Typical Usage (see the right Fig.1) and Technical Parameters:

Model	Rated Input current	Rated Output current	Rated sampling resistance	Rated sampling voltage	Non Linearity	Withstand Voltage
TA1526-1	50A	250mA	30 Om	7.5V	<2%	>6kV
TA1526-2	50A	100mA	150 Om	15V	<2%
TA1526-3	50A	50mA	600 Om	30V	<2%

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.
