Current Transducer CT 1-T

I_PN= 1 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).

· Static converters for DC motor drives

· Battery supplied applications

· Uninterruptible Power Supplies

(UPS)

· Switched Mode Power Supplies

· Power supplies for welding

applications.

Note :

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.
