Hi guys Im planning to make an automatic failover system.
our power line is 220VAC and I want to consider 8% of that is already low voltage and it should turn on the backup power..
power cut off is easy to detect but Im asking idea on how to properly detect the low voltage....
anyone?
I will use PIC MCU for this experiment..
Thanks so much
