FANUC A06B-6110-H037 | Factory-Sealed Spare

Unboxing & Physical Snapshot

• Brand / Model: FANUC A06B-6110-H037, Alpha-i PSM-37i Power Supply Module. FANUC documentation lists H037 specifically as the PSM-37i in the 200-V input Alpha-i series.
• Physical dimensions: Approximately 150 × 290 × 380 mm (W × H × D) based on a published product specification. Treat these as logistics dimensions; confirm the cabinet mechanical drawing before installation.
• Estimated module weight: Approximately 10.7 kg. Published sources report 10.0–11.0 kg, so use the actual measured packed weight for freight calculations.
• What’s in the box: PSM-37i power supply module; mounting hardware and documentation only if explicitly included in the purchase configuration.
• Internal hardware reference: The PSM-37i uses the A16B-2203-0632 power board in the documented Alpha-i architecture.
• Handling warning: This is a high-power industrial converter. Keep the unit secured during unpacking and never lift it by wiring, connectors, or PCB-access components.

Product Introduction

The A06B-6110-H037 sits at the high-power end of FANUC’s 200-V Alpha-i drive architecture. It is the PSM-37i, a power supply module that feeds the DC bus for compatible Alpha-i servo and spindle amplifier configurations. FANUC’s ordering documentation identifies it alongside the PSM-5.5i, PSM-11i, PSM-15i, PSM-26i, and PSM-30i units.

This is not a small control-board spare. The published rating reaches 43 kW, with three-phase 200–230 VAC input and approximately 283–325 VDC output. The module also contains high-energy capacitors and cooling hardware (which makes electrical isolation, discharge procedures, and lifting arrangements part of the physical asset-control process).

Core Technical Specifications

FANUC A06B-6110-H037

The 43 kW rating is the critical asset-identification parameter. Published technical references consistently identify H037 as the PSM-37i with 200–230 VAC three-phase input and approximately 43 kW output.

Do not substitute a PSM-30i or PSM-55i merely because its enclosure appears similar. The input-current rating, DC-bus capacity, associated servo/spindle amplifier configuration, and CNC system compatibility must all be checked against the FANUC electrical documentation.

? Global Compliance & Industry Certifications

The A06B-6110-H037 is industrial CNC drive power hardware, but its certification status must be established from the specific unit and applicable FANUC documentation.

• CE Mark: Verify the nameplate and applicable FANUC conformity documentation for the exact revision.
• UL/cUL: Do not assume a standalone UL/cUL listing without product-specific evidence.
• ATEX/IECEx: Not to be presumed. The PSM-37i should not be treated as certified hazardous-area equipment merely because it is industrial automation hardware.
• Marine approvals: DNV GL or equivalent marine certification should only be claimed when the exact configuration has documented approval.
• EMC compliance: The final machine or CNC cabinet installation remains relevant to EMC performance; cabinet grounding, cable routing, filters, and enclosure construction can affect system compliance.
• Electrical safety: The approximately 283–325 VDC DC bus presents a serious stored-energy hazard after AC power has been removed. The service procedure must account for capacitor discharge before access.

A Class I Division 2 or ATEX rating cannot be inferred from the Alpha-i product family. If the equipment will be installed in a classified location, verify the complete cabinet assembly and applicable certification, not merely the drive module.

Verify specific lot certifications with OEM.

? Long-Term Storage & Asset Preservation Guide

Control the environment first. FANUC-related specifications indicate storage temperatures around -20°C to +60°C and humidity up to 95% non-condensing; for multi-year spare storage, maintain a much drier warehouse condition where practical and prevent condensation.

Protect the cooling system. Keep the module sealed against dust and industrial contaminants, particularly around the internal and external fan assemblies. Do not rotate or electrically energize the cooling fans merely as a routine storage exercise; inspect fan bearings and blades during incoming inspection instead.

Pay special attention to the DC-link capacitors. This module handles a high-voltage, high-power DC bus. For a spare that has remained unused for many years, do not simply install and energize it at full system load without following the applicable FANUC commissioning procedure; capacitor condition and precharge behavior should be verified by qualified personnel.

Retain the serial number, date code, hardware revision, original packaging, inspection records, and any repair history with the asset. That record becomes particularly valuable when an older CNC system has several visually similar Alpha-i power modules.

Physical Installation Prerequisites

• Install only within the FANUC Alpha-i drive architecture for which the PSM-37i is specified.
• Verify the associated SVM/SPM combination and total DC-bus power requirement before replacement.
• Provide the specified three-phase 200–230 VAC input arrangement and appropriate upstream protection.
• Size conductors, disconnects, protective devices, and cabinet power components for the high input current; the published rating is 150 A at 200 V.
• Provide sufficient forced-air cooling around the heat-producing assembly and keep the fan inlet/outlet paths unobstructed.
• Allow physical clearance for the approximately 150 × 290 × 380 mm enclosure plus power wiring and service access.
• Secure the approximately 10.7 kg module properly before connecting busbars or cables.
• Bond the module/cabinet to protective earth according to the FANUC installation documentation.
• Keep high-power input/output wiring separated from low-level CNC signal and feedback wiring.
• Before service, isolate incoming power and follow the FANUC discharge procedure for the DC bus and capacitors.
• After installation, verify alarms, precharge behavior, DC-bus voltage, cooling-fan operation, and the connected servo/spindle amplifier configuration before returning the machine to production.

Buyer’s FAQ

What HS tariff code should be used for the A06B-6110-H037?

Do not assign an HS code solely from the part number. The PSM-37i is a CNC servo-drive power supply/converter, so classification should be reviewed against the importing country’s tariff schedule and the equipment’s declared function. Have the customs broker validate the final classification before issuing the commercial invoice.

Does Country of Origin affect this spare?

Yes. COO must be established from the actual unit and supporting traceability records. One commercial listing identifies Japan as the country of origin, but that information should not be copied into a customs document without verifying the specific unit being shipped.

Should this 10+ kg power module be shipped with insurance?

For an international shipment, insurance is prudent. Record the serial number, photograph the power connectors and enclosure before packing, use impact-resistant internal cushioning, and specify the actual commercial value. Because the module weighs roughly 10–11 kg, packaging must also prevent movement inside the carton or wooden case.

Does A06B-6110- contain the latest firmware?

Do not treat it as a firmware-defined controller. This is a PSM-37i power supply module. The important compatibility factors are the Alpha-i drive generation, CNC control, associated SVM/SPM modules, electrical configuration, and hardware revision. FANUC documentation identifies as the PSM-37i and links it to the corresponding power-board architecture.

For inventory control, record the full part number, suffix, serial number, hardware revision, and any board-level identification rather than using “PSM-37i” alone.
