Current Transducers, HY 50-P/SP1

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).

50 A

Notes : 1) Pollution class 2, overvoltage category III

2) Linearity data exclude the electrical offset.

3) Please refer to derating curves in the technical file to avoid excessive

core heating at high frequency

4) Please consult characterisation report for more techinical details and

application advises.
