A local guy converts power supplies and the price is not too bad. He said his favorite is the DPS-800 because of its size, output and its quiet compared to DPS-600. My main concern is the PCB that extends past the case and the amount of exposed material. The part of the PCB for Pos/Neg looks to be about an inch. We have lots of metal tools on out tables and I pit with a 9 year old, so I have a little bit of a safety concern on the exposed parts. I could maybe use RTV to coat it and make it safer. Unsure if I could shrink wrap the end. Has anyone used this model? Any thoughts?
