Product Overview
The Allen-Bradley 80026-524-01-R is a 1500 W single-phase AC/DC power supply manufactured by Rockwell Automation for industrial drive and motion control systems. Catalogued on the Rockwell product page as a 1500 W 1PH AC/DC POWER SUPPLY with an active lifecycle status and a repairable/replaceable service classification, the Allen-Bradley 80026-524-01-R accepts a universal single-phase input of roughly 100-240 VAC at 47-63 Hz and delivers a regulated 56 VDC output at up to about 26.8 A. That 56 V rail is not a general-purpose control voltage; it is the DC bus that feeds downstream DC/DC converters and gate driver power supplies inside large AC drive architectures.
Inside a PowerFlex 7000 medium voltage drive, the Allen-Bradley 80026-524-01-R sits in the low-voltage compartment and forms the first conversion stage: single-phase mains is rectified and regulated to 56 VDC, which the DC/DC stage then distributes as the 5 V logic, ±15 V, 24 V and 20 V isolated gate driver rails the power structure needs. Rockwell documentation notes that where a Cosel unit is fitted the output is 57 VDC, while the Pioneer-pattern supply — this part family — produces 56 VDC, and that input and output voltages are monitored with fail signals annunciated when DC output falls below the preset threshold, typically around 49 VDC.
The same electrical specification also serves the legacy Pioneer DC motion control platform, where a 1.5 kW, 56 V supply provides the DC bus for servo drives in CNC machine tools, textile and packaging machinery. Positioned between the plant mains and the sensitive control electronics, the Allen-Bradley 80026-524-01-R is the component that determines whether a drive starts cleanly, rides through voltage dips, and shuts down in an orderly way rather than collapsing into a nuisance trip.

Main Features and Advantages
Purpose-built for medium voltage drive control power: The Allen-Bradley 80026-524-01-R is not a generic DIN-rail supply. It is engineered to the specific duty of feeding the DC/DC converter and the isolated gate driver power supply modules in a PowerFlex 7000, which means its 56 V output, its hold-up behaviour and its failure annunciation are all matched to what the drive’s power structure expects. When the DC output sags below the preset threshold, the DC FAIL signal transitions and the drive reports the condition rather than continuing to run on marginal gate power.
Wide-range input that tolerates real plant mains: Accepting roughly 95-265 VAC across 47-63 Hz, the Allen-Bradley 80026-524-01-R can be installed without voltage selector strapping, which removes a classic commissioning error and lets one part number serve machines destined for different national grids. Factory documentation for this class of supply also specifies input and output monitoring, so brownouts and sags are detected and annunciated instead of silently degrading control electronics.
High power density with active power factor: Delivering 1.5 kW from a single-phase feed at a power factor of about 0.98, the module reduces the current a control cabinet draws from the mains and reduces the heat that cabinet has to reject. Less waste heat means the surrounding drive electronics run cooler, which is the single biggest contributor to long capacitor and fan life in a drive’s low-voltage compartment.
