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+. $20/ea.

Message me if you want a bulk purchase and I'll check for you to make sure I can fill it. If you want a large quantity we can work out a bulk discount.

I do also have a smaller number of different spec units - higher wattage (192W) and I think there are also a few with 24V output. Most are the 48V 144W model.

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 am prompt responding to email, usually within an hour or two. Next day response at worst if I'm slammed with work.

If the post is still up, they are still for sale.
