• IS is positive when IP flows in the direction of the arrow.
• Temperature of the primary conductor should not exceed
100°C.
• Dynamic performances (di/dt and response time) are best
with a single bar completely filling the primary hole.
• This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
