7.Typical Usages and Technical Parameters.

The sampling voltage is obtained directly by using a resistor(as shown in the right figure).
The parameters are listed in table below.

8.Attention:

• The primary of the current transformer must be connected in series with the loop of the measured current. The secondary should operate in a mode of near short circuit.
• The secondary of the current transformer is not allowed to be open circuit, Do Not install any fuse.
