LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice.

Current Transducer LTS 15-NP

For the electronic measurement of currents : DC, AC, pulsed, mixed,

with a galvanic isolation between the primary circuit (high power)

and the secondary circuit (electronic circuit).
