CT1-T fiche technique
Current Transducer CT 1-T
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).

Note :
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.
Features
Closed loop (compensated) current
transducer
Insulated plastic case recognized
according to UL 94-V0
Patent pending.
Advanced features
