The Duracomm models I have are Meanwell on the inside, but in a more convenient 1U package with a power cord and rocker switch pre-wired. I have no complaints. It's probably the easiest thing.
I've also used these: https://www.antaira.com/products/din-rail/SDR-240-48?gclid=CjwKCAiArY2fBhB9E iwAWqHK6lPHG1X0bxqrg0RjjeXES8WuZWGklUFY2H5TSJrLtn86yDM2vxdsqBoCfrMQAvD_BwE I'd bolt a DIN rail to a 2U blank and mount it on the back side of a 2-post rack, but with DIN rail facing the front. You can fit I think 7 of them between the rack posts. It's a pretty compact way to hook up a whole bunch of devices on independent power supplies. 240W is probably overkill, but it'll power just about anything you'll have. We used them with -48V Trango, Telrad, and Ceragon gear. -----Original Message----- From: AF <af-boun...@af.afmug.com> On Behalf Of Mark - Myakka Technologies Sent: Wednesday, February 08, 2023 10:26 AM To: AnimalFarm Microwave Users Group <af@af.afmug.com> Subject: Re: [AFMUG] Neg 48V Power Supply Sterling, Check out duracomm.com.
