Automatic Voltage Switch Smps < 300w

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 : TheController is optimized for lowconsumption 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,themode input desac- tivates this option this is the follower option. The TRIACis speciallydesigned for this 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.
