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 :

• The Controller is optimized for low consumption

and high security triggering of the triac. When

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 restored to 230V.

tivates this option “this is the follower option”.

• The TRIAC is speciallydesigned forthis applica-

tion. An optimization between sensitivity and

dynamic parameters of the triac gate highly re-

duces the losses of supply resistor and allows

excellent immunity against line disturbances.
