TRIAC

The AVS12 kit is an automatic mains selector

(110/220V AC) to be used in SMPS < 500 W. It is

composed of 2 devices :

■

The Controller is optimized for low

consumption and high security triggering of the

triac. When connected to V

SS

, 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 V

DD

, the mode input

desactivates this option.

■

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.
