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 (eg. primary busbar, 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. 7June2021/version 14 LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice LEM International SA Chemin des Aulx 8 1228 PLAN-LES-OUATES Switzerland www.lem.com Dimensions LAH 100-P (in mm) Connection IP IS RM 0V +UC -UC dCI 11.75 Number of primary turns 1 Primary current IP N [ A ] nominal maximum IP [ A ] 100 160 7June2021/version 14 11.75 Nominal output currrent Turns ratio Primary resistance Primary insertion inductance IS N [ mA ] NP/NS RP [ mΩ ] LP [ µH ] 50 1 : 2000 0.08 0.007 Mechanical characteristics ● General tolerance ● Fastening & connection of primary Recommended PCB hole ● Fastening & connection of secondary Recommended PCB hole dCp Remarks ±0.2 mm 6 pins 1.4 x 1 mm 2 mm 3 pins 0.7 x 0.6 mm 1.2 mm ● IS is positive when IP flows from terminals “IN” to terminals “OUT”. ● The jumper temperature and PCB should not exceed 100°C. ● This is a standard model.
