FANUC A06B-6140-H030 Alpha i Power Supply Module

Overview

The A06B-6140-H030 is best positioned as a FANUC Alpha i power supply module rather than as a spindle or servo amplifier. Public industrial listings consistently describe it as a power supply module or servo power converter, and multiple sources identify it as aiPS-30 within the Alpha i power family.

In practical CNC cabinet architecture, a module like this serves a system-level role.

It supports the wider drive environment by handling the main incoming power and regenerative control function rather than controlling one axis directly.

That makes it especially important in machines where cabinet-level power continuity, regenerative energy handling, and overall drive stability must be preserved during service or replacement.

The public specification picture is also fairly consistent: 200–240 VAC three-phase input, 44 kVA main circuit equipment capacity, 0.7 kVA control power capacity, 35 kW rated output, regenerative control, and up to 64 kW motor output are all repeatedly associated with this model.

Those values make it clear that A06B-6140-H030 belongs to the larger Alpha i cabinet power class rather than to the small auxiliary power-supply category.

Key Specifications

FAQ

Q1: What kind of product is A06B-6140-H030?
It is a FANUC Alpha i power supply module. In practical CNC terms, it belongs to the cabinet power and regeneration side of the drive system rather than to the spindle or servo-axis amplifier side.

Public listings also commonly identify it as aiPS-30, which places it in the larger Alpha i power-supply family.

Q2: Why is regenerative control important in this model?
Regenerative control is important because it allows energy produced during deceleration or braking to be handled more efficiently than in a non-regenerative cabinet design.

In practical machine service, this matters because it helps define the module’s role in overall drive performance and shows that the unit is more than a simple incoming power converter.

Q3: What does the aiPS-30 designation tell the buyer?
It tells the buyer that the module belongs to the larger Alpha i power-supply class. For technical users, this is useful because it distinguishes the unit from smaller AiPS modules and confirms that the power-supply section of the machine is in a heavier cabinet-output range with 35 kW rated output and higher system-level responsibility.

Q4: Are the 44 kVA and 64 kW figures useful in practice?
Yes. These values help show the scale of the module and confirm that it belongs to a substantial CNC cabinet power class rather than to a small support supply.

For maintenance engineers, that makes it easier to distinguish the H030 from smaller Alpha i power modules and match it correctly to the installed machine.

Q5: What should buyers verify before ordering?
Buyers should verify the exact part number, the aiPS-30 family context, the cabinet’s incoming power class, and the regenerative power architecture of the machine.

For FANUC power supply modules, correct system role and cabinet-level compatibility are usually more important than broad category similarity.
