Are you planning to build a parasitic version of the SyncBox Junior?

For those using the older products, the new injectors are drop in
replacements. Same Price, Same size, etc. They come out of the box
configured just like the old injectors - you even wire them up the
same, just ignoring the two new connections.
The only changes are that if you're needing a 320 or 430 injector
you'll need to rejumper them to work with the odd pinning of these
radios. And if you're wanting to use the dual power rail
functionality and/or a different pinning style, you'll need to
rejumper them as well.
Just think of them as an enhanced version of the old, not really a
different product.

The new little SyncBoxes look awesome!
So the old 10/100 SyncInjector is gone? Damn. Oh well, guess we
need to start using the new stuff anyway.

The pdu design will be ground specific. The solid state relay
design will be isolated so it doesn't matter.

Will the -48 PDU be strictly positive ground, or is it
floating?
I.E.: Could I stock the one PDU for either type of loads, or
would I have to have separate +V and -V PDU's?

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.
