              TBC1000LFA高精度閉環型霍爾電流傳感器的初、次級之間是絕緣的,無位置誤差,能真正測量分辨1000:1,用于精密測量直流、交流和脈沖電流。

              The TBC1000LFA 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.

              1. 在IP按箭頭方向流動時,IS是正向。

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

              2. 初級導體溫度不應超過120℃。

              The primary conductor should be≤120℃.

              3. 母排完全充滿初級穿孔時動態表現(di/dt和響應時間)為最佳。

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