Features:
- The complete board identity combines ABB article 3BHE035301R0410 with type UNS0121 A-Z,V1. Available public ABB family documentation does not support generic supply, current or temperature claims for this exact PCB.
- Match both codes, PCB revision V1, component population, connector keying, firmware/configuration and the receiving UNITROL cabinet drawing.
- Use it only in the excitation-control position documented by the installed generator system parts list.
3BHE035301R0410 UNS0121 A-Z,V1 is selected from the complete manufacturer identity and receiving-system evidence. Back up settings, photograph connectors/jumpers, isolate excitation sources and use ESD controls before removing the board. Confirm board power and diagnostics, then verify sensing, field-command, regulator, limiter and alarm behavior through controlled commissioning.

3BHE035301R0410 UNS0121 A-Z,V1 official technical documentation and verified Moore Automated resources.
Important Notice: Confirm the complete model, article number and installed configuration before replacement. All links open in a new page.
Use both identifiers and the V1 hardware revision when comparing the replacement board.
Confirm sensing, field-command, limiter and alarm connectors from the generator schematic.
Restore settings and prove stable regulation and protection response before normal loading.
