Model  | Rated Input Current  | Rated Output Current  | Rated Sampling Resistance  | Rated Sampling Voltage  | Phase Shift  | Non-linearity  | Linear Range  | 
TA8595-01M  | 1A  | 1mA  | 100Ω  | 0.1V  | ≤60'  | ≤0.5%  | ≥2 times of the rated value  | 
TA8595-02M  | 1A  | 0.5mA  | 400Ω  | 0.2V  | ≤60'  | ≤0.5%  | 
● 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 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.
② The secondary circuit of the current transformer should not be open-circuited. Therefore, please do not install fuses.
