Boy, was I ever confused. Seems my memory isn't as good as I would like to think. I got off my duff and actually looked this AM. I was confusing several displays.
What you are looking at is a Precision Control Systems item #10025-500.
Here is a link to the page that discusses it's workings and operations. You just push the select button to select which mode you want according to how much power is available and then it's all automatic.

Sorry for the confusion and misdirection.
