Hi We’ve been around this one before. The KS boxes are powered by a switcher brick inside the box. There’s not a lot of reason go super crazy on the DC input. It’s fully isolated from the case ground. Even leakage / stray grounds should not be an issue in this situation. I would not run it off of raw un-filtered rectifier output. Anything that’s at least got a filter capacitor in it should do fine.
