ABB spare-part data explicitly identifies the product as KV C758 A124:IPS DUAL; VOLTAGE SUBPRINT, gives a net weight of 0.26 kg, and lists ACS5000 Water Cooled under its documented spare-part applications.
An ABB electrical parts list independently places 3BHE021951R0124 in the inverter section as the Dual voltage sub-print — KV C758 A, alongside the IGCT power supply, EAF board, phase-modulator interface, CVMI, SVA, SCA, and high-voltage divider assemblies. That context is important because it confirms this is a power-electronics subprint rather than a general-purpose PLC module.
Product Introduction
The ABB 3BHE021951R0124 is a KV C758 A124 IPS Dual Voltage Subprint used in ABB medium-voltage drive power electronics. ABB’s spare-part identification classifies it as a voltage subprint and documents its use in the ACS5000 Water Cooled drive family.
In the inverter assembly, the board belongs to the power-supply/control electronics surrounding the high-power semiconductor stage. It should therefore be treated as a drive-specific PCB, not as a standalone power supply, PLC CPU, or generic voltage-monitoring card. The exact drive electrical drawing should be used to confirm its position and connected circuitry before replacement.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
A failed IPS voltage subprint can produce symptoms that look like a larger drive-control or power-stage failure. Before replacing the board, maintenance should distinguish between a defective subprint, upstream supply problems, insulation faults, gate-unit issues, and problems elsewhere in the inverter cell.
Typical Applications
- ABB ACS5000 Water Cooled drives — the documented spare-part application for 3BHE021951R0124.
- Medium-voltage inverter power sections — installed within ABB high-power converter electronics.
- IGCT-based inverter assemblies — the associated electrical parts list places the board alongside ABB IGCT power-supply and inverter control components.
- Drive maintenance and board-level replacement — suitable when the original KV C758 A124 board must be replaced with an exact configuration match.
Technical Pitfalls to Avoid
- Do not describe it as a generic PLC power module.
The ABB catalog identifies 3BHE021951R0124 as a voltage subprint, and the associated parts list places it inside an ACS5000 inverter assembly. Generic descriptions such as Ethernet module, DCS I/O card, or general-purpose power supply are not supported by the stronger identification. - Do not assume that “dual voltage” means a universal 24 VDC/48 VDC power supply.
The phrase IPS DUAL is part of ABB’s specific type designation. Public reseller pages publish conflicting electrical values, including processor, memory, input-voltage, and output-frequency specifications that are not supported by the ABB spare-part record. Those values should not be copied into an engineering specification without the applicable ABB circuit documentation. - Match the complete drive configuration.
The board is used alongside other specialized ABB inverter boards such as the CVMI, SVA, SCA, EAF, phase-modulator interface, and high-voltage divider. A physically compatible PCB is not automatically an electrically compatible replacement. - Verify the exact board designation.
The ABB identification is KV A124:IPS DUAL. Do not substitute another KV variant merely because the board family name appears similar.

Procurement Check
Before approving an ABB 3BHE021951R0124, verify:
- Exact Product ID: 3BHE021951R0124
- Exact ABB designation: KV :IPS DUAL
- Catalog description: VOLTAGE SUBPRINT
- Host drive: ACS5000 Water Cooled, where documented
- Original board revision and markings
- Electrical drawing/reference designation in the inverter cabinet
- Associated IGCT power-supply and gate-drive arrangement
- Connector and mounting configuration
- Board condition and coating
- Whether the supplied item is the complete subprint or only a related assembly
- Functional test results before plant installation
Recommended procurement description:
ABB 3BHE021951R0124 / KV :IPS DUAL Voltage Subprint, Dual-Voltage IPS PCB for ABB Water-Cooled Medium-Voltage Drive Inverter.
The key distinction is that 3BHE021951R0124 is an ABB drive power-electronics voltage subprint, not a conventional automation I/O module. ABB’s product identification and the electrical parts list support that classification; unsupported reseller specifications for processor, memory, Ethernet, or generic input/output functions should be avoided.
