FANUC A06B-6140-H015 – Power Supply Module (aiPS-15) – Description
The FANUC A06B-6140-H015 is a reliable ALPHA i Power Supply Module (aiPS-15 / PSM-15i) used in FANUC CNC and servo drive systems. It is designed to convert incoming AC power into a stable DC bus supply, ensuring efficient and consistent operation of connected servo and spindle amplifier modules.
This unit belongs to the A06B-6140 series (second-generation ALPHA i power supplies) and is commonly used in CNC machining centers such as milling and turning machines. It operates on 200–240V AC three-phase input and delivers a regulated DC output (approx. 283–339V) to support drive systems.
The A06B-6140-H015 is typically used in medium-power CNC configurations (~15–19 kW class) and plays a critical role in maintaining stable machine performance, efficient power distribution, and protection of connected drive components.
