12V to 48V 144W DC-DC Step-Up Boost Converter Voltage Regulator IP67 Waterproof

Description: Acquired as part of multiple lots in a custom commercial vehicle upfitter liquidation auction, I have a large quantity of 12V to 48V DC to DC converters. I have not yet counted all of them but I'd estimate I have 100+. Listing 10 to start, I'll increase the number available only as I confirm the model number on each one. Message me if you want a bulk purchase and I'll check for you to make sure I can fill it. If, at the time you see this listing it shows I have 30 or 100 or however many available, that means I have confirmed I have at least that many of this exact model on-hand. If you want to buy 10 or more, message me and I'll make a lot listing for you at $20/ea. Wemaxpower brand, model WMX-DSD12S4803. Max output current 3A, max output wattage is 144W. They have a cast aluminum shell that functions as a heat-sink and are quite thoroughly potted and sealed. The input and output wires are solder-tinned pigtails and are around 7 inches in length with minor variance. Input wires are heavier gauge than the output (which makes sense as they will have the higher current load). I hooked one up to my bench power supply and load-tested it as high as my bench supply would go for output current, it works as advertised. See pictures for demonstrated output testing under load. Regulator output is quite good, when I was drawing 0.7A my DC load was registering 47.99V. I wasn't able to show the full 3 amp draw due to output limitations on my bench power supply. I do have an old 1980's Hewlett Packard boat anchor of a power supply that would do it no problem, but I haven't wired it into my bench yet. BE AWARE: you'll see plenty of these available and many will claim 'US Seller'... yeah.. I've bought parts from those kinds of listings before and afterwards found out they shipped from China and used a package forwarding service so they could give a US-origin tracking number. Deceptive practice. I waited 4 weeks for what I ordered. I'm not a drop-shipper. I have all of these in my possession at my home in Michigan. You will not spend a month waiting when ordering from me. Orders placed Sunday through Thursday will ship next day. Orders placed on Friday or Saturday may not ship until Monday.
