  • VOUT is positive when IP flows in the direction of the arrow.
  • This transducer induces into the primary circuit a square wave of 14 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. Mechanical characteristics
