That sort of sounds like it might work. Half the current on each 24V
supply. I bet if one of them failed, the output would go to zero
because of the isolation.

+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 :)
