Re: Classic Chargers Message #6 Posted by Jacques Laporte on 21 Jan 2011, 4:40 a.m., in response to message #1 by Alberto Fenini
Ciao Alberto,
Yes, in the past (2007 i think) I have done measures on the Classics transformer 82002A.
I wrote on my site that the output voltage of the constant current circuit is @ 15V DC (unloaded).
You can easily confirm that with a multimeter.
See photo below.
With the calc attached (the load) the voltage drops.
That's it !
I will open a working adapter this WE for you and measure the voltage at the Xformer's secondary.
That said, my HP calc site has become too huge (too much data) : errors are certain.
Thank you all to help me correct them!
