Common Accuracy Hall Effect Dc Current Sensor TBC-LTA Series Custom-made,two type of connector for choose.
The TBC-LTA Series 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 doesn’t affect test precision, no matter the location of primary in the hole of current sensor, It can really measure resolution 1000:1 and uses for precision measurement of DC, AC and pulse current.

| Mechanical dimension(for reference only) |
Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm
| Directions for use |
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.
