7. Typical Application and Technical Parameters:

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


The parameters are listed in table below.
 

Model	Rated Input Current	Rated Output Current	Rated Sampling Resistance	Rated Sampling Voltage	Phase Shift	Non Linearity	Linear Range	Withstand Voltage
TA5A/0.1A	5A	100mA	30Ω	3V	≤30'	≤0.5%	3 times of the rated value	≥2KV
TA5A/1A	5A	1A	0.3Ω	0.3V

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.
