And you need to size it for both load current and charging current after an outage. Like double the load current or more.

If it is an AC site, that doesn't get a lot of power outages, running everything at the float voltage works pretty well. Just understand that there will be no bulk or absorption charge after an outage. bp <part15sbs{at}gmail{dot}com> On 5/25/2016 10:28 AM, Mathew Howard wrote: Yep, we just run everything at 27-28v, pretty much everything is happy that way.

If you're just looking for AC-DC, then the SDR-120-24 is fine with the adjustment pot cranked up to 29.5. In my environment though, since I try to keep everything on the same rail and use as few DC-DC converters as possible, say a MikroTik switch/router that takes a max of 28VDC, 29.5 is a bad idea. And probably not a good idea for an UBNT radio either, like a RocketM5 on a shorter run.

It's easy to find 24vdc but the 30vdc is elusive? I have been using the Meanwell SDR-24vdc and cranking them up to 28 vdc but I would rather do it right. Anyone have sources for such Power Supplies? thanks Sam -- -- Sam Lambie Taosnet Wireless Tech. 575-758-7598 Office www.Taosnet.com
