Can the terminal block handle 12AWG wire? If one of the outputs
shorts, does that take the entire PDU offline, or is there internal
limiting with the 3A per port.

The main difference is that the tycon product is fixed function, so as
long as you can monitor exactly what you want with it, it will work
for you.  If you want a different set of i/o then you're SOL.
I also would caution anyone passing current through the tycon product
to be mindful that the terminal blocks they use may not be able to
handle what they specify as a maximum current on a continuous basis.Â
Typically those types of connectors are rated at 12 or 15A and they
say they can do 20A. I'm hopeful that they have bought special
connectors to handle 20A, but even if they didn't they should be able
to handle short periods of 20A.Â
The packetflux Base 3 has evolved quite a bit from the early days,
although there are still some limitations due to us wanting the
current version to be drop in compatible with the previous version.Â
 But some of the updates make this more useful at a wisp DC site.Â
 For instance, the base 3 and most of the power distribution or
injection models will handle both positive and negative power, at a
much wider range than most units. So you can use both +24V and -48V
to power it up at the same time.Â

Nice. Good price too. What does Forrest have that is similar?

really wanted to say "Power to Telrad Compact 1000 - 270
azimuth". I think
they were talking about fixing that in a future version of the
base unit,
but I haven't used any packetflux lately so I don't know if
that's still an
issue or not. If you're powering 100W radios then you'd be
limited to 3 per
PDU. A fourth radio would put you over the 8A total. That
wasn't an issue
in my deployment, but if you're planning 4+ sectors per tower
then that's
something to be aware of. Next problem is wire gauge.Â
Anything bigger than
14ga is gonna have trouble squeezing into the connector on the
packet flux
PDU. Voltage drop on 48V /8A with 14ga is going to be pretty
severe at
300ft, but if the tower is short then it's probably ok. I
was deploying on
70ft poles, and we ran 16ga up to each radio so it was
acceptable, but
feeding the 8A input on the packetflux PDU on a taller site
could be an
issue.
In any case I'd advise separate cables. I know it seems
wasteful, but you
can have any tower dude climb up there and put the green plug
into the green
hole. If you want the tower climber to strip and terminate
DC cables then
you'd have to be careful who you send up there. If you're
dead set on a
single power run then something with built in breakers is a
good idea.
Packetflux PDU would fit that bill.Â

Subject: [AFMUG] Outdoor DC Distribution
Mikrotik makes a nice outdoor fiber switch with a handfull of
10G ports.
Does anyone make something similar for DC Distribution? Run
a single power
cable up a tower and DC to multiple radios? I'm thinking
like 3 or 4
licensed radios each needing 2 wire DC input and 10G fiber.Â
Rather than running individual power wires for each one.Â
I've used a UBNT
Edgepoint S16, taking the 56v POE Output ports, and running
them through the
MCT GIGE-POE to extract 2wire power to run to the radio.Â
But that's extra pieces needing a place to be mounted.
Would the Site Monitor 5 channel PDU fit the bill? IT says
3A per channel,
and 8A total. So in theory that should be able to provide
about 140w per
radio. Could put it in some sort of NEMA with a DIN mount.Â
The Sitemonitor
base is hardened, would the PDU be as well?
Are there other options?
