Description
Power-One F24-12 DC Power Supply 24VDC 12A 28VDC 10A 115/230VAC For Parts
The Power-One F24-12 is a linear DC power supply manufactured by Power-One of Camarillo, California. It is a dual-output-voltage, open-frame linear supply configurable via internal jumpers for either 24 VDC at 12 amps or 28 VDC at 10 amps, with a wide-range AC input that accepts frequencies from 47 to 440 Hz — making it suitable for both 50 Hz and 60 Hz mains and even aircraft power systems. This unit is being sold strictly as-is for parts or repair.

Applications
Power-One's F-series linear DC power supplies were widely used from the 1970s through the 1990s in industrial control systems, laboratory instruments, telecommunications equipment, and embedded electronics that required a stable, regulated DC rail. The F24-12's wide input frequency range (47–440 Hz) made it a common choice in applications where power quality was variable or where military/aerospace-adjacent equipment operated on non-standard frequency sources. Linear supplies like this one were preferred over switching supplies in noise-sensitive environments because they produce far less high-frequency ripple. Today, F-series units are sought by engineers repairing vintage industrial and lab equipment that originally specified this supply, as well as by hobbyists and electronics technicians who use them for repair, bench experimentation, or as a source of components such as toroidal transformers, large-value filter capacitors, and linear regulator modules.
This Power-One F24-12 DC Power Supply is being sold as-is for parts or repair. During random testing at our facility, units from this lot were found to output an average of approximately 18V DC rather than the rated 24V or 28V DC. As a result, these are not suitable for use as-is and are listed strictly for parts or repair purposes. Notably, the transformer in the photographed unit shows visible heat damage to its winding/insulation, which may account for the under-voltage output. Please review our full photo set carefully before purchasing 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.
