FANUC A06B-6110-H037 – Power Supply Module (PSM-37i) – Description
The FANUC A06B-6110-H037 is a high-capacity ALPHA i Power Supply Module (PSM-37i) used in FANUC CNC and servo/spindle drive systems. It is designed to convert incoming AC power into a stable DC bus supply, which is then distributed to servo amplifiers and spindle amplifier modules in CNC machines.
This module belongs to the FANUC ALPHA i power supply series (A06B-6110 family) and is widely used in medium to large CNC machining centers, including milling, turning, and multi-axis production machines. It operates on 200–240V AC three-phase input and delivers regulated DC output for stable and reliable machine operation.
The H037 variant is a high-power supply module (approx. 43 kW class), capable of supporting multiple servo axes and spindle drives simultaneously. It is commonly used in advanced CNC systems where consistent power distribution, high efficiency, and system stability are critical for continuous production.
According to technical specifications, it provides a DC output range of approximately 283–339V DC, with strong current capacity and built-in protection features for overvoltage, overcurrent, and thermal safety, ensuring reliable operation in demanding industrial environments.
Internally, it includes integrated control and power conversion circuitry with diagnostics, allowing monitoring of system health and ensuring stable operation of connected drive modules.
