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:
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.
