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 connected to VSS, the mode input activates an 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. When connected to VDD, the mode input desactivates this option “this is the follower option”.

? The TRIAC is specially designed forthis application. An optimization between sensitivity and dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against line disturbances.
