AK-C420L Datasheet, PDF (1/2 Pages) LEM – AC Current transducer

AC Current transducer AK-C420L
Transducer for the electronic measurement AC sinusoidal waveforms
current, with galvanic isolation between the primary (High power) and
the secondary circuits (Electronic circuit). Jumper selectable ranges
and 4-20mA current output.
