7. Typical Application and Performance Parameters:
TV0914-1M is a current-mode voltage transformer. Typical applications are shown in Figure 2 on the right and Figure 3 on the lower right. The performance parameters are shown in the table below.
Usage | Model | Input Voltage | Output Voltage | Phase Shift | Non-linearity | Linear Range | Rated Current | Withstand Voltage(kV) |
Used as in Fig. 2 | TV0914-1M | ≤1000Vac | ≤0. 625 Vac | ≤ 40 ' | ≤0.2 5 % | 1.5 times of the rated value | 2mA/2mA | ≥2 |
Used as in Fig. 3 | TV0914-1M | ≤1000Vac | ≤1/2 IC’s power supply | ≤5' | ≤0.1% | 2 times of the rated value |
8. Attention:
This voltage transformer model is a current-type transformer. Therefore, an open circuit is not permitted in the secondary circuit, and no fuse should be connected in the secondary circuit.
