Up for your consideration / auction is an Vintage used Nemic-Lambda Power supply SR660-5 AC-DC. 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 12-31-2000. 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 11 years, I have not used it. It is made in Japan from the front lettering of silk screen printing that was done at the factory. This power supply is in very nice condition. It has been very 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. There is also some glue residue that is embedded into the paint on the middle left side of this top cover. The front panel is in magnificent shape with all the screw on terminals present and the Phillip-head screws are all in great shape with no rounding out of the heads of the screws. The two connection terminals are also in good shape and the tightening down nuts and washer are present and not rounded off. The flat surfaces of the nuts do show some ware but can easily be used or replaced as you desire. The power on indicator is present and looks to be in good shape. The V.ADJ adjustment screw is present and is not rounded out. The PJ1 connector numbered from 1 to 11 is present and looks to be in great shape with no marks on it, all the pin connections are present and straight and seem to be in great shape. The only thing I could find wrong is that a tab around the Left Connection block labeled AGC has a small corner of it missing. All the sides of the casing seems to be in great shape with no marks, except as noted above. The rear of the case has a fan installed in it and it looks to have been used lightly as there there is only a slight amount of dust deposited on the fins of the fan and inside of the intake cone of it. The connector going to the backside of the fan is in good shape showing no exposed wires and the connector is present and is properly plugged into it's connector. All the ventilation holes on the front side and top are all clear and clean and are not damaged in any way. There are no burn marks or peeling paint anywhere on this power supply. There are several sets of tapped screw in mounting holes on the side and bottom of this power supply, made of course to mount it inside of a rack or other mounting device. I tested the voltage out of this power supply and it seems to be working. I am unable to fully test the current output of this power supply, as I do not have a correct way to load test it. Since I can not fully test this power supply I will be listing this as partially working, or for parts only.
