Description
FANUC A06B-6120-H030 Power Supply Module (αi Series – PSM-30HVi)
The A06B-6120-H030 from FANUC is an αi series high-capacity power supply module (PSM-30HVi) used in CNC machine tools to generate and regulate the DC bus power required for servo and spindle amplifier systems.
Detailed Product Description (Website Ready)
The FANUC A06B-6120-H030 is a high-performance 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), which is then distributed to servo and spindle drives for precise motion control.
This module is widely used in medium to large CNC machining centers, where multiple servo axes and spindle systems require stable, high-capacity power distribution. It ensures smooth machine operation, accurate positioning, and reliable spindle performance even under heavy industrial loads.
It is part of the PSM-30HVi class, which is commonly used in multi-axis CNC configurations and automation systems requiring continuous-duty operation.
