• ABB Part Number: 3BHB022793R0001
• Product Identification: ASE2 UD C920 AE01
• Product Type: Digital/control module; public supplier classifications are inconsistent, so verify the physical ABB nameplate before final asset classification.
• Associated Product Family: Reported in aftermarket documentation as an ABB UNITROL excitation-system component.
• Physical Dimensions: Approximately 300 × 126 × 45 mm (W × H × D) according to multiple supplier listings.
• Estimated Shipping Weight: Approximately 0.95–1.0 kg net; use the actual packed weight for freight calculations.
• What’s in the Box: ASE2UDC920AE01 module; mating connectors, mounting hardware, and documentation depend on the supplied configuration and condition.
• Storage Identification: Record the complete 3BHB022793R0001 part number, ASE2UDC920AE01 designation, serial number, and hardware revision.

Identification warning: Online listings disagree substantially about whether this unit is a digital module, digital-output module, communication module, controller, or power-supply module. The safest asset classification is therefore based on the complete ABB designation and physical nameplate, rather than unsupported reseller specifications.

Product Introduction

Architecture hook: The available technical evidence places ASE2UDC920AE01 / 3BHB022793R0001 within ABB’s industrial control ecosystem, with multiple current listings associating it with UNITROL excitation systems. One supplier specifically describes it as a communication and digital-control unit for UNITROL systems.

That association is more useful for maintenance planning than the generic reseller label “digital module.” UNITROL equipment is part of generator excitation and voltage-control infrastructure, so replacement hardware should be matched by exact part number and system configuration (especially where the spare is being held for a legacy excitation controller).

Published third-party data gives dimensions around 300 × 126 × 45 mm and weight around 0.95 kg, but ABB-authenticated mechanical documentation for this exact part was not located in the available sources. Treat these figures as logistics estimates, not cabinet-design dimensions

Core Technical Specifications

ABB ASE2UDC920AE01 3BHB022793R0001

Do not treat every value above as OEM-certified. The public sources are contradictory. For example, one listing calls the device a power-supply module and claims a 920 VDC output, while other listings identify the same part as a digital or communication/control module. Those conflicting descriptions are a strong reason to require an ABB datasheet, nameplate photograph, or system BOM before using electrical specifications for engineering.

For procurement records, 3BHB022793R0001 should be the primary traceability identifier, with ASE2UDC920AE01 retained as the corresponding ABB designation.

? Global Compliance & Industry Certifications

For an ABB excitation-system component, regulatory compliance should be evaluated within the complete UNITROL equipment configuration, not from generic marketplace listings.

Potential documentation may include:

• CE Mark — potentially applicable to the complete ABB system placed on the European market.
• UL / cUL — may apply to specific North American equipment configurations.
• IEC-based conformity — relevant to the applicable excitation/control equipment and installation.
• ATEX / IECEx — do not assume hazardous-area certification for this module unless the exact ABB configuration has the required certificate.
• Marine approvals such as DNV — applicable only where the complete equipment configuration has been certified for marine service.

For generator excitation equipment, certification and traceability matter because the hardware participates in electrical control functions where an undocumented substitution can affect system behavior, protection coordination, and commissioning records.

Verify specific lot certifications with OEM.

Retain the nameplate photograph, serial number, hardware revision, ABB part number, COO evidence, Certificate of Conformance, and applicable ABB declarations with the asset record.

? Long-Term Storage & Asset Preservation Guide

1. Keep the electronics in the original ESD shielding bag. Do not repeatedly remove the module for visual inspection. Protect connector pins and exposed circuit-board areas from static discharge and contamination.
2. Control humidity and condensation. Maintain a clean indoor storage environment, preferably below 60% RH. Avoid rapid temperature transitions, particularly when moving the spare from an air-conditioned warehouse into a hot and humid plant environment.
3. Preserve the complete identification chain. Record the 3BHB022793R0001 part number, designation, serial number, hardware revision, and date code. Store photographs with the warehouse record (this is particularly important given the contradictory third-party descriptions of this part).

Do not energize the unit simply to prove that a long-stored spare still works. Functional testing should follow the ABB/UNITROL service procedure and be performed by appropriately qualified personnel.

Physical Installation Prerequisites

• Install the unit only in the ABB system configuration for which the exact part number is specified.
• Confirm the rack, mounting frame, connector arrangement, and cable interface before installation.
• Do not assume DIN-rail compatibility from the module’s dimensions.
• Allow adequate clearance for connector engagement, cable routing, ventilation, and service access.
• Verify the cabinet grounding and equipotential-bonding arrangement before energization.
• Keep control and communication wiring separated from high-current power conductors where practical.
• Confirm the exact hardware revision against the UNITROL system BOM before replacing another module.
• Do not apply the reported 24 VDC supply figure as an engineering requirement until it has been verified against the applicable ABB documentation for the exact installation.

The published 300 × 126 × 45 mm dimensions are useful for preliminary shipping and shelf planning, but should not be used as the final cabinet-layout reference.

Buyer’s FAQ

Q: What HS tariff code should be used for 3BHB022793R0001?
A: Several aftermarket suppliers publish 8537101190, but this should be treated as a classification reference rather than a guaranteed customs classification. The final HS code should be confirmed against the actual function and construction of the supplied unit and the importing country’s tariff schedule.

Q: Does the Country of Origin need to match the seller’s country?
A: No. COO identifies the applicable manufacturing origin, not necessarily the seller’s location or shipping point. Some suppliers report Sweden, while another reports Switzerland or the USA for this same part number. Those discrepancies demonstrate why the COO should be verified from the actual unit and traceable documentation before customs filing.

Q: Should shipping insurance be purchased?
A: Yes, for international freight or high-value replacement shipments. The reported net weight is only around 1 kg, but the electronic assembly and connector interfaces can be damaged by impact or improper handling. Photograph the ESD packaging, carton, nameplate, and condition before dispatch.

Q: Does include the latest firmware pre-loaded?
A: Do not assume that it does. Available sources describe the unit as a digital/control or communication component, but none of the reliable material located establishes a universal firmware version for every 3BHB022793R0001 unit. If a supplier claims a specific firmware revision, request the exact ABB compatibility documentation and hardware-revision relationship before accepting the claim.
