The install instructions for it also mention a battery test, but like the other BCM units there's minimal information on how the test operates. I asked Traco for more information on the test it does. Maybe it's the same process as the TLB-BC I mentioned earlier today, just not documented as such.
If that's the case, the BCMU seems like a slam dunk. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest Internet Exchange http://www.midwest-ix.com ----- Original Message ----- From: "Ken Hohhof" <[email protected]> To: [email protected] Sent: Saturday, May 9, 2015 4:22:22 PM Subject: Re: [AFMUG] Another DC Question Am I understanding that unit correctly? It has a step-up converter from the battery, so unlike the BCM-12/24/48, the output will always be regulated 24 or 48 volts, not battery voltage? Also that it only needs a 12V battery? And can work with any DC power supply since unlike the BCM it doesn’t control the power supply output voltage?

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
