Product Overview

The Allen-Bradley 80026-173-23 (also cataloged as 80026-173-23-R) is a high-efficiency, 100% brand new original switching DC/DC power supply module engineered exclusively for the PowerFlex 700 AC drive infrastructure. This heavy-duty power regulation card mounts directly inside the drive chassis, converting fluctuating internal bus voltage into highly stable, isolated DC voltage rails. By simultaneously supplying specific power lines to sensitive main control boards, interface circuitry, and internal cooling fans, this module acts as the foundational power heart that stabilizes drive logic execution and prevents processing glitches during heavy industrial motor control cycles.

Engineering Advantages

The 80026-173-23 switching power supply directly resolves critical thermal, environmental, and signal integrity pain points encountered in heavy industrial manufacturing installations:

• Combats High-Humidity and Corrosive Vapors: Paper mills, wastewater treatment plants, and chemical processing facilities expose drive electronics to aggressive ambient elements like hydrogen sulfide, moisture, and fine dust. The 80026-173-23 features high-spec conformal-coated circuit boards that insulate sensitive traces, preventing premature chemical corrosion, parasitic electrical tracking, and catastrophic short-circuits.

• Simplifies Maintenance via Direct Drive Chassis Integration: Mounting separate, non-native DIN-rail power supplies to run drive controls requires extensive panel restructuring, external wiring, and extra cabinet real estate. This module utilizes a custom compact footprint shaped exactly for direct, internal slot replacement inside the standard PowerFlex 700 enclosure, restoring full factory operation without altering the cabinet layout.

• Suppresses Severe Line Harmonics and Electrical Surges: Heavy industrial grids experience frequent voltage spikes, dips, and harmonic distortions from nearby welding bays or large motor starts. The module incorporates robust input filters paired with heavy-duty MOV transient suppression to block electrical line noise, protecting down-circuit microprocessors from voltage strain and unprovoked drive faults.

• Optimizes Thermal Management in Hostile Cabinet Environments: High ambient operating temperatures inside sealed factory control panels degrade standard power components rapidly. By implementing advanced high-frequency switching regulators alongside top-tier capacitors rated up to 105 degrees Celsius, this power supply minimizes internal heat dissipation and ensures stable 552W multi-rail delivery even under continuous peak-load operations.

FAQs

• Q: Is this Allen-Bradley 80026-173-23 power supply unit a brand new item?A: Yes. We supply this product exclusively as a 100% brand new, original factory component in pristine condition. It includes our full comprehensive warranty to ensure reliable operation and seamless integration into your existing PowerFlex automated repair loops.

• Q: Can I use this power supply as a general-purpose 24V supply on a standard DIN rail?A: No. Allen-Bradley engineered the 80026-173-23 specifically for the PowerFlex 700 series AC drive housing. Its internal dimensions, custom multi-rail output architecture (+5V, +/-15V, +12V, +/-24V), and specialized electrical connection interfaces make it incompatible with standard external DIN-rail mounting formats.

• Q: What outputs are available on this module to power drive sub-assemblies?A: This multi-rail switching module generates precise DC voltage levels to run all internal drive sections. The unit supplies clean power simultaneously to the main control boards, human-machine interface (HMI) modules, communication option cards, and the drive’s high-velocity 12V/24V cooling fans.

• Q: How does galvanic isolation inside this module preserve plant safety?A: The module establishes a complete physical galvanic isolation barrier between the dangerous high-voltage input lines and the low-voltage control circuitry. This barrier blocks high-voltage spikes from jumping onto the user-accessible control terminals, saving the main processor cards from frying and protecting plant technicians from hazardous shocks.
