7．Typical Application and Parameters:

The parameters in this application as shown in the  Fig. are listed in the table below:

● Notes:

a. In practical applications, it is recommended to use a sampling resistor that is smaller than or equal to the rated value given in the table above, as this can help to improve the non-linearity and phase shift of the device.

b. If the required current ratio is not listed in the table above, we can provide custom-made options to meet specific needs.

8．Attention:

① Connect the primary winding of the current transformer in series with the measured current loop, and operate the secondary winding in near short-circuit mode.

② Do not allow the secondary winding of the current transformer to be open-circuited and do not install any fuse in the secondary circuit.
