Description
xFANUC A06B-6120-H045 Power Supply Module (αi Series – PSM-45HVi)
The A06B-6120-H045 from FANUC is a high-capacity αi series power supply module (PSM-45HVi) used in CNC machine tools to generate and regulate DC bus power for servo and spindle amplifier systems.
Detailed Product Description (Website Ready)
The FANUC A06B-6120-H045 is a high-power CNC power supply module designed for the αi generation drive system. It converts 3-phase AC input (400–480V) into a stable DC bus voltage (~565–679V DC), which is then distributed to multiple servo and spindle amplifiers in the CNC machine.
This module is part of the PSM-45HVi class, typically used in large CNC machining centers and heavy-duty industrial automation systems, where multiple high-power axes and spindles require stable, high-capacity energy distribution.
It ensures smooth machine operation, high precision machining, and reliable performance even under continuous heavy load conditions.
Key Features & Benefits
