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

Isolation characteristics

Isolation application example

The transducer can be used according to EN 50178 and IEC 61010-1 standards under following conditions

(for example):

The creepage distance and clearance of the transducer mounted on a PCB are greater than 8 mm only if the primary

circuit tracks stay out of the shaded area shown below:
