Description
Power-One F24-12-A DC Power Supply 24VDC 12A 28VDC 10A 115/230VAC For Parts
The Power-One F24-12-A is a linear DC power supply from Power-One's International Series, designed for universal AC input and selectable DC output voltage. It is a chassis-mount, open-frame unit built around a large mains transformer, Sprague Powerlytic filter capacitors, and a regulation PCB — typical of the robust linear supply architecture Power-One produced for industrial and instrumentation applications. This unit is being sold AS-IS for parts or repair and is not functional at rated specification.

Applications
Power-One's International Series linear DC power supplies were widely used in industrial equipment, instrumentation, telecommunications, and OEM machinery from the 1970s through the 1990s. The F24-12-A's jumper-selectable input voltage range made it suitable for deployment in both North American (120V) and international (220–240V) environments without hardware changes. Units like this provided stable, low-noise DC rails for sensitive analog circuitry, industrial controls, and embedded systems — applications where the low ripple of a linear design was preferred over switching supplies. Power-One was a well-regarded American manufacturer of linear and switching power supplies for OEM and industrial markets, and their chassis-mount open-frame units were frequently integrated into custom equipment enclosures and rack systems. Repair technicians, hobbyists, and parts salvagers seek out these units for their high-quality transformers, large-value filter capacitors (such as the Sprague Powerlytic units visible inside), and discrete regulation circuitry, all of which retain value for repair or repurposing.
This Power-One F24-12-A International Series DC Power Supply is being sold AS-IS for parts or repair. During testing, we found that these units output an average of approximately 18 VDC — significantly below the rated 24 VDC or 28 VDC specifications. They are not meeting rated output and are not suitable for use as functional power supplies without repair. They are offered at parts/repair value only. 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.
