Daviteq Electrical Sensing Technologies

Daviteq AC 5A current transducer is a transducer to convert the AC current from the Current Transformer (CT) to DULP
digital output so that it can connect to any wireless transmitter of Daviteq.

It can connect to any brand of CT on the market.

The AC current from CT will go thru a precision resistor to convert to voltage value in mV, then the electronics circuit
will convert the mV signal to digital value via the DULP interface which is read by the wireless transmitter.
