Hi, I'm after a robust 50VDC power supply with floating output, and wondered whether an 'old' telephone system PSU might do. What sort of supplies are used to source the 50V system, will they deliver clean DC without a battery bank? Is there a disposal source of them anywhere? TIA
Why not a SMPS?
Look at the Meanwell SMPS, prices are reasonable. Eg NES-15-48 A$14.60ea. You'll have to trawl through and check for floating output & other specs etc. They are good to deal with. (No relationship with them, just a past customer)
