Product Introduction
The ABB 3BHE032285R0102 XV C772 A102 is a High Voltage Divider (HVD) board designed for the ABB ACS2000 medium-voltage variable frequency drive platform. It scales high-voltage signals into low-level feedback signals used by the drive controller for voltage regulation, protection, synchronization, and system diagnostics.
The board features a varnished PCB to improve resistance to humidity, dust, and industrial contaminants. Since it is directly involved in the drive’s voltage measurement circuit, any replacement should include verification of calibration, insulation integrity, and associated measurement wiring.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| High-voltage measurement alarm | HVD board failure | ✅ High | Review ACS2000 diagnostics and voltage feedback values | Verify board before replacing |
| Incorrect DC bus voltage reading | Divider circuit drift | ✅ High | Compare measured voltage with calibrated HV meter | Replace board if deviation exceeds specification |
| Drive trips on overvoltage | Measurement circuit error | ⚠️ Medium | Verify actual DC bus voltage independently | Eliminate power system issues first |
| Synchronization fault | Voltage feedback unavailable | ✅ High | Monitor controller feedback channels | Inspect HVD connectors and wiring |
| Intermittent voltage alarms | Loose connector or contamination | ⚠️ Medium | Inspect PCB connectors and conformal coating | Clean and reseat the board |
| Drive will not enable | Protection circuit active | ❌ Low | Review complete fault history | Verify other protection boards before replacement |
| Replacement board reports abnormal values | Incorrect hardware revision or calibration | ✅ High | Confirm part number and system compatibility | Install the correct ABB revision |
Technical Note: Voltage feedback faults are not always caused by the HVD board. Loose sensing leads, degraded insulation, DC bus disturbances, or upstream power-stage faults frequently produce similar alarms. Always compare the controller’s measured voltage with an independent high-voltage measurement before replacing the board.
Frequently Asked Questions (FAQ)
Q1. What is the ABB 3BHE032285R0102?
The 3BHE032285R0102 (XV C772 A102) is the High Voltage Divider (HVD) Board used in ABB ACS2000 medium-voltage drives. It converts high-voltage signals into low-level feedback for the control system.
Q2. Which ABB systems use this board?
ABB’s ACS2000 spare parts documentation identifies this board as the HVD Board installed in the IFU Filter Assembly of medium-voltage drives.
Q3. Is this a power board?
No. Although it operates in a high-voltage environment, the HVD board is primarily a measurement and feedback circuit board, not a power-switching module.
Q4. Can I replace the HVD board without recalibration?
In most cases, the replacement should be followed by verification of voltage feedback accuracy. Compare controller readings with calibrated test equipment and perform any commissioning procedures specified in the ABB service manual.
Q5. Can this board be replaced while the drive is energized?
No. The is a medium-voltage system containing hazardous stored energy. Isolate all power sources, verify complete DC bus discharge, and follow ABB lockout/tagout procedures before servicing.
Q6. What should I verify before ordering?
Confirm the following:
- Exact ABB part number (3BHE032285R0102)
- Type designation (XV C772 A102)
- Drive model ()
- Hardware revision
- Associated voltage measurement boards
- Existing diagnostic fault codes
Recording the measured DC bus voltage, controller feedback values, and fault history before replacing the HVD board will help determine whether the issue originates from the board itself or from another component in the medium-voltage drive system.
