FREESOR(飞轩)China
A new type of current sensor based on the principle of magnetic modulation has good stability of small current, high insulation between primary and secondary, and strong anti-interference ability. After signal conversion, it can be directly collected and accepted by PLC, secondary instrument and other acquisition devices, and is used in signal system, line detection, leakage monitoring system, current difference measurement.
