LA100-P from LEM is a closed-loop Hall effect current sensor measuring 0-100A with +\/-0.45% accuracy. 1:2000 turns ratio. PCB through-hole mount. Bandwidth DC to >200kHz.<\/p>\n

Principio de funcionamiento<\/h2>\n

Closed-loop Hall effect: primary current generates magnetic field sensed by Hall element. Compensation coil driven by amplifier cancels the field. Secondary current is proportional to primary current (1:2000). Closed-loop provides high accuracy and linearity.<\/p>\n
