Notes : 1) 2) With a di/dt of 100 A/s A list of corresponding tests is available 000901/0 LEM Components w w w.lem.com Dimensions LB 1000-SI/SP2 (in mm. 1 mm = 0.0394 inch) Front view Left view Secondary terminals Terminal + : supply voltage + 15 V Terminal M : measure Terminal - : supply voltage - 15 V Connection Top view Mechanical characteristics * * * * General tolerance Fastening Primary through-hole Connection of secondary 0.5 mm 4 slots 7 mm 40 mm Faston 6.3 x 0.8 mm. Remarks * IS is positive when IP flows in the direction of the arrow. * Temperature of the primary conductor should not exceed 100C. * Dynamic performances (di/dt and response time) are best with a single bar completely filling the primary hole. LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice. |
