Current Transducer LT 2005-S
IPN = 2000 A
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).

Mechanical characteristics
Remarks
· General tolerance
· Fastening
· Primary through-hole
· Connection of secondary
Fastening torque
± 0.5 mm
· IS is positive when IP flows in the direction of the arrow.
· Temperature of the primary conductor should not exceed
100°C.
· Dynamic performances (di/dt and response time) are best
with a single bar completely filling the primary hole.
· This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
