The FANUC A06B-6200-H037 is an αiPS 37-B power supply module used in compatible FANUC αi-B servo and spindle drive systems.

FANUC documentation classifies this model as a standard 200V-series αiPS-B power supply. It provides DC-link power for compatible servo and spindle amplifier modules within a modular FANUC CNC drive configuration.

The A06B-6200-H037 is commonly listed in organic search results as a:

• FANUC αiPS 37-B Power Supply Module
• FANUC Servo Power Converter
• FANUC CNC Converter
• Alpha i-B Power Supply Unit

These keyword variations reflect how industrial maintenance customers search for the same module online.

A recent FANUC system data sheet lists a 37kW continuous output, 45kW maximum output, 118kW peak output, and 54kVA power-supply requirement for the A06B-6200-H037. It also gives a reference weight of 8.3kg and module dimensions of approximately 380 × 150 × 272mm.

Published nameplate-style specifications consistently show a 200–240VAC, three-phase, 50/60Hz input, a listed input current of 154A, and a 283–339VDC, 44kW output specification.

The module is suitable for replacement when a confirmed power-supply fault causes DC-link loss, failure of connected amplifier modules to start, power-converter alarms, abnormal status indications, or unstable operation across the drive system.

The continuous, maximum, and peak output ratings follow FANUC technical data. The 154A input and 44kW DC-output values are retained as published nameplate-style specifications supported by multiple specialist product pages.

Technical Clarification

The model designation αiPS 37-B corresponds to the module’s 37kW continuous output rating in FANUC technical data.

The 44kW figure appearing on product labels and replacement-parts pages is a published DC-output specification. FANUC’s more detailed performance data separately identifies:

• Continuous Output: 37kW
• Maximum Output: 45kW
• Peak Output: 118kW

For a technically accurate product page, these values should remain separately labeled rather than describing the unit simply as a “44kW power supply.”

Compatibility Note

The A06B-6200-H037 belongs to the standard αiPS-B series. FANUC separately lists A06B-6202-H037 as the level-up version of the αiPS 37-B, so the two complete order specifications should not be treated as automatically interchangeable.

Before ordering, please verify:

• Complete FANUC part number
• Model marking αiPS 37-B
• A06B-6200 or A06B-6202 specification
• 200V-class three-phase input requirement
• Connected servo and spindle amplifier models
• Total continuous and peak system demand
• AC reactor and magnetic-contactor configuration
• Original terminals and connector arrangement
• Hardware revision and existing alarm information

Selection of the power-supply module should be based on the complete FANUC drive configuration rather than appearance or the αiPS model name alone.

Common Use Cases

• FANUC αiPS 37-B power-supply replacement
• CNC servo and spindle drive-system maintenance
• Troubleshooting DC-link power or converter alarms
• Repair of a module that cannot start connected amplifiers
• Diagnosis of unstable power across multiple drive modules
• Replacement of damaged converter or regenerative circuitry
• Preparation of a tested spare power-supply module
