产品详情

  TBC-LTHA系列高精度闭环型电流传感器的初、次级之间是绝缘的,无位置误差,能真正测量分辨1000:1,用于精密测量直流、交流和脉冲电流。

  The TBC-LTHA Series current sensor is a closed loop device based on the measuring principle of the hall effect, 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, it uses for precision measurement of DC, AC and pulse current.

  2. General tolerance ±1mm.

  使用说明 Directions for use

  1. 产品箭头的方向为Ip方向。

  Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.

  2. 初级导体温度不应超过100℃。

  The primary conductor should be≤100℃.

  3. 母排完全充满初级穿孔时动态表现(di/dt和响应时间)为最佳。

  The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

  4. 为了达到最佳的磁耦合,初级线匝应绕在传感器顶部。

  The primary turns should be at the top of the sensor for the best magnetic coupling.
