Hi Mark, I bought the HE versions there are also SHE (Super High efficiency) units available but they are a bit dearer. The main difference is peak efficiency of 96% versus 97.8%. Here are the Datasheets to save people searching

Im quite happy for the brand new 96% units @ $100. I brought them from an ebay supplier here who said he can get more, although currently he does not show any of these for sale - it would be worth an email to him. I was so tempted to buy his remaining 5 when I saw them but didnt want to incur any wrath from SWMBO.

Their output voltages for the HE & SHE are both 43.5 to 57.6V adjustable with a controller - the ebay seller pre-sets them to 48V before shipment. If you google VK4ghz there is a project for a controller for these units using their canbus. I'm in the process of building one up. They are essentially built for battery charging and there is software available & prebuilt Eltek controllers to manage them off the shelf.

They should work fine from a generator and can supply output all the way from 85 - 300 VAC / 85 - 275 VDC, but at reduced power below ~ 185VAC.
