Product Overview

The Allen-Bradley 80026-088-01-R is a high-performance, 300-watt AC/DC switching power supply designed specifically for the PowerFlex® drive family and integrated ControlLogix® systems. This module serves as a centralized power hub, converting standard 120/240V AC line voltage into multiple regulated DC rails. By providing simultaneous outputs of 5V, 12V, and 24V DC, the 80026-088-01-R eliminates the need for multiple independent power sources, streamlining control cabinet architecture and improving overall system reliability.

Engineered for the rigorous demands of industrial automation, this switching power supply maintains a 90% efficiency rating. This high efficiency minimizes thermal load within the enclosure, extending the operational lifespan of sensitive internal electronics. The 80026-088-01-R is a critical component for maintaining the "brain" of a drive system, ensuring that logic controllers, interface modules, and cooling fans receive clean, uninterrupted power.

Key Technical Characteristics

The 80026-088-01-R is distinguished by its protective circuitry and versatile output capabilities.

• Triple-Rail Output: Delivers stabilized 5V DC for logic circuits, 12V DC for auxiliary peripherals, and 24V DC for standard industrial I/O and relay control.

• Global Voltage Compatibility: Features a flexible input stage that accommodates both 120V and 240V AC infrastructures, suitable for international deployment.

• Integrated Surge Mitigation: Built-in hardware-level surge protection shields downstream components from voltage transients and spikes common in heavy industrial environments.

• Optimized Thermal Management: Operates with minimal energy loss, resulting in lower heat dissipation and reducing the requirement for aggressive active cooling.

• Compact Integration: The small-form-factor design allows for easy mounting within dense ControlLogix chassis or PowerFlex drive enclosures without sacrificing valuable space.
