STMicroelectronics AVS12 Automatic Voltage Switch Controller Datasheet

Q: What is the purpose of the AVS12 kit?

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

Q: What happens if the main power drops from 220V to 110V?

The triac control remains locked to the 220V mode to avoid high voltage spikes when voltage is restored.

AVS12 is an automatic mains selector (110/220V AC) to be used in SMPS<500W.
