Well, here's a question...
If one of those dies in-line, will it fry my SAF POE? :)

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.

+24 to +48? or +24 to –48?
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.

I would not use the SD. Get an RSD instead.

This is from my parts list. 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.

Throw some part numbers out there :)
