Description
FANUC A06B-6120-H011 Power Supply Module (αi Series – PSM-11HVi)
The A06B-6120-H011 from FANUC is an αi series power supply module (PSM-11HVi) used in CNC machine tool systems to generate and regulate the DC bus power required by servo and spindle amplifiers.
Detailed Product Description (Website Ready)
The FANUC A06B-6120-H011 is a high-voltage CNC power supply module designed for the αi generation drive system. It converts 3-phase AC input (typically 400–480V) into a stable DC bus voltage (~565–679V DC) used to power FANUC servo and spindle amplifiers.
This module is responsible for supplying clean, regulated, and high-efficiency power distribution across multiple CNC axes, ensuring smooth machine motion, precise positioning, and stable spindle performance.
It is commonly used in medium-capacity CNC machining centers, milling machines, and automated production systems, where reliable power conversion is essential for continuous industrial operation.
