CT100-S_06 Datasheet, PDF (1/2 Pages) LEM – Current Transducer
Current Transducer CT 100-S
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 : 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.
