Hey y'all, I'm in the process of building a VSPS and drew myself up a PCB for the power supply unit that I'm going to build. Fab from JLCPCB comes in units of 5, so I'll have 4 leftover. Willing to send them to anyone interested within the US for just the cost of shipping (<$10 thru USPS) 🙂 Just post here or send me a message if you're interested.
Here's the schematic and board layout; it's quite simple, just a fuse, switch, 120-12V dual-primary, dual-secondary transformer, and dual bridge rectifiers made up of individual diodes (in the same manner as RJM's DBRD board):
Board is 83x85 mm, designed to be installed in one of these enclosures off Amazon, though it has screw holes that you can use to mount it pretty much wherever you like: https://www.amazon.com/gp/product/B07HBWLZDQ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
Here's the necessary bill of materials to complete the build... you'll definitely want the same transformer (FP24-250) and fuse clips, but you can choose your own diodes, fuse, input/output terminals, and switch if you want
