Input Current 10-1000A Closed Loop Hall Effect Sensor Low Current Hall Effect Sensor
TBC1000LF high precision Closed Loop Hall Effect Current Sensor
The TBC1000LF current sensor is a closed loop device based on the measuring principle of the hall effect and null balance method ,with a galvanic isolation between primary and secondary circuit, the size of primary not affect test precision, no matter the location of primary in the hole of current sensor, It can really measure resolution 1000:1 and it uses for precision measurement of DC, AC and pulse current.
