● 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.
8. Attention :
① Connect the primary of the current transformer in series with the measured current loop, and operate the secondary in near short circuit mode.
② Do not allow the secondary of the current transformer to be open circuited and do not install any fuse on the secondary.
