How to use the AVS kit

Introduction
The AVS08, AVS10 and AVS12 are automatic mains voltage selectors to be used in online
SMPS supplies with power up to 500 W. An AVS is made of two devices, a controller and an
AC switch.
The AC switch automatically modifies the structure of the input diode bridge in order to keep
the same DC voltage range.
