Hello all, I was doing my morning eBay check and came across these: http://cgi.ebay.com/AT-T-DC-DC-Power-Modules_W0QQitemZ7588490888 I need a constant voltage 130VDC so these aren't much use to me but they might be useful as a 60 mA current loop supply. I found a PDF of the spec sheets and can send them to anyone who wants to see it. PDW
