The RSD-200B-48 will definitely work, but it’s not DIN rail. The TL 060-124 DC is DIN rail, and I don’t see why you couldn’t stack its output on top of your existing +24 to get +48. I haven’t actually done it though. The input/output isolation spec is 1500V so you wouldn’t be violating any specs. The wiring might confuse somebody working on the equipment later. I have used the TL 060-124 DC a bunch of places, like to get regulated 24V (for fussy devices) from battery 24V, or to down convert 48V to 24V. It’s useful in enough situations that you can stock a few and not feel it’s an odd item you will never use again.

Dumb question, if it’s +24 to +48, would it be kosher to use a 24V to 24V converter with isolated input/output and connect the negative output terminal to +24 so they are in series? Seems like this would improve efficiency and cut the power requirement in half, so that a 60W Traco should be adequate. http://www.alliedelec.com/images/products/datasheets/bm/Traco/70062693.pdf From: George Skorup (Cyber Broadcasting) via Af Sent: Friday, November 07, 2014 3:50 PM To: [email protected] Subject: Re: [AFMUG] dc-dc step up / power supply I would not use the SD.

More than you are asking for and about $80 but I bet you can look at others in that series to find a better fit. -Ty On Fri, Nov 7, 2014 at 3:35 PM, Josh Reynolds via Af <[email protected]> wrote: Need some part numbers for cheap 24VDC -> 48VDC ~72W din mount step-up/power supplies.
