FREESOR(飞轩)Китай
Using Hall effect and open-loop measurement principle, after TRMS calculation, the measured current is converted into DC current or voltage output proportional to the primary current, and the current sensor can measure DC, AC, pulse and various irregular waveforms of current under the condition of electrical isolation. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure and long-term stability.
