AP-B420L Datasheet, PDF (1/2 Pages) LEM – AC Current transducer AP-B420L

AC Current transducer AP-B420L
Split core transducer for the electronic measurement AC waveforms
current, with galvanic isolation between the primary (High power) and
the secondary circuits (Electronic circuit). Switch selectable ranges
and RMS 4-20mA current output.
