Applications
Terminal base power supplies supported IBM's early display terminal products used in business computing environments from the 1980s onward. The 3178C and 5291-2 were monochrome display terminals deployed in mainframe-connected workstations. This supply converts AC mains to regulated DC outputs required by the terminal's display and control circuits.
Condition: For Parts or Not Working
This IBM 5641249 EC865172 Terminal Base Power Supply has been visually inspected and powers on — the green status LED illuminates when connected. However, we are unable to fully verify all DC output rails or perform a complete functional test of this power supply, and it is therefore being offered in a used, untested condition. The unit appears cosmetically sound with the typical brass-toned iridescent patina common to open-frame PSUs of this era; the heatsink, ventilation cover, and connectors all appear intact with no obvious physical damage. Please review our photo set carefully and contact us with any questions before purchasing. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function. Visit Our Store
