Umm....

??? 144W per channel @ 100W
It is limited to 8A (384W@48V) total across all outputs. This limit is
related to the maximum each pin can handle, and since this is arranged
with a single input and multiple outputs you're limited to 8A. But if
you need 100W just think of it as a 3 port PDU with a couple spare
low-current channels.
I mentioned in another thread that we have plans to make a version of
this to try to help where you're switching a lot of heavy loads. That
version will likely look like six solid state, programmable current
limited relays. More wiring, but more power since you can do 8A per
connector pin (so it might be as high as 8A per channel, but we need to
do thermal engineering before I can guarantee that). Oh, and removal
of the negative ground/positive power requirement is part of this.

This need might be less common in the wisposphere, but it would be
useful to me to have a relay or pdu module that could switch 100W
48VDC loads.

I have a preference for a switch that works.
My challenge has always been to find a chipset I trust which is
fairly easy to integrate, is obtainable, and is available in
industrial temperature range. Over the years I've looked at
numerous chipsets and have never found any that I would feel
comfortable to provide to my customers.
The industrial temperature range issue was probably the biggest one
since the vast majority of chipsets are only available in commercial
range and I refuse to ship a product which contains chipset only
rated down to freezing (there's a reason why we've never had any
temperature related failures that we can recall). Of the remaining
chipsets, many of the manufacturers only sell to large-volume
consumers. They have no interest in doing business with an
organization which doesn't do a million units of a product.
Well the never part was true until recently. A trusted vendor of
mine recently released a switch chipset with 5 Gigabit copper ports,
1 GBIC port, and 1 management port, and which seems to be able to be
integrated well. I need to spend some time with the eval board
which is sitting here, but other things have taken priority.
Over the last couple of months, we've pretty much finished all of the
pending projects, and so I'm working on figuring out which of the
partially started projects around here I need to pick up and run
with. There are some which are minimal work which will likely get
done soon (i.e. producing medusa-compatible cambium sync products in
various other form factors, and finishing a couple of i/o board which
are basically done).
Of the rest, part of what I'm going to be listening to at WISPAMERICA
is what people are needing. I really don't want to build things
people don't want, so I'm going to be listening as to what people are
looking for. I've got lots of ideas, just not sure how many of them
are really of interest.

Forrest,
It would be awesome if you could ever develop products with switches
inside, I know you have a (Cisco?) preference but other's dont.
I would have purchased lots. I hate that I have to use a separate
switch so we moved away from packetflux for new deployments.

I'm assuming you mean includes switch+poe.
I'm in the process of working on something specificaly for the
450i/450m with 5 ports and sync hardware all in one box (+1 SFP
port), mainly designed for tower top mounting. Not far enough
along to say when it will ship, or even if it's ever going to see
the light of day.
Any other solution you look at, you should make sure that whatever
solution you find will support at least 70W per port, and all 4
pairs. Neither the 450i or 450m really care about polarity, unless
you're doing sync, and then only on the 450i since the 450m does
the new cambium sync only.
If you can live with separate poe box, of course the packetflux
powerinjector+sync powers 450m's really well. There will be a
version which does medusa sync out sometime soon, it's a sure
thing, just we don't know timing yet.

Good morning,
Looking for an all in one, but reliable, power source for 4 - 450m
aps per tower.
I have heard netonix a few times but I have also heard about some
issues with these devices and their support not being that great.
