Table 1
Model | Rated Input Current | Rated Output Current | Rated Sampling Resistance R L | Rated Sampling Voltage | Non-linearity | Linear Range |
TA1338-01M | 50A | 50 mA | 40Ω | 2V | ≤0.2% | ≥ 1.5 times of the rated value |
TA1338-02M | 50A | 25 mA | 160Ω | 4V |
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.
