Yep, bought 2 of the AD-155c. Couldn’t even drive an UBNT S16, 4 ePMPs and a single 320 series AP, on a 260ft. tower with 12 Gauge wire.
Replacing tomorrow with Traco gear.

And it's jumper selectable between 24 and 48 volts. There's an internal DC-DC converter to take the 12VDC battery up to your selected output. The charging is limited to 12W. I have a few with 30-40Ah of battery connected. Recharge time is usually 12-14 hours. I had a 95W site running on the 37Ah for almost 5 hours. It never went down. Again, read the fine print. It's limited to 240W continuous and 360W for 3.5 minutes. If it's in a not so temperature controlled cabinet, don't even try to put more than 200-225 watts of gear on it. I have a few sites running a couple ApexPlus radios (75W a piece x 2) and other misc stuff, 450APs and a couple ePMP PTPs. It's near the limit. The regular BCM is a different story. There doesn't appear to be any charge current limiting. I'm fairly sure I killed a TSP360. I hooked up a string of 20Ah batteries to a BCM48 and it was pulling 10-12 amps out of the power supply. I could smell it starting to cook. I gave up on it. I do only the BCMU360 and a Mean Well SDR-240-48 now. Really small cheap-o sites get Mean Well AD-155's. For anything over 200 watts, do yourself a favor now and look at real rectifier solutions from Alpha, Eltek, Emerson or the new ICT 1U shelf which looks pretty good. That's where I'm going for the sites that need more power and/or more run time. A good rectifier shelf will have no problem with 100+ Ah of batteries and proper maintenance of them, like equalization, etc. On 2/6/2017 3:53 PM, Josh Baird wrote: I was simply referring to the time necessary to actually charge the string of batteries.. in your case, it doesn't sound like that is an issue (and it's not in my environment most of the time either). I'm not sure if there are other problems with using a large string like that on the BCM - but maybe someone more knowledgeable like George or Ken can chime in?

We're not normally getting back to back power outages, so I don't really care how long the charge time is. How are we pushing it other than the recharge time?

If it did work (I guess it probably would), it would likely take weeks to charge a string of 4x100Ah batteries. You may want to take a look at Eltek/Emerson or the new ICT shelf that was recently announced on this list. The largest string we have on the BCMU is 4x33Ah, and I have even been told this is pushing it, especially with decent charge times.

Do you need 360W? The Mean Well SDR-240-48 is an alternative. That's what I'm using with the Traco BCMU360's. If you read the fine print, it's worthless to put 360W behind the BCMU. They're rated 240W continuous and 360W for 3.5 minutes. And the SDR-240 is ~$70 vs ~$270 for the TSP360. If you really need it, there's the SDR-480-48, which is only 1/2 the price of a TSP360.
