I've looking for more sensors like the one i'm using and i found tihis on: http://www.soselectronic.com/a_info/resource/a/pdf/AC1050.pdf.
It looks its almost the same and has a more detailed datasheet.
I have had a burden resistor at the output of the sensor to measure current, but if i use the value given for 100 ohm at the output it doesn't give even close to the right result. (I am measuring the current with another equipment.)
Does anyone have used this type of sensors?
