I had thrown this out to FB earlier:
Thoughts the different systems. These would be for smaller sites. Bigger sites would likely get a 48v plant, 4x 100 aH batteries, etc. 1 === Traco TSP090-124 Traco BCM24 2x 12v 22 aH batteries First idea Electronics roughly same cost as #2, but larger capacity 2 === Traco TBL060-124BC 1x 12v 22aH battery Repeater site Electronics roughly same cost as #1, but has a battery testing system, could add second battery to match uptime 3 === Traco TSP090-124 Traco TSP-BCMU360 2x 12v 22 aH batteries Mostly costly option (by about $50), but could upgrade to full site without changing out BCM, can accommodate two power supplies for redundancy. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "George Skorup (Cyber Broadcasting)" <geo...@cbcast.com> To: af@afmug.com Sent: Saturday, May 9, 2015 4:03:15 PM Subject: Re: [AFMUG] Another DC Question This is where the BCMU-360 makes sense, 24 or 48v in one unit.

My reaction is 60W is kind of low, plus I can use 3 different sizes of TSP from 90 to 360W with the same BCM or alone as just a power supply or add the BCM later. And if it fails, I only have to replace the failed unit. And if the BCM fails, the site can run on just the TSP if I don’t have a spare. And there is a 48V version of the BCM. So it seems more flexible. From: Mike Hammett Sent: Saturday, May 09, 2015 12:22 PM To: Animal Farm Subject: [AFMUG] Another DC Question Has anyone looked at the Traco TBL-BC before? It seems to do a lot things other than basic battery charging and even temperature compensation. It's not all that big, but may be good for repeater sites. Seems to be about the same cost for a bigger power supply and regular BCM as this guy, but the alternative wouldn't have the battery testing system. http://www.powergatellc.com/pdfs/TBL-BC.pdf ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com
