- Power supply, 12V-18V DC, >=20W.
I think it's easier to find a PSU with a standard round DC connector, like this one and thus we need a converter cable to our Molex power connector. http://domino2.kycon.com/catalog_PDF/KLDX_SMT2.pdf
Not knowing center pin polarity or exact center pin size, it seems as though digikey (http://www.digikey.com/product-search/en/power-supplies-external-internal-of...) has 348 that are 12-18v output, 10-20w, and have connectors that are 2.1mm ID to 2.5mm ID
I haven't realized that DigiKey, Avnet and others have PSU section, thanks!
Anytime =)
On a side note, for power -Something that could come in useful since its got ethernet, PoE?
PoE is an option, but UmTRX require too much power for the standard PoE and we think that for lab usage PoE is an overkill.
Whats the total power budget? 802.3AF should be kosher with 13w at the device, 802.3AT (PoE+) should be good up to a little over 20w
Im with you on the lab piece, Im just thinking of a seemingly ubiquitous power source in a industrial environment -I bring this up since so many industrial Wifi AP's (Gateworks, JJPlus, etc.) are PoE powered
- Enclosure. We'd love to have a nice table-top enclosure for UmTRX,
but it requires a significant effort to source, design and assemble.
If anyone has some preexisting case designs, there's always protocase (protocase.com) or Rapid sheet metal (http://www.rapidsheetmetal.com/parts/enclosures.aspx) -Im sure theres plenty of other sheetmetal fabshops that will do custom work though, If youre wanting to use something a bit more generic -Theres enclosurehub.com
Interesting. Do you know similar ones in Europe? We manufacture in France and shipping enclosures from US doesn't look like a good idea.
Not that Im aware of, I know of protocase since they did the backblaze storage pods & you can order anything from them in individual piece quantities -But thats not to say that there arent plenty of others that offer the same services, I would imagine there would be a fair amount of places in europe that will do sheet metal enclosures -If you want something extruded though, they might have a MoQ to make the cost of the die fabrication feasible...?
