1. Product Overview

The Allen-Bradley 80026-173-23-R Power Module is an industrial DC/DC power supply designed for applications requiring dependable power conversion within industrial automation and drive-related equipment. Manufactured under the Allen-Bradley and Rockwell Automation product portfolio, this module is identified as a DC/DC power supply with conformal-coated circuit boards.

Stable power conversion is essential to industrial control systems because electronic control assemblies depend on appropriate voltage levels to operate correctly. A power module that delivers suitable DC power helps support control electronics, internal power distribution, and the reliable operation of associated equipment. In demanding industrial environments, protection against moisture, dust, and other contaminants can also be an important consideration when selecting power conversion components.

The 80026-173-23-R is relevant to maintenance and spare-parts planning for existing industrial installations. When an original power module becomes unavailable through standard distribution channels, identifying the exact part number, revision, electrical configuration, and physical connections is important for avoiding compatibility issues during replacement.

This model should be distinguished from other Allen-Bradley power modules with similar part numbers. In particular, the 80026-172 series and 80026-173 series should not be treated as interchangeable without confirming their electrical specifications and intended applications.

2. Technical Specifications

The dimensions and weight listed above are the supplied product data and should be confirmed against the actual unit before shipment, enclosure planning, or installation.

Detailed electrical specifications—including nominal input voltage, output voltage, maximum output current, rated power, allowable operating temperature, and connector assignments—must be checked against the nameplate and documentation for the exact 80026-173-23-R configuration. These values should not be inferred from a similar-looking model.

3. Function and Working Principle

3.1 DC-to-DC Power Conversion

A DC/DC power supply converts electrical energy from one DC voltage level to another suitable level for the connected equipment. Depending on its design, the conversion circuit may use high-frequency switching, energy-storage components, feedback regulation, and output filtering to achieve the required electrical characteristics.

For an industrial power module, the main objective is to provide an appropriate DC supply to the equipment for which it was designed. Correct voltage regulation and current capacity help ensure that downstream electronic assemblies receive power within their specified operating limits.

The exact conversion topology and electrical ratings of the 80026-173-23-R should be verified using model-specific documentation.

3.2 Voltage Regulation

Industrial control electronics can be sensitive to variations in supply voltage. A properly specified power module helps maintain the voltage required by connected circuits under normal operating conditions.

Voltage regulation is important because unstable or incorrect power can cause unexpected equipment behavior, communication interruptions, control faults, or equipment shutdowns. A replacement module must therefore match the original unit’s required input and output characteristics rather than merely fitting into the same enclosure.

3.3 Protection of Electronic Components

The product description identifies conformal-coated circuit boards. Conformal coating is a protective layer applied to electronic assemblies to help reduce the effects of certain environmental contaminants, such as moisture and dust, depending on the coating material and construction.

This feature can be valuable in industrial settings where electrical equipment is exposed to less-than-ideal environmental conditions. However, conformal coating does not make a power module immune to liquid ingress, condensation, chemical exposure, excessive heat, or improper installation. The actual environmental limits must be confirmed from the applicable product documentation.

3.4 Power Distribution Within Industrial Equipment

In an industrial drive or control cabinet, the power supply forms part of a larger electrical system. It works alongside other components that may include control boards, signal-processing circuits, communication interfaces, protection devices, and cooling equipment.

The module must be correctly matched to the receiving system so that its electrical output, wiring arrangement, and protection requirements are appropriate for the application.

4. Role in Industrial Control Systems

4.1 Supporting Drive-System Electronics

Industrial drive systems combine power conversion, motor control, monitoring, and protective functions. Their electronic control assemblies require a compatible source of power to operate reliably.

A suitable power module contributes to the electrical infrastructure supporting these assemblies. If the power supply fails or delivers an unsuitable output, the affected equipment may generate faults or become unavailable.

For existing installations using the 80026-173-23-R, maintaining an accurate spare-parts record helps reduce the time required to identify the correct replacement.

4.2 Improving Maintenance Efficiency

When an industrial system stops because of a power-related fault, maintenance personnel must identify the affected circuit and determine whether the power module is responsible. Correct model identification, clear wiring records, and access to the applicable technical documentation can simplify this process.

Keeping the exact part number in maintenance records also helps prevent accidental substitution with a module from a similar product family.

4.3 Supporting Existing Equipment

Older industrial installations may remain operational for many years after their original components reach the end of their normal sales lifecycle. Replacing a failed component with a verified compatible unit can help preserve the existing system configuration and avoid a larger retrofit.

The 80026-173-23-R may therefore be relevant to maintenance programs for equipment already designed around this specific module. Compatibility must be established using the installed equipment’s documentation and the module’s identification details.

5. Industrial Applications

The following are general application contexts for compatible DC/DC power supplies. They should not be interpreted as a manufacturer-confirmed list of applications exclusive to the 80026-173-23-R.

5.1 Industrial Drive Cabinets

Drive cabinets contain electronic assemblies that support motor control, system monitoring, and internal power distribution. A compatible DC/DC power supply can form part of the power architecture required by these assemblies.

When replacing a module, technicians should verify the original equipment model, electrical ratings, terminal layout, and mounting arrangement.

5.2 Manufacturing and Processing Facilities

Manufacturing facilities often depend on integrated electrical and automation equipment to maintain continuous production. Power supply faults can interrupt the operation of associated machinery and increase maintenance requirements.

Using a correctly specified replacement module helps maintenance teams preserve the designed electrical configuration of the equipment.

5.3 Heavy Industrial Equipment

Industrial environments may expose electrical assemblies to vibration, airborne particles, temperature fluctuations, and other operating stresses. A power module with conformal-coated circuit boards may provide an additional level of protection against certain contaminants.

Actual suitability for a particular environment depends on the module’s rated operating conditions and the enclosure in which it is installed.

5.4 Legacy Automation Systems

Legacy systems frequently require carefully managed spare parts because changing a single electrical component can affect the compatibility of the overall assembly.

For installations that specify the 80026-173-23-R, retaining a verified spare and documenting its revision can help maintenance teams respond more efficiently to unexpected failures.
