Dear Technical,
I'm looking for the Phase angle error or phase shift, ratio error, standard Accuracy class, and nominal linearity %. Where can I get these info? Thank you.
Best regard,
Thuan Truong.

Dear Valued Customer,
Please provide your burden and input current. We will then be able to get this information for you.

Dear Technical,
I just get back to this project. I want to use the CR8350-2000 with the max input current is 100A and burden resistor is 1.7 Ohm. I just wonder is there a set up to get reply alert through email? Thank you.
Best Regards,
Thuan Truong.

The CR8350-2000 has a DCR of 73 ohms and a turns ratio of 2000 developing a Vmax voltage of 31 volts. A 1.7 ohm resistor will cause a voltage level of 100/2000 * 1.7 or 85 mV. The transformer capability at that level of current is 31 – (100/2000)*73 or 31 – 3.65, or 27.35 volts. This application should be better than 0.5% accurate. You would still be linear using a resistor up to 27.35/100*2000 or 547 ohms for a 100 amp input.
