AC Current transducer APR-B10
Split core transducer for the electronic measurement distorted AC
waveforms current, with galvanic isolation between the primary (High
power) and the secondary circuits (Electronic circuit). Switch selectable
ranges and True RMS 0-5V and 0-10V switch selectable voltage output.
