Open Loop Current Sensor

The open-loop Hall current sensor is that the magnetic flux generated by the primary current is Concentrated in the magnetic core,detected and processed by the Hall element,and finally the output Terminal can accurately reflect the change of the primary current,It has the advantages of fast response time,low power consumption,wide temperature range,and low cost,The maximum current can be measured up to 100KA.Widely used in welding machine,frequency conversion.power supply,drive,and other monitoring.
