Mains Voltage Protector
Dear.
I'm trying to design a simple circuit that will be used as a mains voltage protector. In my country we have a really bad electricity service. Sometimes the electricity goes OFF and ON, ON and OFF, very quickly, which may harm electronic devices.
Also, the mains voltage here is 220V but it comes weak mostly, 180 and lower and even down to 100! due to the bad and old mains lines and network.
A switch mode 12V or 9V adapter with 100-240V AC input will be used to power the circuit, that will turn ON a relay as the electricity ON, and turn it OFF when the electricity starts going ON and OFF quickly. The circuit will wait after the electricity being continuously ON for about a minute then switching the relay ON again.
The appliances will be supplied from the relay.
I thought about using 555 timer, but didn't know how to do it.
Hope you understood me well.
Any help is strongly appreciated.
Best Regards,
Hazim
