I don't have a bench supply. But I did find an expired computer psu last night, and extracted the small pcb with most of its input filtering, and when I get my cramping legs to take me out there, plus input a couple cups of caffeine, I'll put it incircuit for effects. But first call JT, he has a 3 amp for little enough. Someone mentioned that the real meanwell's covers have hex holes. This one has round holes. Sigh.
