Notes:

a. In practical applications, the sampling resistance should be less than or equal to the rated value given in the above table, which will improve the nonlinearity and phase shift;

b. If the conversion ratio required by the user is different from the above, it can be customized according to the user's requirements.

8Attention:

 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.

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