HTY50-P Datasheet, PDF (1/2 Pages) LEM – Current Transducer HTY 50~100-P

Current Transducer HTY 50 .. 100-P
I_PN = 50 .. 100 A
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).
