Many years ago when analogue modems ruled the world, I had a local
transformer company create a handful<br>
of transformers to take in 240v AC and put out 30x 20v AC to feed some
modem banks.<br>
<br>
Different for you, but for someone with some electronics knowledge I
wouldn't imagine it would be too hard to<br>
bring 48v down to 12v DC for a modem which ran on that... <br>

<p class="MsoNormal">I have an application for some dial-up modems
for out of
band management but the only power available is 48v DC. Does anyone
have
a line on any reasonably priced serial dial-up modems, or perhaps a
dc/dc
converter or what have you that would let them run off 48vDC? The ones
I’ve
found have all been industrial-strength hardened type stuff and
clocking in at
$700+ which is just not practical.<o:p></o:p></p>
