AUTOMATIC VOLTAGE SWITCH (SMPS < 200W) CONTROLLER 50/60Hz FULL COMPATIBILITY INTEGRATED VOLTAGE REGULATOR TRIGGERING PULSE TRAIN OF THE TRIAC PARASITIC FILTER LOW POWER CONSUMPTION TRIAC HIGH EFFICIENCY AND SAFETY SWITCHING UNINSULATED PACKAGE : AVS08CB INSULATED PACKAGE 2500V( RMS ): AVS08CBI VDRM = ± 500 V IT(RMS) :5 A

DESCRIPTION

The AVS08 kit is an automatic mains selector (110/220V AC) to be used in SMPS < 200 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. If the main power drops from 220V to 110V, the triac control remains locked to the 220V mode and avoids any high voltage spike when the voltage is restored to 220V. When connected to V DD , themode input desacti- vates thisoption.
  • The TRIAC is specially designed for this applica- tion. An optimization between sensitivity and dy- namic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against disturbances.
