Pls, have a look at this description of Signetics 25000 series 9046 XN 
component: http://pichotjm.free.fr/humr/2.html
Can you explain me, what is Vff?  Is it a good idea to decrease this voltage 
in order to increase reliability?
But what will happen with our 50 Hz european supply?
I need help...

(please, answer with simple english)
