LEM AK50B5

AC Current transducer AK-B-
IPN = 10..200A
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 self powered transducers.
