Applications
This supply was used in NCR System 3000, System 8000, and related vintage minicomputer platforms from the 1970s–1980s. It provided stable multi-rail DC power to processor cards, memory modules, and I/O subsystems in mission-critical business computing environments.
Condition: Used
This NCR 530-0009297-1 mainframe power supply has been powered and tested at our facility and is in good working order. The zinc-plated steel chassis shows the iridescent patina and light surface wear typical of vintage industrial equipment of this era, consistent with prior deployment in a mainframe environment. The output wire harness with its multiple blade and ribbon connectors is intact and present. The rear-mounted Nidec cooling fan, AC input, and front-panel power control switches are all present. Fuse holders and voltage adjustment trim pots are intact as visible in the photos. Please view our photo set and contact us if you have any questions.
