The LEM high precision product range covers transducers for nominal current measurements from 12.5 A to 25 kA, providing overall accuracy at 25°C from 1 ppm. These transducers have thermal offset drifts which are extremely low, from only 0.1 to 2.5 ppm/K. Transducers from 12.5 A to 60 A nominal can be used for PCB mounting, and Transducers from 60 A to 25 kA ae for panel or rack mounting. To obtain these exceptional performances, closed loop fluxgate technology has been used, coupled with a top-class current transformer. This combination enables precision current transducers having high accuracy and dynamic performance with a wide measuring range.
