Product Description
Product Overview
The LEM HO-P series are Hall effect current transducers designed for the electronic measurement of DC, AC, and pulsed currents. They provide galvanic separation between the primary and secondary circuits, offering a compact, space-saving solution with high insulation capability and fast response. These transducers are ideal for applications requiring precise current measurement with a single power supply and features like over-current detection.
