Please look at the following company website:
http://www.prodisplay.com/intelligent-glass-technical.html
At the bottom there is a diagram showing a transformer with the smart glass (DVG) as a load. The smart glass is basically a capacitor.
So my questions:-
Q1. The manufacturer claims the power consumed is 7W. Should this not be 7VA?
Q2. Also, what power rating should the transformer have in this case? For a capacitive load, the Power Factor would be 0, is that right?
Q3. Or does the transformer mean that the load (as seen from the mains) is purely inductive?
Help..!
