DESCRIPTION
The AVS20 (AVS200) kit is an automatic mains
selector (120/230V AC) to be used in SMPS with
input power <300 W. It is composed of 2 devices :
• TheControlleris optimizedforlowconsumption
and high security triggering of the triac. When
connected to V
additional option “the latched option”. If the
main power drops from 230V to 120V,the triac
control remains locked to the 230V mode and
avoids any high voltage spike when the voltage
is restoredto 230V.
When connectedto V
tivates thisoption “thisis the follower option”.
• The TRIACis speciallydesignedforthis application. An optimization between sensitivity and
dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows
excellent immunityagainst line disturbances.
