Current Transformer Module 5A AC

This is an onboard adjustable precision AC current transformer. 

This module is equipped with the ZMCT103C series of small high-precision current transformers and high-precision op amp circuits for accurate sampling and proper compensation of signals. It is convenient for signal acquisition of AC power within 5A. The corresponding output analog AC signal can be adjusted. The required output voltage can be adjusted according to the potentiometer (adjusting the amplification ratio, the amplification range is 0-100 times), but the maximum voltage at the output (OUT) will not exceed 1/2 VCC.

Dimensions: 38mm x 18.5mm

Instructions:

During measurement, the signal conductor to be tested passes through the transformer hole, VCC and GND are connected to the DC 5-30V power supply, VOUT and GND are connected to the oscilloscope, and the potentiometer is adjusted to get the waveform you want. The amplitude of the waveform will follow the measured current increases, but the maximum does not exceed 1/2VCC.
The following figure shows the waveform measured when VCC is connected to a 5V power supply and one of the 60W soldering irons passes through the round hole of the transformer:
