Details:
The AH951 series is a high-performance open-loop Hall-effect current sensor. It features an integrated low-impedance primary conductor, enabling it to measure currents up to 50A. This isolated current sensing chip utilizes the open-loop Hall-effect sensor principle. By routing the high-voltage current conductor within the package, the magnetic effect of the current generates a proportional magnetic field around the conductor being measured. This magnetic field is then sensed by the integrated magnetic sensor and converted into a processable proportional voltage signal. This voltage signal is then amplified by the built-in high-precision ADC. Digital calibration technology removes environmental variables such as temperature, noise, hysteresis, and nonlinearity. The resulting output voltage is nearly perfectly proportional to the measured current, enabling isolated current measurement. The AH951 is fully factory-programmed to ensure consistent module parameters, quality, and reliability. The measurement range is 10A to 50A. This product can be used for AC or DC current measurement.
