Up for your consideration / auction is an Vintage Lambda Power supply, this was made under contract by Honeywell, LMF5-OVM-R AC-DC switching power supply. Please read this description and review and examine all the pictures before placing any bids on this item. I have had this power supply in my possession since 6-30-2000. I bought this for a project that I never did get around to doing. It has been inside of dry storage of an warehouse for the past 12 years, I have not used it. It is made in Saint Louis Missouri from the top information plate lettering of engraved/stamped printing that was done at the factory. This was also made under contract by Honeywell Contract # F09603-78-6-1129/0001 NSN 6130-01-056-9927, Manufacturer Code 94580, Part # 10061038-101 Spec. CPO4V1049, Part of 10050641-101. This power supply is in very nice condition. It has been lightly used, with only some scratch marks on the bottom from being moved around in it's storage days. There are a few scratches on the top left edge of the case from being handled and that is all of the marks on the other sides of this case that I could find. The voltage adjustment screw works and does limit how high the voltage goes as you adjust the screw. The back panel connection points/terminals are in nice shape with only some light dust, and are in great shape with all the connection points only showing light use. The only thing I could find wrong is that are a few areas on the front face where the paint has worn away and the metal is slightly exposed and you can see this in the photos of the front face. All the sides of the casing seems to be in great shape with some small marks , there is a few areas where the factory paint has come off and there are a small bit of surface rust on there areas, please see the photos.. All the ventilation holes on the top and bottom are all clear and clean and are not damaged in any way. There are no burn marks or heat damaged paint anywhere on this power supply. There are several sets of mounting holes on the front,side, and bottom of this power supply, made of course to mount it inside of a rack or other mounting equipment. This power supply is currently wired for 120 input Voltage operation. This power supply was tested and found to be in partially working or used for parts only condition. There is no way for me to test the Amps Output of this power supply, as I do not have the proper equipment, or set up, to do so. It does turn on and you can adjust the voltage output of the power supply by using the adjustment screw and lock nut on the front panel.
