Notes :
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
2)
With a di/dt of 60 A/µs.

Remarks
?V OUT is positive when I P flows in the direction of the arrow.?This transducer induces into the primary circuit a square
wave of 3.5 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
