Max value of current from the 100A Coil Transform at 100A circuit current. #95

Hi there, What will the current output of the closed type 0-100A type coil transformer if the current in the circuit is the max at 100A? I know the theory behind the coil transformer used with PZEM module to find the value of current in the circuit. But I don't know the number of turns in the closed type coil transformer given along with pzem?

To avoid confussions, the following is the pic of the pzem module I have. image

The CT ratio is 1000:1 (100A primary => 100mA secondary). You can see it in the label of the split current transformer (for example here), as the rest of the hardware is the same for both CT versions.
