Product Overview

The Allen-Bradley 80026-173-23-R is a high-performance internal power supply module specifically engineered for the PowerFlex 700 AC drive series. This DC-to-DC converter serves as a vital regulation point within the drive’s internal architecture, converting high-voltage bus power into a stabilized 24V DC output. This secondary voltage is critical for powering the drive's control circuitry, gate driver boards, and communication interface cards, ensuring that the drive's logical operations remain consistent regardless of input power fluctuations.

Designed for high-reliability industrial automation environments, the 80026-173-23-R is optimized to maintain system uptime in continuous process applications. It effectively bridges the power gap between the drive's high-power power stage and its sensitive electronic controls. By providing a clean and isolated voltage source, it prevents electromagnetic interference (EMI) from the motor switching stage from disrupting the drive's internal microprocessors.

Engineering Design and Environmental Resilience

A standout technical characteristic of the 80026-173-23-R is its conformal coated printed circuit boards (PCBs). This protective layer acts as a barrier against moisture, conductive dust, and corrosive airborne contaminants typical in chemical plants, paper mills, and heavy manufacturing facilities. This treatment significantly extends the module's MTBF (Mean Time Between Failures) and reduces the risk of short circuits in high-humidity or dusty environments.

The module features a compact, low-profile form factor that facilitates direct integration into the PowerFlex 700 chassis. Its thermal management system is designed for high efficiency, minimizing heat dissipation to prevent the elevation of internal drive temperatures. The 80026-173-23-R is a critical spare part for maintenance teams looking to restore drive functionality without replacing the entire inverter unit, providing a cost-effective path for lifecycle extension of legacy Rockwell Automation hardware.
