Overview
The AVS12 kit, produced by STMicroelectronics, is an automatic mains selector designed for use in Switch-Mode Power Supplies (SMPS) with a power rating of less than 500 watts. This kit consists of two devices: a controller and a TRIAC. The controller is optimized for low power consumption and high security triggering of the TRIAC, ensuring efficient and safe switching between 110V and 220V AC mains. The kit is fully compatible with both 50/60Hz power frequencies, making it versatile for various global power standards.
