Hello everyone,
I need to monitor the mains with setpoint and I need an isolation too. I need a digital signal as output. When the mains is above the setpoint, I get a '1' and when below the setpoint I get a '0'. I am using opamp (with hysteresis) for the monitoring.
I have posted two basic circuits that I think maybe cost effective that I would like to choose from but if you have a better circuit, I'm open to your suggestion.
The circuit with a transformer is basically a switched mode converter with no feedback.
Please what do you think of the circuits I have posted? If you were to select one from the two, which would you prefer? If you have a better circuit, please suggest to me.
Thanks in anticipation.
