Also there is a fuse in the Traco BCM, I assume you’ve checked that. I have at least one of these and it works as you’d expect. I think George has a bunch of them, maybe he’ll weigh in.

I may just be missing them, but if not, you may want to consider adding some. It would be a good practice to put DC breakers/fuses in between your battery bank and charger as well.

I followed the instructions from Traco, but as you can see the battery is currently at about 23v and that is what the Traco power supply is outputting. The instructions say to turn the power supply all the way down and to let the BCM control the output. It's all set up, jumper is in position 1, the feedback cable is connected between the PS and the BCM but the BCM doesn't appear to be telling the power supply to do anything except turn on. Anyone with some experience with Traco care to tell me what I'm doing wrong. It's worked like this since day one, the BCM doesn't appear to be doing anything regardless of the battery voltage. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Christopher Tyler" <[email protected]> To: [email protected] Sent: Wednesday, April 8, 2015 3:19:35 PM Subject: Re: [AFMUG] Low Voltage Disconnect Commercial power. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Ken Hohhof" <[email protected]> To: [email protected] Sent: Wednesday, April 8, 2015 3:18:25 PM Subject: Re: [AFMUG] Low Voltage Disconnect Is this powered by solar or commercial power? One approach is to use a charger that includes a LVD, like the Traco TSP-BCM (which controls a TSP series AC/DC power supply). The LVD is fixed not adjustable. -----Original Message----- From: Christopher Tyler Sent: Wednesday, April 08, 2015 2:23 PM To: [email protected] Subject: Re: [AFMUG] Low Voltage Disconnect We are currently testing using two 12v 100Ah telecom batteries in series. They are slightly expensive to replace, especially when we will have four (or more) at some sites, most will have two. I'm using a Meanwell RSD-100B-24 regulator for the Tik RB-493G router right now. Looks like the cutout for the regulator is around 16v from what I can decipher from the datasheet. My test radios (2 Canopy and 2 UBNT) are connected to the battery without regulation. This setup will drain the batteries until they are pretty much dead and buried. I ran them over the weekend and I figured it would stop draining around 10v at worst, it didn't. They ended up around 6v in parallel or 3v per battery. I figure I shaved off some capacity and lifetime of my test batteries with that, hopefully not too much. -- Christopher Tyler MTCRE/MTCNA/MTCTCE/MTCWE Total Highspeed Internet Services 417.851.1107 ----- Original Message ----- From: "Josh Luthman" <[email protected]> To: [email protected] Sent: Wednesday, April 8, 2015 1:49:05 PM Subject: Re: [AFMUG] Low Voltage Disconnect First off I'd suggest getting enough batteries that you wouldn't need an LVD. Second, I'd rather see my batteries lose a bit of life and keep the site up then have everything go down saving my batteries. Tertiary/finally, what equipment do you have now? My regulator cuts off at 19v and still provides 24v. I figure the batteries are at 9.5v they're already suuuuper low.
