DK-B420 Datasheet, PDF (1/2 Pages) LEM – DC Current transducer DK-B020/420

DC Current transducer DK-B020/420
A split core transducer for the electronic measurement DC current,
with galvanic isolation between the primary (High power) and the
secondary circuits (Electronic circuit) with current output.
