The A06B‑6087‑H126 servo amplifier power supply module is an original Fanuc component engineered to serve as the DC bus power source for Fanuc servo amplifier racks in CNC machines and industrial automation cells. It takes a three‑phase 200–230 VAC input at 50 Hz and converts it into a regulated DC bus voltage between 283–325 V, which is shared across multiple Alpha or α‑series servo amplifiers in the same cabinet.
This power supply module delivers an impressive 29.8 kW output power, making it suitable for multi‑axis machines that require several servo drives to operate simultaneously. It is built with robust components and advanced thermal design, providing current limiting, overvoltage, and overtemperature protection to ensure safe and reliable operation under heavy‑load industrial conditions.
Physically, the A06B‑6087‑H126 features DIN‑rail mounting, enabling compact installation in standard industrial control cabinets and simplifying panel layout. It is manufactured in Japan under Fanuc‑quality standards and is accompanied by the manual number B‑65162, which provides detailed instructions for installation, wiring, operation, and maintenance. The unit is widely used in manufacturing, automotive, aerospace, CNC machining centers, robotics, and automated production lines where a centralized, high‑reliability servo bus‑power source is required.
