On the other hand, measured values are part of a statistical distribution that can be specified by an interval with upper and lower limits and a probability for measured values to lie within this interval. Unless otherwise stated (e.g. “100 % tested”), the LEM definition for such intervals designated with “min” and “max” is that the probability for values of samples to lie in this interval is 99.73 %. For a normal (Gaussian) distribution, this corresponds to an interval between −3 sigma and +3 sigma. If “typical” values are not obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to an interval between −sigma and +sigma for a normal distribution. Typical, maximal and minimal values are determined during the initial characterization of a product.

  • General tolerance 0.5 mm
  • Transducer fastening 8 holes ⌀ 0.64 mm Remarks
  • VS is positive when a positive voltage is applied on +HV.
  • The transducer is directly connected to the primary voltage.
  • Care must be taken to maintain the creepage and clearance distances with the board design using proper PCB techniques.
  • Installation of the transducer is to be done without primary or secondary voltage present
  • Installation of the transducer must be done unless otherwise specified on the datasheet, according to LEM Transducer Generic Mounting Rules. Please refer to LEM document N°ANE120504 available on our Web site: Products/Product Documentation.
  • This is a standard model. For different versions (supply voltages, sensitivity, unidirectional measurements...), please contact us. Dimensions (in mm) Safety This transducer must be used in limited-energy secondary circuits according to IEC 61010-1. Caution This transducer must be used in electric/electronic equipment with respect to applicable standards and safety requirements in accordance with the manufacturer’s operating instructions. Caution, risk of electrical shock When operating the transducer, certain parts of the module can carry hazardous voltage (e.g. primary connections, power supply). Ignoring this warning can lead to injury and/ or cause serious damage. This transducer is a build-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used. Main supply must be able to be disconnected. All installations, maintenance and servicing operations must be carried out by trained operators. Failure to observe the installation instructions may compromise the protection provided by the unit. Connection dCp (mm)dCI (mm) 9.1 10
