Current transducers are devices that measure the current in an electrical circuit and convert it into a voltage that can be used for measurement, control and operation purposes. An example of a current transducer is the ACS711EEXLT-31AB-T. The device is designed to measure the current in a power circuit with an accuracy of 6.5%. Its purpose is to provide feedback for the control of various electrical systems.

Overview of the ACS711EEXLT-31AB-T

The ACS711EEXLT-31AB-T consists of two parts – a main portion that consists of a built-in current transformer and an external sensing element. The transducer measures current through an input coil connected to the power circuit, and the sensing element detects the generated voltage. The magnetic flux generated by the alternating current causes a small voltage to be generated in the sensing element, which is proportional to the current.
