Description
xFANUC A06B-6120-H075 Power Supply Module (αi Series – PSM-75HVi)
The A06B-6120-H075 from FANUC is a high-capacity αi series power supply module (PSM-75HVi) used in CNC machines to generate and regulate the DC bus power required for multiple servo and spindle amplifiers.
Detailed Product Description
The FANUC A06B-6120-H075 is a high-power CNC power supply module designed for the αi drive system, used in medium to large industrial machining centers. It converts 3-phase AC input (400–480V) into a regulated DC bus voltage (~565–679V DC), which is distributed to servo and spindle drives.
This module is part of the PSM-75HVi class, one of the higher-capacity units in the A06B-6120 series. It is typically used in heavy-duty CNC systems with multiple high-power axes and spindle configurations, where stable and continuous energy supply is critical.
It supports synchronized operation of multiple servo amplifiers and ensures smooth machining performance under high load conditions.
Key Features & Benefits
Ultra High Power Capacity (PSM-75HVi Class)
Designed for demanding CNC systems requiring large-scale power distribution.
High Output Power (~80 kW Class)
Capable of supplying power for large multi-axis CNC machines and spindle systems.
Stable DC Bus Output
Provides regulated ~565–679V DC, ensuring consistent servo and spindle performance.
400–480V 3-Phase Input
Compatible with standard industrial power systems used in manufacturing plants.
Multi-Drive Support
Used to power multiple servo and spindle amplifiers through a shared DC bus architecture.
Industrial Cooling Design
Built with forced-air cooling and heavy-duty heat management for continuous operation.
