TA0913-1M	5A	5mA	150 Om	0.75V	<15`	<0.2%	>1.5 times of rated value	>6kV
TA0913-2M	5A	2.5mA	600 Om	1.5V	<10`

Table 2

Model	Rated Input current	Rated Output current	Rated sampling voltage	Phase Shift	Non Linearity	Linear Range	Withstand Voltage
TA0913-1M	5A	5mA	<1/2 IC`s power supply	<5`	<0.1%	>2 times of rated value	>6kV
TA0913-2M	5A	2.5mA

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.
