Description
FANUC A06B-6120-H100 Power Supply Module (αi Series – PSM-100HVi)
The A06B-6120-H100 from FANUC is a high-capacity αi series power supply module (PSM-100HVi) used in CNC machine tools to generate and regulate the DC bus power required for servo and spindle amplifier systems.
Detailed Product Description
The FANUC A06B-6120-H100 is a high-performance CNC power supply module designed for the αi drive system, and it is one of the largest standard units in the A06B-6120 series. 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.
This module is widely used in large CNC machining centers and multi-axis industrial systems, where high power demand and continuous operation require a robust and stable energy supply. It supports synchronized operation of several axes and spindle drives through a shared DC bus architecture.
The H100 model is typically used in high-power machine configurations, making it suitable for heavy-duty cutting, multi-spindle systems, and large automated production lines.
