or cabinets
- Electrical Role: Power‑conversion stage providing DC bus power; not a control or CPU board
- Supply Context: Typically listed and sold as a Gutor‑specific power module, not as a generic third‑party supply
- Condition in Market: Usually sold as new original or used‑surplus; price reflects sparing‑level scarcity rather than cutting‑edge specs
- Compatibility Note: Must be matched to the correct Gutor rack / cabinet type and voltage configuration before installation
4. Product Introduction
GUTOR G2 4689070 -PS‑86 is a dedicated power supply module used in Gutor UPS and industrial‑power systems. It plugs into a Gutor rack or cabinet and provides the regulated DC bus that feeds downstream converters, inverters, or control boards, so it is typically ordered as a replacement when the existing -PS‑86 module fails, trips, or shows thermal stress.
Field engineers swap this module when they see repeated over‑current or over‑temperature faults localized to one slot, or when the DC bus voltage collapses when a specific module is under load. Since -PS‑86 is not a current‑production OEM item, matching the exact G2 4689070 -PS‑86 designation and verifying input/output voltage and slot layout is more important than generic “compatible” claims.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Module slot trips upstream breaker or fuse | Internal short or overstress in -PS‑86 | ✅ High | Power‑off; check continuity from module output to DC bus and inspect for shorts | If the module is shorted, replace G2 4689070 -PS‑86 |
| DC bus voltage drops only when this module is under load | Failed or derated -PS‑86 | ✅ High | Measure DC output voltage and current at the module while under load | If the module cannot hold rated voltage at load, replace it |
| Module overheats or trips on thermal fault | Cooling failure or component aging | ✅ High | Check ambient temperature, fan operation, and heatsink cleanliness; scan with IR camera | If the module repeatedly thermal‑trips, replace it |
| Other modules work fine; only this slot faults | G2 4689070 -PS‑86 is likely the culprit | ✅ High | Swap the -PS‑86 module to another identical slot or use a known‑good one | If the fault moves with the module, keep the replacement |
| No fault on -PS‑86 but system faults upstream | Problem lies in input breaker, transformer, or bypass | ❌ Low | Inspect input‑side breakers, fuses, and bypass path first | Do not replace -PS‑86 until those are ruled out |
If the module is visibly burnt, smells of overheating, or repeatedly trips after a reset, replacement is the only safe option. Contact technical support with photos of the module label and rack configuration if the fault is unclear.

6. Frequently Asked Questions
Q: What does GUTOR G2 4689070 -PS‑86 do?
A: It is a power supply module used inside Gutor UPS or industrial‑power cabinets. It converts AC or DC input into a regulated DC bus that feeds downstream modules; it is not a control board.
Q: Is G2 4689070 -PS‑86 still in production?
A: No. It is treated as a spare‑part or obsolete module in the market, so it is only available from surplus or used‑stock vendors, not from active OEM‑line production.
Q: Can I hot‑swap G2 4689070 -PS‑86?
A: Only if the rack is designed for live‑swap and the module is rated for it. Otherwise, turn off the relevant section, lock out the DC bus, and verify there is no residual voltage before inserting or removing the module.
Q: Is this module new or refurbished?
A: In current listings, G2 4689070 -PS‑86 is typically sold as new original or open‑box surplus. If your listing claims it is refurbished, that must be explicitly stated and backed by a clear test‑report or burn‑in record.
Q: What should I check before ordering G2 4689070 -PS‑86?
A: Take a photo of the existing module label, confirm the G2 4689070 -PS‑86 part number, rack type, and input/output voltage, and verify whether the rack supports live‑swap. On Gutor systems, using a different‑sized or non‑matched power module can cause bus instability or tripping.
Q: Can I use a different -PS‑xx module instead of -PS‑86?
A: Not without confirming compatibility. Even within Gutor racks, -PS‑86 has a specific power rating and form‑fit; changing to another -PS‑xx without matching specs can overload the bus or rack.
Q: Will my UPS settings survive swapping G2 4689070 -PS‑86?
A: Yes. The module is a pure power‑path component; configuration lives in the control and network‑monitoring modules. Just document the rack position and wiring before removal.
