- Part Type: Gate Unit Power Supply / Drive Power Module
- ABB Type Designation: S KU C755 AE105:GUSP
- Weight: Approximately 2.36 kg according to one current product listing
- Application: ABB drive power electronics and gate-unit systems
Technical Introduction
The ABB KUC755AE105 / 3BHB005243R0105 is identified as a Gate Unit Power Supply (GUSP) associated with ABB drive power electronics. ABB-related parts references pair KUC755AE105 directly with 3BHB005243R0105.
This part should be treated as a drive power module rather than a generic control-system power supply. The ABB type designation is listed as S KU C755 AE105:GUSP, with the catalog description “GATE UNIT POWER.” For a replacement order, matching the complete ABB part number and type designation is more reliable than matching the enclosure or connector arrangement alone.
Best Suited For
- ABB drive maintenance and corrective repair
- Replacement of failed gate-unit power hardware
- Spare inventory for legacy ABB power-electronics equipment

The available product documentation does not provide sufficient authoritative information to establish the complete input/output electrical ratings, dimensions, operating temperature, or connector pinout. Those values should be confirmed against the applicable ABB drive documentation before installation.
Field Engineer’s Tech Notes
- Do not treat this as a universal drive power supply. KUC755AE105 is specifically identified as a gate-unit power component. Confirm the associated drive hardware and GUSP designation before substituting another ABB power module.
- Check the DC-side power path before installing a replacement. A failed gate-unit supply can be a symptom rather than the original fault. Inspect associated gate-unit wiring, connectors, semiconductor power-stage components, and signs of overtemperature or insulation damage before energizing the replacement.
Adaptive QA & Testing Protocol
Testing begins with identification verification against 3BHB005243R0105 / KUC755AE105, followed by PCB and connector inspection for corrosion, contamination, cracked components, damaged terminals, and heat-related discoloration.
Where the appropriate ABB drive test equipment is available, the unit is checked as part of the gate-unit power circuit rather than through a simple standalone power-on test. Output stability, connector integrity, and associated gate-unit operation should be verified against the applicable drive service documentation.
Test reports, inspection photographs, and available test videos can be provided upon request.
