产品详情
TBC2000LFB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。
TBC2000LFB 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 it uses for precision measurement of DC, AC and pulse current.

结构参数 Mechanical dimension(for reference only)
Remarks:
1. All dimensions are in mm.
2. General tolerance ±1mm.
使用说明 Directions for use
1. 在IP按箭头方向流动时,IS是正向。
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120℃。
The primary conductor should be≤120℃.
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.
