This zero-flux technology (Hall element) current sensor has a dual-range design covering small to large currents to accurately observe current waveforms. Whether the current fluctuation of the high-efficiency switching device, the current of the power-saving device as low as 1mA, or the high-speed transient current of the power-on, it can be handled. Excellent frequency response ability, can analyze and display the current waveform containing multiple frequency components, such as switching frequency, pulse waveform, etc., so as to meet the comprehensive measurement needs of complex current signals.
