ABB’s product record provides the strongest identification: 3BHE003604R0102, type designation UF C765 AE102:EAF, and catalog description “EAF-BOARD COATED.”
A few secondary listings incorrectly classify this part as a generic PLC controller or fault-locating indicator. Those descriptions conflict with the ABB product record and the AC 800PEC hardware information. For procurement purposes, I would treat EAF-BOARD COATED as the authoritative product description.
Application Scenarios & Pain Points
Power-electronics control boards are not the place to guess. A board can look physically identical while carrying a different application configuration, and the resulting fault may only appear once the converter is energized.
- AC 800PEC power-electronics systems: The UFC765AE102 belongs to the hardware environment used for fast power-electronics control and process interfacing. AC 800PEC architecture includes optical controller/process-I/O connections and fast peripheral I/O.
- EAF-configured equipment: The ABB designation specifically identifies this version as an EAF board coated, distinguishing it from generic UFC765 variants.
- Legacy converter maintenance: A tested spare can reduce repair exposure when an installed power converter depends on an older AC 800PEC control architecture.
- High-power industrial drives and converters: The board belongs to the control side of power-electronics equipment, where timing, feedback, and peripheral I/O can be tightly coupled to the converter’s application software.
Field note: Before replacing the board, inspect the surrounding cabinet for heat stress and contamination. On high-power equipment, a failed control board can be the consequence rather than the original cause.

Related Products
- UFC765AE102 / 3BHE003604R0102 — Subject EAF-BOARD COATED. This exact designation should be retained for a direct replacement.
- UFC718AE01 / HIEE300936R0101 — Related ABB UFC-family power-electronics interface hardware. Its function and application differ, so it is not a direct substitute.
- AC 800PEC Controller Hardware — The broader ABB control platform associated with UFC-series power-electronics boards. The controller architecture provides fast control and peripheral interfacing.
- ABB S800 I/O — AC 800PEC documentation identifies compatibility with standard ABB S800 I/O devices; these handle field/process I/O rather than replacing the UFC765 board.
- ABB IGCT Power Devices — High-power semiconductor components used in relevant converter architectures. They form part of the power stage and are not substitutes for UFC765AE102.
- ABB Gate-Control Hardware — Associated power-semiconductor control hardware can work alongside AC 800PEC electronics, but exact interface compatibility must be verified from the converter design.
- ABB Power Electronics Interface Boards — Related UFC-family boards may provide measurement, firing, communication, or converter interface functions. Full type-code matching is required.
- ABB Converter Control Boards — Complementary control hardware within larger converter assemblies; their physical similarity should not be treated as evidence of interchangeability.
The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — Do not confuse UFC765AE102 with a generic UFC765 board.
The complete ABB designation is UF C765 AE102:EAF, with the catalog description explicitly stating EAF-BOARD COATED.
How to avoid it: Match the full 3BHE003604R0102 number and EAF designation. Record the PCB revision before removing the original.
WARNING 2 — Do not rely on generic marketplace descriptions.
Some available records describe the same part as a PLC controller or fault-locating indicator, while ABB’s product record identifies it as an EAF coated board.
How to avoid it: Use the ABB Product ID, Type Designation, physical board markings, and installed converter documentation as the primary identification chain.
WARNING 3 — ESD and contamination matter.
A coated PCB is still sensitive to electrostatic discharge and contamination around connectors. The coating is not permission to handle the board casually.
How to avoid it: Use an ESD-controlled work area, keep the board in its protective packaging until installation, inspect connector pins under magnification, and avoid touching exposed contacts.
Frequently Asked Questions (FAQ)
What is ABB UFC765AE102 3BHE003604R0102?
It is an ABB EAF coated power-electronics control board, identified by ABB Product ID 3BHE003604R0102 and Type Designation UF C765 AE102:EAF. ABB’s product record specifically describes it as “EAF-BOARD COATED.”
It is associated with ABB power-electronics control hardware rather than conventional PLC field I/O.
Is an AC 800PEC module?
The available technical documentation associates the hardware with the AC 800PEC power-electronics control environment. AC 800PEC is designed around fast control, optical controller/process-I/O connections, and dedicated peripheral I/O.
For an installed system, verify the exact converter model and board position before assuming cross-system compatibility.
What does “EAF-BOARD COATED” mean?
It is ABB’s catalog description for this particular configuration:
UF C765 AE102:EAF — EAF-BOARD COATED.
The coating is a conformal protective treatment intended to provide additional environmental protection to the PCB. It does not mean the board can be exposed to condensation or conductive contamination without risk.
Is a fault-locating indicator?
Some secondary records classify it that way, even linking the part to a fault-locating-indicator NSN. However, ABB’s own product record identifies 3BHE003604R0102 as UF C765 AE102:EAF / EAF-BOARD COATED, which is the stronger product identification.
For an engineering or procurement specification, I would use ABB’s designation rather than the conflicting generic database description.
Can I replace with another UFC-series board?
Not without checking the complete converter architecture.
At minimum, compare:
- Complete ABB Product ID
- Type designation
- PCB revision
- Converter model
- Rack/slot position
- Connector arrangement
- Firmware/application configuration
- Peripheral I/O architecture
- Control-system documentation
The configuration is part of the identification and should not be discarded during procurement.
How should a refurbished be tested?
For a critical converter spare, I would request:
- Exact identification.
- Actual-board photographs.
- PCB and coating inspection.
- Hardware revision identification.
- Connector inspection.
- Controlled power-up.
- AC 800PEC system recognition where test equipment permits.
- Peripheral/interface testing.
- Extended operating test.
- Written test results.
A board that merely powers up has not necessarily been proven functional.
What should I verify before purchasing this ABB board?
Ask for the actual board photograph, complete product number, hardware revision, condition, test status, and warranty.
For a shutdown-critical application, also provide the equipment model and existing board revision to the supplier before purchase. With older ABB power-electronics hardware, that extra comparison is often more valuable than simply finding the same front-panel label.
