Applications
This supply was designed for vintage minicomputers, industrial control systems, and legacy telecom equipment requiring multiple voltage rails. It supports systems typical of the 1980s–1990s era that needed discrete positive and negative supplies for analog and digital circuits.
Please note: We may have multiple units of this item in stock. The unit you receive may vary slightly from the one shown in the photos. All units are functionally equivalent and inspected to the same standard.
This Microcomputer Power CP129 multi-rail DC power supply has been tested at our facility and is in good working order. The cooling fan operates normally; however, the plastic fan housing has a visible crack, as shown in the photos. The unit powers on, the indicator light is present, and all output rails were confirmed functional during testing. Cosmetically the unit shows typical age-related wear consistent with vintage equipment — the black enclosure has minor scuffing and the label remains legible. The output connector (J1), IEC power inlet, rocker power switch, and fuse holder are all intact and serviceable. Please view our photo set and contact us if you have any questions.
