The ultimate DIY benchtop powersupply

thingiverse

What's a great workshop without a rock-solid adjustable power supply? This system relies on a robust Dell EPS-470 server power supply, which powers a reliable DPS5015 adjustable power supply to deliver a 0-48v 0-10a supply - exactly 9.6a as the max output of the EPS-470. These high-quality EPS-470's can be found for under $50 on eBay, and the DPS5015 can be snagged for under $40 on AliExpress or eBay. For under $100, you can build a wicked reliable precise bench top supply that gets the job done. You can also use two DPS5005 units in parallel to create a dual voltage output system - the possibilities are endless! The case mounts snugly to the top of the server supply and is secured with 5x M3 or 4-40 standard style computer case screws. A bolt pattern DXF file is included for drilling the top power supply case for the enclosure - just be sure to update it with the bolt pattern for the DPS5015 daughter board. A picture is attached showing where to connect into the high-current 48v source. The plug can easily be unsoldered and your new wires soldered in place. Don't worry about that unused pin reading 46v on a DMM - it's some type of low-current switching/communication point, not the high-current 48v tie-in point.
