The A06B‑6140‑H026 serves as the central DC bus‑power source for Fanuc αi‑series servo drive cabinets, feeding multiple servo‑amplifier modules in the same rack. With 200–240 V AC 3‑phase input at 50/60 Hz, it rectifies and regulates the power to a 283–339 V DC bus that is shared across several servo drives, enabling synchronized, high‑performance multi‑axis control. The module is rated for 29.8 kW output power and 106 A current at 200 V, making it suitable for high‑power machining centers, turning machines, and robot‑axis clusters.
This Fanuc Alpha i power supply incorporates low‑loss power devices, active or passive cooling, and comprehensive protections such as overcurrent, overvoltage, and overtemperature safeguards, ensuring reliable operation in continuous‑duty environments. Its compact, panel‑mountable design allows integration into standard CNC control cabinets, and it is typically sold as an original Japan‑made module with a 12–24‑month warranty for new units and 3‑month warranty for tested or used modules. Because it directly powers multiple servo amplifiers, the A06B‑6140‑H026 is a common replacement item for CNC drive‑rack servicing and rebuilds.
