1．Features: 

① The transformer has a built-in primary coil and standard input and output terminals, which makes it easy to use and gives it an elegant appearance.

② It is completely sealed, has strong mechanical and environmental endurance, strong dielectric strength, high accuracy, and is safe and reliable.   

2．Ambient Conditions:

① Ambient temperature: -55℃～+85℃;

② Relative humidity:≤90% at 40℃;

③ Atmospheric pressure:860～1060mbar(about 650～800mmHg).

3．Operating Frequency Range: 20Hz~1kHz

4．Insulation Thermal Class：Class F (155℃)

5．Safety features:

7．Typical Application and Technical Parameters：

The sampling voltage is obtained directly by using a resistor (as shown in Fig.1).

The parameters are listed in table below:              

● Notes:

a. In practical applications, the sampling resistor should be smaller than or equal to rated value given in table above in order to improve non-linearity and phase shift.

b. We can have it customer-made if required current ratio is not listed in the table above.

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.
