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 Controlleris optimized for low consumption and high security triggering of the triac. When connected to V SS , themode input activates an additionaloption “thelatchedoption”. 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 V DD ,t h emode input desac- tivates thisoption“this is thefolloweroption”.
  • 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.
