FANUC A06B-6140-H026 Alpha i Power Supply Module

Overview

The A06B-6140-H026 is a FANUC Alpha i power supply module commonly identified as AiPS-26.

Product listings consistently describe it as a 200–240 V input power unit with 29.8 kW power rating, 106 A at 200 V current rating, and 283–339 V rated output, which places it in the higher-capacity section of the Alpha i cabinet power architecture.

What gives this model real value in the field is not just output size.

A power supply module at this level usually sits near the center of the drive cabinet’s electrical structure, feeding the wider motion system that spindle and servo hardware depend on.

In practice, that means buyers usually search for this part when they need to restore the original cabinet power stage cleanly, not when they are experimenting with substitutes. That application view is an engineering inference based on the model’s published AiPS-26 class and output range.

Technical Data

Application Value

The A06B-6140-H026 is best suited to installed FANUC Alpha i systems, CNC machine tools, and drive cabinets where a higher-capacity DC bus supply is already part of the machine design.

In those environments, a module like this is valuable because it supports the original power-distribution structure without forcing a redesign of the cabinet’s supply side. That often matters more than broad “high performance” wording, especially in maintenance-driven purchasing. 

This is an engineering inference based on the model’s published power class and Alpha i positioning.

It is also a practical choice in rebuild and spare-parts planning. When a machine has already been engineered around a specific Alpha i power-supply family, keeping the same model class usually makes restart work cleaner and more predictable.

That can reduce follow-up troubleshooting on the downstream drive side because the original supply characteristics are preserved rather than approximated.

This is an engineering inference from the model’s replacement-market use and consistently published electrical range.

Replacement and Maintenance Perspective

For service work, the A06B-6140-H026 should be treated as a system-level cabinet power module, not just as a box with the right voltage label.

The input class, output range, power class, and cabinet fit all matter.

In real industrial maintenance, exact continuity at the power stage is often more valuable than trying to replace the unit with something electrically “close,” because the rest of the drive chain depends on that supply behavior. 

This is an engineering inference based on the model’s published power and output specifications and the way it is sold into installed-base support.

FAQ

Q1: What kind of product is A06B-6140-H026?
It is a power supply module in the FANUC Alpha i family, commonly identified as AiPS-26 for CNC and drive-cabinet use.

Q2: Why is this module important in a motion-control cabinet?
Because it supports the cabinet power stage that the wider drive system depends on.

In practical machine service, problems at the supply level can affect much more than one component, which is why exact replacement is usually preferred.

This is an engineering inference based on the model’s published role and output class.

Q3: What applications fit this module best?
It fits CNC machine tools, Alpha i drive cabinets, and installed FANUC motion systems that already use this power-supply class.

These applications are inferred from the published electrical class and family positioning.

Q4: Why do input and output ranges matter so much here?
Because the supply module has to match the electrical architecture already built into the cabinet.

The input range, DC output range, and power class affect how the rest of the drive hardware is supported. 

This is an engineering inference based on the model’s published 200–240 V input and 283–339 V output data.

Q5: What should be checked before ordering A06B-6140-H026?
Check the installed part number, cabinet supply class, output-bus requirements, and the surrounding Alpha i hardware.

Those checks usually matter far more than appearance alone.
