Dear Sir,

Thank you for your interest in our product lines. The 604-1000T has 1000 turns so an input of 100AAC would yield an output of .1AAC. If you are looking for a split core CT with 3000 turns we have the CR3111-3000 which will take up to 100 AAC and saturates at 19 V RMS. The insulation voltage is 3500VAC/min.

I noticed you mentioned using a 1000 ohm burden resistor. Typically we would use a much smaller resistor since the accuracy of the CT improves as you decrease the burden resistor. Also, since most A to D converters take a 0-10 VDC input, you will need to use a rectifier circuit to condition your signal. I have attached our application guide that details how this circuit is constructed.


After you rectify your signal you can send it across a variable burden resistor to read to your converter. You will want to calibrate our CT using the variable burden.

I also wanted to mention that CR Magnetics offers packages that have the precision rectifier circuit built in, and are calibrated to your input you need. Our CR4111S-100 True RMS Current Transducer will take up to 100AAC and output 0-10VDC. This unit is best for VFD drives and chopped waveforms. Our CR4211S-100 will read the average RMS Current and output 0-10VDC. This is a self-powered unit. Please see the attached catalog pages.
