Hello every one
I want to use CT for measuring current of one dc motor(a bout 0 ~30 A-12 or 24 VDC) and at last sensing it with ADC(I don’t want measure it exactly I want sense over load current ,continues current ,no load current and whit out current from each other ) please recommend me one circuit a bout my problem
Tank you
Best regard

If you mean a Current Transformer by CT, then you have to realise that a CT only works for AC current, not DC.
But of course you can use other devices, from a series resistor to Hall current sensors, to measure DC current. _________________ Adrian Jansen
