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.
