AK-B420L Datasheet, PDF (1/2 Pages) LEM – AC Current transducer
AC Current transducer AK-B420L
A Split Core 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.
IPN = 2 .. 200A
