*General tolerance 0.2 mm *Primary through-hole 17 x 11 mm *Fastening & connection of primary 4 pins 0.63 x 0.56 mm
Recommended PCB hole *Supplementary fastening Recommended PCB hole Recommended screws LEM code 0.9 mm 2 holes 1.75 mm 2.4 mm K A 22 x 6 47.30.60.006.0
Remarks
*IS is positive when IP flows in the direction of the arrow. *Temperature of the primary conductor should not exceed
90C. *Dynamic performances (di/dt and response time) are best with a primary bar in low position in the through-hole. *In order to achieve the best magnetic coupling, the primary windings have to be wound over the top edge of the device. *This is a standard model. For different versions (supply voltages, turns ratios, unidirectional measurements...), please contact us.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
