Hi Mike. How are you? Yes we do for VL, not BNETB. It is based on the BS-SH chassis. You would order a BS-PS-VL-48 and the appropriate chassis radios. I do not have a -48vdc stand-alone supply though. Just the one I mentioned earlier.

Eric, Does Alvarion have a -48 DC supply for BreezeNET B and VL?

FYI... Alvarion is shipping a DC power supply that supports all of the VL and BreezeNET B radios. The part number is 858554 and model number is the OPS-DC. It accepts 12-28VDC at 7A max and outputs 55VDC at 1A. It might help all of the brave souls that work off the grid.

FYI we had a 11-28vDC input to 48vDC output unit made for the wind/solar power design: http://www.demarctech.com/store/catalog/product_info.php/cPath/21_34/product s_id/247 While there is some energy loss in the conversion the overall cost and quality of a 12vDC works out better than using a pure 48vDC when you consider one could use this design to power other non-48vDC systems.

I think Paul Gipe is a respected name in wind. I was looking at his site over the weekend, he has an older review of the Air-X, he seemed to think it should really be rated as a 200 watt generator. http://www.wind-works.org/articles/sm_AirXtest.html (I see the company has a newer model out now called the Air Breeze, rated at 200watts) He also links to another test site: http://www.detronics.net/ airx_report.pdf They have another report that lists the advantages of running a combination of wind+solar to balance things out over the year. But I think this is highly variable, depending on an area's sunshine and windspeed. ------ Lucaya has complicated things for me by requiring 48V on their new radios. (I was just going to run radios directly off 24V batteries) Does anyone know about the Powerstream PST-DC2448 (converts DC 24 -> 48V) http://www.powerstream.com/dc12-48.htm Or suggestions on other reasonable ways to keep radios running for several days of no power? All my sites have grid power so far, I've decided that my best investment is in batteries.
