FANUCA06B-6087-H130-RAlpha Power Supply Module PSM-30, 3-Phase 200-230 V AC 127 A In, 283-325 V DC 35 kW Out

Product Description

What this part is

Fanuc A06B-6087-H130 is the Alpha series Power Supply Module model PSM-30. In a Fanuc Alpha drive rack this is the front-end converter, not a servo amplifier. It rectifies incoming three-phase mains into the common DC bus and supplies the 24 V DC control voltage that the servo amplifier modules (SVM) and spindle amplifier modules (SPM) alongside it draw from. The amplifiers turn that DC into motor current; the PSM does not drive a motor itself.

Order code breakdown

A06B: Fanuc servo and spindle products, covering drives, amplifiers and power supplies. 6087: the Alpha PSM power supply module family. H130: the size within that family, PSM-30, 35 kW class. -R, also written #R: a unit refurbished by Fanuc. Electrically and dimensionally it is the same PSM-30 as a plain A06B-6087-H130; the suffix records passage through Fanuc’s own repair route rather than a different model. Other suffixes seen on this family include #RS, #A, #CE and #EM.

Specifications in application

35 kW puts the PSM-30 at the larger end of the Alpha PSM range. Typical duty is a medium to large machining centre or lathe where a spindle amplifier and several axis amplifiers all hang off one DC bus. The PSM rating covers the sum of what the amplifiers on the bus draw at the same time rather than any one of them, and a PSM smaller than the machine was built with trips on heavy simultaneous acceleration.

The 127 A figure is the input current at 200 V, which sets the upstream protection and cabling. The input is three phase, with no single-phase option on this module.

The Alpha PSM is a regenerative front end: during deceleration the amplifiers push energy back into the DC bus and the PSM returns it to the mains rather than burning it in a resistor. An Alpha system therefore generally has no braking resistor, and regeneration depends on a healthy three-phase supply.

The 7-segment display on the front carries the alarm code, which is read against the Alpha power module alarm list. A share of PSM faults are bus, amplifier or supply-side problems reported by the PSM.

What is included

Power supply module only, as pictured. This listing does not include servo amplifier modules (SVM) or spindle amplifier modules (SPM); DC bus link bars or bus connection kits; input contactor, line filter, AC reactor or fuses; the connector kit or any of the control and interface cables; a battery; a braking resistor (an Alpha PSM is regenerative and does not normally use one); a rack, cabinet or mounting hardware; or documentation.

Mounting data

The module is enclosure-mounted, with the ventilation clearances specified by Fanuc. Approximate weight is 24 lb. A 35 kW converter is normally the cabinet’s largest thermal load. Supply voltage is 200–230 V three phase; a 400 V supply calls for a different module or a transformer. The amplifier and PSM configuration in the CNC parameters corresponds to the hardware fitted.

Interchange guidance

A06B-6087-H130, A06B-6087-H130-R, A06B-6087-H130R and A06B-6087-H130#R are the same PSM-30 module; the suffix records repair history and CE or regional build, not a specification change. Other H-numbers in the 6087 family are different power ratings and are not interchangeable. A06B-6087-H115 is the PSM-15 at 17.5 kW and 63 A, roughly half this module’s capacity, and is a related size rather than an equivalent. Also searched as A06B6087H130R, A06B 6087 H130, PSM-30, PSM30, Fanuc Alpha PSM 35kW, and GE Fanuc A06B-6087-H130. Sold as 1 piece.
