I asked Forrest about doing a -48 version of the 5ch PDU. He said it
would need some tweaking since the PDU itself is powered by the main
input, kinda like a SyncInjector.
Depending on your current, you could use a regular 4-relay exp. module
to switch the hot wire for each device. Should be able to handle about
1A @ 48VDC. Next question is, would a -48 version of the PDU support say
1.5A per port? I know you can set the per port limit to 3000mA, but I'm
not sure if it'd be capable of that between 44 and 58VDC. I want to say
I remember him saying 1.5A should be OK.
I have some Trango licensed radios that I'd like to get on remote power
control, but so far there's nothing to handle them. Nothing that I like
anyway. And the problem there is the damn 75-80 watts of power they use.

Is there a relatively cheap device that can take 48v in and switch a

I'm thinking like $100-200 kind of cheap. Small and DIN mount would
be best.
The packetflux PDU has a negative ground, so that's already out.
