Applications
This adapter was manufactured by IBM Japan for use with the IBM Communication Box (48G9840), an external communications peripheral designed for IBM personal computers and workstations of the early-to-mid 1990s. IBM Communication Boxes of this era provided serial and asynchronous communications capabilities — often used in Japanese-market IBM PS/2 and compatible systems for modem or network interface functions. The universal input range (100–240V) reflects IBM's practice of producing region-flexible power adapters for its Japanese and international product lines. Units like this are sought today for legacy IBM system maintenance and restoration, particularly by users maintaining original IBM Japan hardware that requires the 15V output and 5-pin DIN interface.
This IBM 48G8291 AC Adapter (P/N 48G8290) has been inspected and is in good used condition. The unit is clean and shows only light handling wear consistent with normal use. The label on the back is fully legible, the IEC C14 inlet and 5-pin DIN output connector are intact, and the included AC power cord is present. Please view our photo set and contact us if you have any questions. 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.
