Hi Tom,
Wondering if there is any easy way I can connect a current transformer to one of my analog inputs for a load meter? The load meter signal out of my drive is all over the place. I think I would be better off just monitoring current input to drive.
Did a little googling on how to convert the output of a CT to DC voltage and there seems to be quite a lot of different opinions and circuits out there. People seem to run into trouble using diodes as it chops off the lower part of the signal.
Wonder if I could just use a CT with a resistor across it and then connect leads to kanalog ground and one of the analog inputs? This would be ac signal. Would I be able to use C code to convert this? Would the init program loop fast enough to do this accurately? Or am i better off with some kinda circuit to give me DC signal? If so what would you recommend? Thanks.
Mark
