RH100-S Datasheet, PDF (1/2 Pages) LEM – Coreless Coil Current Transducer RH 100~1000-S

Coreless Coil Current Transducer
RH 100 .. 1000-S
For the electronic measurement of currents: AC, pulsed, mixed, with
a galvanic isolation between the primary circuit (high power) and the
secondary circuit (electronic circuit).
