AIT500-SG has a high gain and measurement accuracy in the full bandwidth range, due to theapplicationofthe multi-point zero-flux technology system and high-frequency ripple sensing channel ontopof currentlyexisting DC sensor technology. The multi-point zero-flux technology system secures the high accuracy by utilizing thetechnologycombination of exciting magnetic flux closed-loop control, self-excited magnetic fluxgateandmulti-closed-loop control that realizes the closed-loop control between excitation magnetic fluxandAC/DCmagnetic flux generated by primary current, while the high-frequency ripple sensing channel allowsthesensor to have the high performance over the full bandwidth range.
