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 :

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 restored to 230V.

dynamic parameters of the triac gate highly re-
duces the losses of supply resistor and allows
excellent immunity against line disturbances.
