I have a mains adaptor (marked as "model SPN 4079A") which is made in
the UK and which is marked ... "OUTPUT 12.5v 400mA".
I plugged it in the mains here in the UK and measured the voltage at
the end with the round concentric applicance plug. It was about 17.3
This seems rather a too high. I am worried this will damage a unit I
have got which needs 12 volts and which I was going to use this
Could this high 17.3 volt reading be entirely due to the lack of load
on the adapter or is 17.3 volts too high even for that?
Unfortunately I forget where this SPN 4079A adaptor came from.
Google is not my friend either! :-(
