HY5-P Datasheet, PDF (1/2 Pages) LEM – Current Transducers HY 5 to 25-P

Current Transducers HY 5 to 25-P
For the electronic measurement of currents : DC, AC, pulsed, mixed,
with a galvanic isolation between the primary circuit
(high power) and the secondary circuit (electronic circuit).

2) _{Pollution class 2, overvoltage category III.}
3) _{Linearity data exclude the electrical offset.}
4) _{Please refer to derating curves in the technical file to avoid excessive}
core heating at high frequency.
5) _{Please consult characterisation report for more technical details and}
application advice.
6) _{Operating at ±12V ≤ Vc < ±15V will reduce measuring range.}
