Working Principle

The ACS714LLCTR-05B-T current transducer utilizes integrated Hall effect technology. It consists of a Hall effect integrated circuit, a one-turn current sensing coil, and a magnet to create a signal proportional to the measured current. When a current is applied to the coil, the magnetic field created will cause a deflection of the Hall element. This Hall element then generates a proportional voltage output that has a linear relationship to the input current.

The current transducer also has a voltage output that is proportional to the temperature. This output is used to cancel out any temperature-related errors in the output. The accuracy of the output is maintained at a high level using calibrations and temperature compensation. In addition, the protection against reverse polarity and the wide I2C interface voltage range makes the transducer suitable for a variety of applications.
