Product Description
LEM GO-SME Series Current Transducer
The GO-SME series is a range of current transducers designed for the electronic measurement of DC, AC, and pulsed currents. They provide galvanic separation between the primary and secondary circuits, making them ideal for applications requiring high insulation and immunity to external interference. Their extremely low profile and small size make them space-saving solutions for various electronic systems.
