Hangzhi AIT300-SG is a 300 Amp High Precision Current Transducer with an accuracy of 10ppm (ten parts per million.) The multi-point zero-flux technology system applied in this high-precision DC transducer enables zero-flux closed loop control of excitation flux, DC flux and AC flux, and can detect high-frequency ripple by constructing a high-frequency ripple sensing channel, so that the transducer can achieve high gains and measuring accuracy over the full bandwidth.
