Finally found a small, silent, 84v supply. ( In the past I’d had to get them custom made as a sample and they won’t sell them again). I had to buy five as you can see, which I don’t need, so selling them for $5 more than my costs.
Message me.
In my looking meanwell has a gap in what voltage stuff they sell and finding a 20s small silent charger … I’ve spent hours looking and had just put an ad on freelancer to get it made
