Current Transducer CT 10-T

I_PN= 10 A

For very accurate measurements of currents : DC, AC, pulsed...,

with a galvanic isolation between the primary circuit (high power)

and the secondary circuit (electronic circuit).

Notes : 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

· V_OUTis positive when I_Pflows in the direction of the arrow.

· This transducer induces into the primary circuit a square

wave of 35 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...),
