LA系列 – 電流傳感器
LA系列電流傳感器采用閉環霍爾效應轉換器設計，可精確測量直流、交流及脈沖電流，同時在一次側與二次側電路間提供增強型電隔離。該系列覆蓋廣泛的額定電流范圍（根據型號不同，從5安培至500安培不等），提供多種外形尺寸和安裝選項，以滿足工業及鐵路環境中多樣化的集成需求。
大多數LA系列傳感器專為印刷電路板（PCB）安裝設計，采用緊湊型外殼，其主導體孔徑適配插頭式連接，具體尺寸因型號而異。這類PCB安裝式傳感器以卓越的精度和快速響應時間著稱，使其成為工業應用的理想選擇。
若干高電流型號（如LA 205、LA 305和LA 306）專為面板安裝設計，配備更大的初級孔徑以適應更粗的導體。其中LA 306型號特別面向工業應用領域。
LA 200?500 SD是LA系列中的獨特產品。這款分體式面板安裝電流傳感器配備67×67毫米大開口，便于在現有導體周圍輕松安裝。基于閉環霍爾效應技術，它具有高精度和快速響應特性，特別適用于牽引和鐵路電流測量應用。
在整個LA系列中，閉環架構、電隔離與優化機械設計的結合，確保了在嚴苛環境中實現可靠精準的電流測量。
