I ran into this looking for something else on ebay:
Digital Constant Voltage Conditioner H7225 item 331591861028
I don't think I ever saw one of these before, were they of any use?
I have one. Heavy beast. It is a ferro-resonant transformer that is
roughly equivalent to what folks may know as a "Sola" (now owned
by Emerson) or other sort of line voltage stabilizer.
Mine is model 7225-AA and is only rated at 4A @ 120VAC and for the weight,
seems like I'm getting jipped.
I don't know what DEC's intended use was for them but I have used mine
at ham radio antenna range testing and other outdoor venues where the
AC power comes from a generator or over a very long extension cord and
have powered small amounts of test equipment or radio gear from it.
It takes a wider range AC input and "regulates" it to 120V, with some
amount of filtering and transient supression behavior.
