List price on the BCMU360 is about $215 IIRC. I think we pay about $175 from 
PSUI. Plus $15 for the temp probe. 

Are you asking run time? I have a couple with 40Ah of battery attached. A few 
with about 90W load have ran for over four hours, but they never went down, 
utility came back. A couple others with ~190-220W. Lost utility at one of the 
sites the other day. It was running for about an hour and a half before I 
brought a portable gen out. That site didn't go down either. Couldn't let it, 
too much traffic. And of course utility came back 15 minutes after I got the 
generator going.

We have never used a Rectifier Shelf.  Is it an all in one solution, AC in DC 
out power for equipment and integrated battery charging?

720W site?   That’s some serious power.   At that point it’s time for a real 
rectifier shelf - call these guys:  

 

http://telecomsurplus.net/power/rectifiers/

 

They have a pretty good collection of Eltek rectifiers that would handle that

Depends on money.  If you have plenty of money I try for many days of autonomy 
on batts.  How many days to you expect to be out of power and then double it.  
If you have enough batts, you don’t even need the genset.  

If you are scrimping, a genset with a few batts is the best value for providing 
backup energy.

List price on the BCMU360 is about $215 IIRC. I think we pay about 
$175 from PSUI. Plus $15 for the temp probe.


Are you asking run time? I have a couple with 40Ah of battery 
attached. A few with about 90W load have ran for over four hours, but 
they never went down, utility came back. A couple others with 
~190-220W. Lost utility at one of the sites the other day. It was 
running for about an hour and a half before I brought a portable gen 
out. That site didn't go down either. Couldn't let it, too much 
traffic. And of course utility came back 15 minutes after I got the 
generator going.

720W site?   That’s some serious power.   At that point it’s time for a real 
rectifier shelf - call these guys:  

http://telecomsurplus.net/power/rectifiers/ 
<http://telecomsurplus.net/power/rectifiers/>

They have a pretty good collection of Eltek rectifiers that would handle that 
load nicely.

Well, that is a concern. I think we'll be under 30A after all is said and done 
and the DR-UPS40 handles 40A. Downside would be the 2A charging rate. I should 
note this site will have an automatic standby generator so we won't need a huge

The Meanwell SDR-480P-24 and -48 do current sharing so you can stack up to 8 of 
those in parallel to have a lot of capacity and N+1 redundancy without the 
DR-RDN20 redundancy module.

We're getting ready to do a four unit N+1 at a site that has 16-17 Amps already

The Meanwell SDR-480P-24 and -48 do current sharing so you can stack up to 8 of 
those in parallel to have a lot of capacity and N+1 redundancy without the 
DR-RDN20 redundancy module.

We're getting ready to do a four unit N+1 at a site that has 16-17 Amps already 
and is getting some LTE base stations added to it.

List price on the BCMU360 is about $215 IIRC. I think we pay about $175 from 
PSUI. Plus $15 for the temp probe.

Are you asking run time? I have a couple with 40Ah of battery attached. A few 
with about 90W load have ran for over four hours, but they never went down, 
utility came back. A couple others with ~190-220W. Lost utility at one of the 
sites the other day. It was running for about an hour and a half before I 
brought a portable gen out. That site didn't go down either. Couldn't let it, 
too much traffic. And of course utility came back 15 minutes after I got the 
generator going.

All this stuff is fine until you start looking to deploy things that are 
power hungry like 450m's @ 70W, LTE eNB's that pull 60-100W each, 
multiple AF24s or licensed radios, etc. Then you need big-boy 
rectifiers, which aren't all that expensive, but they aren't cheap 
either. Add good telco-grade batteries on top and it's easily 10x the 
cost of what we're used to with the smaller stuff.

I normally have our other guy take care of that part.  But we normally
have a DIN mount 24V power supply, a DIN mount packetflux site monitor
that monitors power supply output and battery voltage and some DIN
mount module that does charging and switching between the two.  Also
have a 24V to 48V converter to power our 450i etc stuff.

Monitor the site monitor with SNMP and start emailing alarms if power
supply voltage drops.  Also graph power supply and battery voltage
with MRTG.

Re: [AFMUG] 24V Battery Revert and Charge Module

2017-05-20 Thread Bill Prince 
If you are using a DC UPS, there is no switching required on your part. 
The load, batteries and AC line in are all separate from each other. If 
AC line voltage is active, power comes from there. If AC line voltage is 
not active, then power comes from the batteries. If the controller has 
LVD, it will maintain until the batteries get to the LVD. If it doesn't 
have LVD, then the controller  will maintain until the batteries are 
depleted.


If you are just using a smart charger, you hook the load directly to the 
batteries, and hang tough. No switching required here either.

Re: [AFMUG] 24V Battery Revert and Charge Module

2017-05-20 Thread Chuck McCown 
Not totally sure what you are asking here.  Normally there is no switching. 
Everything is running the DC bus.  When AC fails the rectifier/power supply 
just stops supplying DC power to the bus.  So the batts supply the current. 
Power comes back on and the rectifier once again powers the loads and 
charges the batts.
