Thanks. I just bought one of these from a store that had taken it in on a trade but there was no manual and they did not know which version it was. Based on your description of the 3 versions, it sounds like it is the "B" model.
What seems odd is that unlike the original Power Block (which I have had for 20 years) these units do not regulate voltage. They seem to be more of a power conditioner type device.
I will update after I install the PB III.
