High Precision 1:2000 Current Transformer 5A-2.5mA PCB Mount
Current transformers are used in transformer-rated energy meters to measure the total power consumed and the current measure flow. Transformer-rated energy meters are different from self-contained energy meters used within homes as the electric energy involved is very low. When the current involved is more than 200 Amperes, as with most industries and factories, transformer-rated meters with current transformers are required.

Note:
1.Output voltage is proportional to the derivative(di/dt)of the input current based on the Rogowski Coil principle.
2.All current and voltages assumed to be sinusoidal waveforms at Fr, the constant rated frequency in Hz, measured as RMS value.
3.Accuracy class per IEC60044-1Table 11.
4.Ipri=Rated primary current.
5.Iout=Rated secondary current.
6.Iprimax=Sensed max primary current.
7.Loutmax=Sensed max secondary current.
8.RL=Terminating resistance. Varying terminating resistance increases or decreases output Voltage /Ampers according to following
equation RL=Vout*Nsec/Ipri
