Most of the time we either do a 24v power supply and batteries plus a 24v
to 48v DC-DC converter, or a 48v power supply and batteries, with a 48v to
24v DC-DC converter (mainly depending on whether there's more stuff that
needs 24v or 48v), but sometimes we'll do completely separate 24v and 48v
We down-convert 48V to 24V when necessary (using Traco DC-DC converters),
but that is few and far between these days since old school UBNT and FSK is
mostly a thing of the past.

For you guys that are utilizing these, do you normally do a 48V and a 24V
volt power supply for mixed sites? Or do you do what I think I saw Ken
mentioned before - 48 to 24V converter for the few devices that may require
24v?

The NDR series appears to do self recovery too... the only difference I can

I went with Meanwell SDR for most stuff. I think the thing that sold me
was self recovery from fault conditions.
A lot of power supplies detect a fault and shut off, but then you have
to unplug and plug them back in to recover.
Anyone routinely using a reboot switch to "fix" problems might
