All depends on the current.

So what’s the Traco parts list for that?
I don’t do this stuff normally, so excited to get started and try it out.
If I’m pushing 48v up top to a roof, what’s the voltage drop?
I assume these DC units can somehow be tweaked so that output can accommodate
for voltage drop.
What size wire is everyone using typically for this, usually 30-100 ft max
length?
I’m assuming it’s something like 10 AWG? At 48v and 5A and 50’ is maybe 47.5v
at the end?
So I would push 49 or 50v just to be safe?

FWIW - we have lots of EdgePoint S16's that are powered by Traco BCM/TSP combos
@ ~54V with no issues.
I agree with others - your battery plant should be 48VDC.

Yeah, I’ll probably just use 48v battery array in series and float higher.
That particular device can do 48v, it just may shut down POE if it gets lower
than 48v.

Why not run your system at 54 volts? If the radio freaks out above 54, just
set it at 54 and you should be fine. Battery strings don’t exceed the float
voltage of the rectifier. If you are worried about it float at 53.75 volts.

Having a hard time figuring out the exact part/price for something like this.
Which Meanwell part would take 48v and make it 50v or 54v 5A?

That's weird to me. Any telecom equipment made for 48v I would have assumed
they intended it to be used with a rectifier, and consequently I would assume
it'd be ok up to at least 56v continuous; and maybe more like 60-70v for a
short duration. But yeah, DC-DC converter is the fix.

You need to use a DC-DC converter for sensitive equipment like that.
Meanwell has a good selection.

Apparently the UBNT EP-S16 freaks out if it goes above 54v.
Is there any way to assure it doesn’t float/charge above 54v, or maybe
even just 50v?

contact talley or tessco for a price, don't trust what you see on google,
it's like 50% less

all 48v systems for battery power will float at 54v, it's also
adjustable via the battery chemistry

Ok, cool.
So can the 7bc2 be adjusted slightly to output 50v instead of just
48v?
There will be some loss going 100’ or so, right?

12-54v is inefficient, if you want 200ah of battery use 4x50ah
batteries for a 48v string
ICT24048-7BC2 360W 54v AC-DC + LVD + Charger
ICT-TMP - Temp sensor for charge compensation if batt's outside
ICT-WMB - Wall mount bracket
SITE Monitor - Voltage monitoring
Or
Alternativly;
48v din mount PSU
48v 'dc ups' to charge batt's and provide LVD
OR
48v din 'dc ups' with integrated psu + lvd + charger (i.e. DIN-UPS
48-5 cheaper options available)

I’m trying to put a “box” system together for our house POP sites
and need help with the DIN stuff and UPS.
Can you guys give me an idea or example of the following?
I want to take standard AC 15A in from a breaker outside the box.
And using maybe one or two 12v 105AH AGM batteries, supply 50v 6A
up the side of the house.
I have never ordered DIN parts like this, guess I don’t have to use
DIN, but would be nice.
Having a problem finding a DC to DC converter that takes 12v and
upconverts to 50v 5-6A.
Is this the cost effective method? Something like this:
Monitoring Sitemonitor Base Unit II SMON Base II
1.00 $100.00
$100.00
UPS Monitor Sitemonitor Int MorningStar MeterBus SMON
MorningStar 1.00 $60.00 $60.00
UPS Charge MorningStar Sunsaver Dual
1.00 $165.00
$165.00
Battery AGM Deep Cycle 105AH NPP FT12-105AH
2.00 $225.00
$450.00
DIN Parts like DC fuse/breakers and trunk stuff
1.00 $100.00
$100.00
DC 12v to 50v 5A
1.00
$150.00 $150.00
