Hello, I'm working on a mains powered design and am having difficulties finding a wall plugin 'shell' to use for my design. I would like to place a custom PCB inside the wall plugin (picture a cell phone charger, and cut the cord) and have my circuit mains powered. My circuit will require around 300mA at 3.3VDC. Any suggestions? Would something like this have to go through UL certs if I find the ACtoDC converter in an enclosure that is already UL certified?
Thank you in advance!
