7. 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 |
TA4050A -01 | 400A | 0.4A | 10Ω | 4V | ≤30' | ≤0.5% | ≥3 times of the rated value |
TA4050A -02 | 400A | 0.2A | 25Ω | 5V | ≤30' | ≤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 Connect the primary winding of the current transformer in series with the measured current loop, and operate the secondary winding in near short-circuit mode.
② Do not allow the secondary winding of the current transformer to be open-circuited and do not install any fuse in the secondary circuit.
