Hi everyone, I am trying to monitor the current output of the 230v socket outlet using current sensor and a Monitoring system and its equipped with transmitter (4-20mA). Once it reach over 20mA it will indicate as overload. The voltage across the 500ohms resistor (parallel with the current transformer) is 0.449vac at 1A. and 2.245vac at 5A. how do i convert AC voltage to output DC 1-5v? I wan 1-5vdc because of the transmitter. I tried the circuit showed in the link but it doesn't work for me. The circuit they used is 0-50A and output is 3vdc, the diode i used is IN4007. I do not understand the calculation of the circuit. https://forum.sparkfun.com/viewtopic.php?f=14&t=28775&start=15#p129154 Transformer im using: http://www.mouser.com/catalog/specsheets/CST-1005.pdf Thank you!
