Null Balance Closed Loop Hall Effect Current Sensor High Precision TBC1000LF
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.

TBC1000LF high precision Closed Loop Hall Effect Current Sensor
Directions
Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.
The primary conductor should be≤120℃.
The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.
