The ACS770LCB-100U-PSF-T current transducer operates in a wide range of operating environments, making it an ideal solution for many applications. It features industry-leading accuracy (127ppm for 10V inputs), low power consumption (4mA power up, 2mA in operating mode), and high temperature adaptation (operating from -40°C to 85°C). The sensor also has excellent temperature stability, providing good accuracy over broad temperature ranges. Additionally, its robust isolation voltage rating of 5kV in accordance with IEC 60950 ensures resistance to noise and electromagnetic interference.

The ACS770LCB-100U-PSF-T current transducer utilizes a Hall effect-based integrated circuit (IC) to sense current. The Hall device is placed in the primary winding of a transformers and receives a magnetic field proportional to the current in the winding. This magnetic field is sensed by the Hall device and converted to a proportional voltage that is fed back to the IC. The IC amplifies the voltage signal, provides offset and gain adjustment, filters the signal, and provides a digital output, which can be used to read the current. The integrated digital interface, features including PWM, aEnable/Disable, and fault detection, and real-time dynamic sampling rate adjustment, allows the application to be configured to meet various customer requirements.
