DESCRIPTION
The AVS10 kit is an automatic mains selector
(110/220V AC) to be used in SMPS < 300 W. It
is composedof 2 devices :
• The Controller is optimized for low consump-
tion and high security triggering of the triac.
When connected to V
SS
, the mode input activates an additional option. If the main power
drops from 220V to 110V, the triac control remains locked to the 220V mode and avoids
any high voltage spike when the voltage is restored to 220V.
When connected to V
DD
, the mode input de-
sactivates this option.
• The TRIAC is specially designed for this application. An optimization between sensitivity and
dynamic parameters of the triac gate highly
reduces the losses of supply resistor and allows excellent immunity against disturbances.
