Note :
1) If the short-circuit has a duration more than 1 s, the primary current of
the supply voltage must be interrupted for a short time to restore the
transducer to proper working order. The internal protection is done by
PTC resistors.

Remarks
VOUT is positive when IP flows in the direction of the arrow.
This transducer induces into the primary circuit a square
wave of 70 mV amplitude (frequency 220 Hz). This voltage
can induce an AC current in the primary if the primary
impedance is low.
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.
