7. Typical Application and Performance Parameters:
See the table below for the application performance parameters shown in Figure 3.

Model	Rated Input Current	Rated Output Current	Rated Sampling Resistance	Rated Sampling Voltage	phase Shift	Non-linearity	Linear Range
TA3238-01M	1A	1mA	100Ω	0.1V	≤60'	≤0.5%	≥2 times of the rated value
TA3238-02M	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:
 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.
