CR Magnetics Forums

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.

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.
