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:

 The primary of the current transformer should be connected in series with the circuit being measured, and the secondary should work close to a short circuit condition.

The secondary circuit of the current transformer should not be open-circuited. Therefore, please do not install fuses.
