Compatible Replacement & Equivalent Models
When the original UNS0868B-P V2 is unavailable or cost-prohibitive, the following alternatives warrant engineering evaluation:
- UNS0868B-P V1 (3BHE013940R0001) — First-generation revision; functionally equivalent in most installations. Confirm connector pinout and firmware compatibility before substitution.
- UNS0868A-P — Earlier platform variant; may require bracket or connector adapter. Consult ABB system documentation.
- 3BHE013940R0003 (V3, if released) — Later revision with potential firmware enhancements; backward-compatible in most UNITROL 6000/6800 cabinets.
- OEM-equivalent rebuilt boards — Konmask sources remanufactured units tested to original ABB test specifications. Suitable for non-critical auxiliary systems or as cost-reduction alternatives.
⚠ Engineering Note: Always verify the hardware revision accepted by your system’s firmware before installing a replacement. Contact Konmask technical support for a compatibility check.
Why Choose the Original Model
- Guaranteed firmware compatibility — V2 revision aligns with UNITROL 6000/6800 firmware versions released post-2010.
- Improved thermal design — V2 incorporates enhanced heat dissipation over V1, extending MTBF in high-ambient environments.
- Direct plug-and-play replacement — No re-parameterization required when replacing a failed V2 unit with a new V2.
- Full ABB traceability — OEM units supplied by Konmask include original ABB labeling and serialization for asset management compliance.
- Warranty coverage — New OEM units carry standard ABB warranty; Konmask-refurbished units carry a 12-month functional warranty.
Typical Applications
- ABB UNITROL 6000 / 6800 automatic voltage regulators (AVR) for synchronous generators
- ABB MEGADRIVE-LCI load-commutated inverter drive systems
- AC800PEC-based high-power drive control cabinets
- Power plant auxiliary excitation panels (hydro, thermal, wind)
- Industrial motor drive retrofit and upgrade projects
- Marine propulsion drive control systems
System Compatibility
| ABB Platform | Compatible | Notes |
|---|---|---|
| UNITROL 6000 | ✅ Yes | Primary target platform |
| UNITROL 6800 | ✅ Yes | Verify cabinet slot assignment |
| UNITROL 5000 | ⚠ Conditional | Requires adapter; consult Konmask |
| MEGADRIVE-LCI | ✅ Yes | Power supply sub-rack application |
| AC800PEC | ⚠ Conditional | Confirm I/O rail voltage requirements |
| UNITROL 1000 / 1020 | ❌ No | Different power architecture |
Selection Guide
Use the following decision matrix to select the correct power supply module:
- Step 1 — Identify your platform: Confirm the ABB system model from the cabinet nameplate or engineering drawing.
- Step 2 — Check the part number: Locate the existing board’s label. If it reads 3BHE013940R0002, you need an exact V2 replacement.
- Step 3 — Assess revision tolerance: If your system firmware supports V1 or V3, a cross-revision replacement may reduce lead time and cost.
-
Step 4 — Choose condition grade:
- New OEM — Critical generation assets, long-term installations
- Tested Refurbished — Budget-sensitive projects, secondary systems
- Exchange — Fastest turnaround; send your failed unit, receive a tested replacement
- Step 5 — Contact Konmask: Provide your system serial number for final compatibility confirmation before ordering.

Replacement & Compatibility FAQ
Q: Can I use a V1 (3BHE013940R0001) board in place of a V2?
A: In most UNITROL 6000 installations, yes — the hardware interface is identical. However, confirm with your system’s firmware release notes, as some V2-specific features may not be available on V1 hardware.
Q: Is a refurbished unit safe for a critical power generation application?
A: Konmask refurbished units undergo full functional testing under load conditions. For tier-1 generation assets, we recommend new OEM units. For secondary or backup systems, tested refurbished units offer excellent value.
Q: How do I identify a counterfeit UNS0868B-P?
A: Genuine ABB boards feature laser-etched part numbers, ABB holographic labels, and consistent PCB trace quality. Konmask supplies only traceable, verified units — contact us if you have authenticity concerns about a board already in your possession.
Q: What is the typical failure mode for this power supply?
A: Common failures include electrolytic capacitor degradation (especially in high-temperature environments), MOSFET gate-drive faults, and output rail voltage drift. Konmask can perform a fault diagnosis on your returned unit.
Q: Do you offer an exchange / core return program?
A: Yes. Ship your failed unit to Konmask and receive a tested replacement at a reduced exchange price. Contact us to initiate an RMA.
