Description

Product Overview

The Allen-Bradley 80026-173-23-R is a specialized DC/DC power supply module engineered specifically for the PowerFlex 700 series of high-performance AC drives. This component converts internal bus voltage into a regulated 24V DC output to sustain critical control logic and interface circuitry.

High-Efficiency Power Conversion

The 80026-173-23-R serves as the primary energy management interface within the drive’s internal architecture. By utilizing advanced switching regulator technology, the module provides a stable 24V DC supply even during fluctuations in the primary input power. This stability prevents logic errors and unexpected drive trips, ensuring that the motor control parameters remain consistent under varying load conditions. Furthermore, the high-efficiency design minimizes heat dissipation within the drive chassis, which preserves the life of neighboring electrolytic capacitors and sensitive semiconductors.

Environmental Resilience and Protection

To ensure reliable operation in heavy industrial settings, the 80026-173-23-R features factory-applied conformal coating on all printed circuit boards.² This protective layer acts as a barrier against moisture, conductive dust, and corrosive chemical vapors commonly found in paper mills and wastewater facilities. Because this coating prevents parasitic leakage currents and hardware corrosion, the module maintains superior electrical isolation throughout its service life. This focus on durability significantly reduces the frequency of maintenance interventions and lowers the total cost of ownership for the drive system.

Integration and System Longevity

The modular design of the 80026-173-23-R allows for direct integration into existing PowerFlex 700 frame sizes. Its compact physical footprint facilitates easy replacement during routine upgrades or emergency repairs, effectively minimizing system downtime. Additionally, the module includes integrated over-voltage and short-circuit protection, which safeguards the drive’s main control board from downstream electrical faults. By maintaining the integrity of the control power bus, the 80026-173-23-R ensures the long-term operational health of the entire automation suite.
