The strongest available identification is the ABB product information reproduced in the product record: HIEE300927R0101, OVVP, UB C717 AE01, and OVER VOLTAGE MEASURING.
I would not publish unsupported voltage thresholds, accuracy figures, or converter power ratings for this part. The available sources do not provide a sufficiently reliable ABB specification sheet for those parameters.
Application Scenarios & Pain Points
An overvoltage measurement circuit can be blamed after a converter trip simply because the diagnostic points toward the protection chain. That is dangerous reasoning. The measurement unit may be reporting a genuine DC-link or switching event rather than causing it.
- ABB power-electronics systems: UBC717AE01 is identified as an overvoltage measuring unit within ABB power-electronics hardware.
- Converter protection diagnostics: Useful for monitoring abnormal voltage conditions and feeding measurement information into the converter’s protection architecture.
- Legacy ABB drive maintenance: Relevant when the installed equipment specifically identifies the board as HIEE300927R0101 / UBC717AE01.
- Replacement of obsolete hardware: ABB lists 3BHE021887R0101 as a replacement product ID, making the replacement number important during modernization planning.
Field note: If an overvoltage measurement board fails repeatedly, check the DC-link circuit, braking arrangement, semiconductor switching devices, sensing wiring, and grounding before installing another board. Otherwise, the replacement may become another casualty.
Brief Field Case
A converter reports repeated overvoltage trips immediately after a power-stage repair. The first assumption is often a defective measurement board. A better sequence is to verify the actual DC-link behavior with appropriate instrumentation, then compare that measurement against the protection circuit’s reported value. A mismatch points toward the sensing chain; a genuine voltage spike points elsewhere.

The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — Do not confuse UBC717AE01 with a communication module.
Several secondary listings describe HIEE300927R0101 as a communication module, while the more specific product record identifies it as OVVP / OVERVOLTAGE MEASURING.
How to avoid it: Use the ABB type designation and actual PCB marking as the identification authority. Do not classify the board from a reseller category alone.
WARNING 2 — Do not replace it simply because an overvoltage alarm appears.
The board may be correctly detecting a real electrical event.
How to avoid it: Verify the actual DC-link or monitored voltage with approved test equipment. Then compare the measured value with the converter’s diagnostic value before condemning the measurement board.
WARNING 3 — Verify the replacement number carefully.
ABB’s product record associates 3BHE021887R0101 with as a replacement Product ID.
How to avoid it: Do not assume every unit carrying “UBC717” is interchangeable. Compare the complete part number, hardware revision, connector arrangement, converter model, and installed board position.
Frequently Asked Questions (FAQ)
What is ABB UBC717AE01 ?
It is an ABB overvoltage measuring unit, identified by Product ID and Type Designation OVVP, UB C717 AE01.
The unit belongs to the measurement/protection side of ABB power-electronics equipment rather than conventional PLC I/O.
What does do?
Its documented role is overvoltage measurement. In practical terms, it forms part of the voltage-monitoring/protection chain used to detect abnormal electrical conditions in the associated power-conversion equipment.
The exact measured circuit and trip threshold depend on the converter in which the board is installed.
Is the same as ?
Yes. The product record identifies as the Product ID and OVVP, UB C717 AE01 as the ABB Type Designation.
For purchasing, retain both identifiers because one may appear on the PCB while the other appears in the equipment spare-parts documentation.
What is the replacement for ?
The available product record lists 3BHE021887R0101 as the Replacement Product ID (NEW).
Before ordering the newer identification, confirm that ABB’s replacement applies to your exact converter configuration and hardware revision. A replacement number should be validated against the equipment documentation, not treated as interchangeable solely because it is listed as “new.”
Can be tested outside the original converter?
Basic electrical inspection can be performed independently, but a meaningful functional test normally requires appropriate test equipment or the associated ABB power-electronics environment.
For a refurbished unit, I would request:
- Actual-board photographs
- identification
- Hardware revision
- Connector inspection
- Insulation/isolation checks
- Measurement-channel verification
- Controlled voltage-sensing test
- Functional test report
- Warranty documentation
A simple continuity test is not enough to establish that the overvoltage measurement function is accurate.
Is a high-power converter module?
I would not classify it that way based on the available documentation. The reliable product identification describes it as an overvoltage measuring unit, despite conflicting secondary listings that characterize it as a high-power module or communication card.
That distinction matters when troubleshooting. If the board is identified as an OVVP measurement unit on the original ABB documentation, use that function as the diagnostic starting point.
What should I verify before purchasing a replacement ?
For a shutdown-critical spare, verify these items first:
- Original board revision
- Converter model and cabinet position
- Connector arrangement
- Whether the installed documentation specifies 3BHE021887R0101 as the replacement
- Actual-board photographs
- Functional test evidence
- Condition and storage history
- Warranty terms
