产品详情
TBC-EH 系列高精度霍尔电流传感器的初、次级之间是绝缘的，无位置误差，能真正测量分辨 1000：1，用于三相精密测量直流、交流和脉冲电流。
The TBC-EH 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 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.

Remarks：
1. All dimensions are in mm.
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.
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.
5. 当待测电流从传感器穿过，即可在输出端测得电压大小。(注意：错误的接线可能导致传感器损坏)。
When the current will be measured goes through a sensor, the voltage will be measured at the output end.
(Note: The false wiring may result in the damage of the sensor)
6. 可按用户需求定制不同额定输入电流和输出电流的传感器。
Custom design in the different rated input current and the output current are available.
