Description
FANUC A06B-6150-H018 Power Supply Module (αi Series – AiPS-18HV)
The A06B-6150-H018 from FANUC is an αi series power supply module (AiPS-18HV / PSM class) used in CNC machines to generate and regulate the DC bus power required for servo and spindle amplifier systems.
Detailed Product Description (Website Ready)
The FANUC A06B-6150-H018 is a medium-capacity CNC power supply module designed for the αi drive system. It converts 3-phase AC input (400–480V) into a stable DC bus voltage (~565–679V DC), which is distributed to servo and spindle amplifiers for machine axis control.
This module is commonly used in small to medium CNC machining centers and industrial automation systems, where reliable and efficient power conversion is required for continuous operation.
It belongs to the AiPS-18HV / PSM-18HVi class, making it a widely used standard power module in FANUC CNC configurations.
