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 Controller is optimized for low consumption and high security triggering of the triac. When connected to VSS, the mode input activates an additional option. 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 VDD, the mode input desactivates this option.
PIN CONNECTION
* The TRIAC is specially designed for this application. An optimization between sensitivity and dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against disturbances.
