Current Transducer LT 10000-S
For the electronic measurement of currents : DC, AC, pulsed...,
with a galvanic isolation between the primary circuit (high power)
and the secondary circuit (electronic circuit).

flows in the direction of the arrow.
Temperature of the primary conductor should not exceed
100C.
Dynamic performances (di/dt and response time) are best
with a primary bar in the center of the through-hole.
This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
