Hello everyone, I want to ask, I want to try to test my WCS1800 sensor but I am confused about where to get the current from because I want to try from 0-30 A. I don't have an Adjustable Power Supply for this and is there a circuit or other alternative to check my sensor is working properly in the current range? Thank you

 

You can thread a few strands of the wire through the hole in the sensor.
If you insert 3 strands, 10 A current source will be enough to test.
If you insert 6 strands, 5 A current source will be enough to test.
In both cases, the sensor will display such a current as a current of 30 A

Multiple passes of the current carrying conductor thru the sensor is a proven method of multiplying the sensitivity. It is by no means a new concept!!
