Conductor terminals are soldered together.
Pollution class 2, overvoltage category III.
Linearity data exclude the electrical offset.
Please refer to derating curves in the technical file to avoid excessive
core heating at high frequency.
Please consult characterisation report for more technical details and
application advice.
Operating at ±12V
≤
Vc < ±15V will reduce measuring range.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice.
