FREESOR(飞轩)China
Applying Hall effect and closed-loop Hall measurement principle, after TRCSM calculation, the measured current is converted into a DC current or voltage measurement module proportional to the output of the primary current, and the mixed current such as AC and DC is measured, and the primary and secondary sides are highly insulated. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure, easy installation, long-term stability and adapt to various working environments. Widely used in electric power, petroleum, coal, chemical, railway, communication, building automation and other industries of electrical equipment system control and testing.
