That's cool! I can wait for the new stuff. And I'll mention that I'm
much more interested in the devices with electronic over-current
protection to eliminate fuses.

I have around 10 or so new/revised products which will be shipping
over the next few months. (4 of the ones in our backlog have just
started shipping the last couple of weeks, and others are coming off
the pipeline shortly).
At least two of the coming products are intended to fix the lack of
-48VDC support. One of which is the addition of a 5PDU for -48VDC
(which is able to be powered from the -48VDC power source so it
doesn't need a base unit). The other one I can think of right now is
there's a 6 channel solid state relay coming as well. Both will
switch -48VDC at at least 3A. The PDU has a maximum-all-channels
limit of I think 8A. The SSR module will not have this limit.
I can build a -48VDC PDU on the existing board: To date I have not
had any customers ask me to do so once I have explained that this
module would have to be connected to a base unit, and rebooting or
losing the power to the base unit would result in all of the -48VDC
loads attached to the PDU being shut off during the power loss or
reboot. This is also the reason it is not currently on the website
as an option.

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 handful of -48vdc loads on and off?
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.
