The only negative voltage I have ever ran into in telecom has been the –48 VDC. Of course you used to have +/- 15 for RS-232. Some –5 on the old PC power supplies, no idea where it was used. I have never seen any other negative voltage used outside the chassis of equipment. Telecom originally

I'm looking at a 48V Meanwell RSD with an input range of 33.6 - 62.4V. Seems strangely specific. -- Original Message -- From: "Robert Andrews" <i...@avantwireless.com> To: af@afmug.com Sent: 11/9/2017 2:32:44 PM Subject: Re: [AFMUG] Negative Voltages... -62 for Batt

It should support something like -42 to -60. The topside is normally something like -56 but -60 gives a little margin. On Thu, Nov 9, 2017 at 2:09 PM, Adam Moffett wrote: > I don't recall ever seeing anything other than -48. Personally if you > accept the range from "dead

Re: [AFMUG] Negative Voltages...

I don't recall ever seeing anything other than -48. Personally if you accept the range from "dead battery" to "fast charging battery", and do something non-destructive when voltage is out of range, then I'll be happy as a clam. -- Original Message -- From: "Forrest Christian (List
