I am not familiar with the SNOM SIP paging amp, but have used one from 
Cyberdata that has a line input for “background music”.  It will then break 
into the music for paging.  Would that accomplish what you want?

For the 450M, they send you an unlock code for the SFP port when you buy the 
SFP.  After that you can use whatever SFP.

Re: [AFMUG] Solar Array Voc

[Ken Hohhof]

So you already have the fiber and 14AWG running up the tower?  And what kind of 
14AWG wire, is it in conduit, or something like SJ cord?

 

That’s a lot of power and a long cable.  I’m going to assume you have some sort 
of AC UPS or generator at the bottom, and are not feeding 48V from a DC battery 
backup?

 

If you are having to run new fiber up the tower, I think I’d run a new DC power 
cable at the same time.  Probably multiple conductor SJ cord or tray cable or 
something like that, all that copper is going to cost some money, but you have 
a tough problem, and presumably for that much AP horsepower the tower is 
generating a lot of revenue.  Even with multiple power pairs you probably want 
something like 10 AWG.

 

With multiple conductors, you could divide up the loads and feed over multiple 
power wires, so one bad radio doesn’t short out the whole thing.  I would also 
try to use 56V for the radios that can accept it, most 48V radios can because 
they are designed to be powered directly off battery voltage.  The extra 8 
volts would give you a little extra headroom for voltage drop in the wiring.  
Some 48V power supplies have a voltage adjustment that you can crank up.  I 
haven’t seen many AC/DC power supplies with a nominal 56V output.  But I think 
a lot of the Mean Well and Traco supplies can be adjusted.  I know the Traco 
TSP series can, because that’s how the BCM adjusts the voltage to charge the 
batteries.

Another way would be to rectify a higher DC voltage down below (150 volts 
anyone?), and put a charge controller up top to regulate it down to your 48 VDC 
nominal. You'd get the lower current you're looking for.

440W.

Round up to 10A@48VDC.

 

10A will drop 25V over that distance on 14GA wire, so.  Not doable with your 
existing wire.   Even 10AWG is borderline.

 

You're either going to have to run multiple wires, or run AC power up to the 
top.   

 

I'd probably just put a din rail 10A 48DC power supply up at the top.   Or 
something like a Meanwell HEP-480-48 which might be safer as far as 'bare wire 
hazard' goes.

Hey Forrest,

 

Can I hijack this and get some questions answered?

I would like to put four 450M’s on an existing site we have. 

500 ft up with 14 Guage DC and fiber running up it to a NEMA.

We currently push 48Volt supporting existing 450i gear that will stay up.

 

My space at the top is limited. I will have to use your small Sync Injector PRO 
to power the new 450Ms.

Can you recommend a power supply for the bottom to push DC up?

I have some concerns with the current wire guage supporting the new load plus 
the six existing 450i units that are staying.

 

Thoughts? Ideas?

Let me see if I can re-phrase my question:

 

I'm redesigning a voltage input circuit for one of the sitemonitor products - 
this is for voltage metering, not for powering the device.   One of the common 
questions I get asked is 'can I monitor my solar array voltage'.  Currently the 
answer is usually 'probably not, unless you are certain the Voc is below 60V, 
and that one side of the array is already grounded to common (often isn't for 
mppt controllers)'.   I'd rather be able to say something like 'sure, as long 
as the Voc isn't over X volts', where X is high enough that it contains a 
reasonable subset of the arrays out there.   I don't think supporting 150V 
arrays is in the cards (and yes, I know the tristar MMPT goes up to 150V), 
since that starts getting in the range where clearances get hard to do on the 
circuit board.

 

So I guess
