TBC-LTHA High Accuracy Closed Loop Hall Effect Current Sensor
The TBC-LTHA Series current sensor is a closed loop device uses for precision measurement of DC, AC and pulse current. It can really measure resolution 1000:1. The size of primary doesn’t affect test precision, no matter the location of primary in the hole of current sensor. This series current sensor has rated current input between 50A and 300A, meansure range upto 900A. It has 0.2% accuracy, very reliable. Available for appearance customization.

Remarks：
1. All dimensions are in mm.
2. General tolerance ±1mm
|
Directions for use |
1. Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.
2. The primary conductor should be≤100℃.
3. The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.
4. The primary turns should be at the top of the sensor for the best magnetic coupling.
