Hi, I am currently trying to make an arduino based Power Meter. I will buy the SCT010T-D ct from YHDC. My question is the following. The ct says it has a DC 5v output at 5-10-20 etc Amps depending on the model. Does that mean the output is a sine wave with dc offset (which requires more calculations to get the rms value) or is it pure DC which can be dirrectly measured and converted through an arduino ?
SCT from YHDC On this link you can find the ct and a diagram of its circuit.
Thanks in advance

 

Hello,

Did you look in the datasheet?
There is a rectifier in the sensor, so the output is DC:

Yes I seen it and that fact that it is dc is stated at the manual but is it pure dc (without ripples) or a sine wave with dc offset above 0v like in the picture? Or am I understanding something wrong?

 

Hello,

The internal schematic shows a bridge rectifier with a capacitor for smoothing.
The output will be DC with a small ripple.
Read the pages 38 to 40 of the attached course.
