- 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
- General tolerance ± 0.3 mm
- Fastening 2 x M5 screws
- Connection of primary M5 threaded studs
- Connection of secondary M5 threaded studs
- Fastening torque 2.2 Nm or 1.62 Lb - Ft Dimensions CT 25-T (in mm. 1 mm = 0.0394 inch) Secondary terminals Terminal : supply voltage + 15 V Terminal M : measure Terminal : 0 V Terminal : supply voltage - 15 V Connection Front view Top view Left view LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
