High-Current DC Transducers Enable Bipolar Measurements

LEM International’s DH family of dc current transducers offers precise measurement of bipolar currents from 500 A to 2000 A. Absolute accuracy is better than 1% of the nominal current value. The transducers output the bipolar measurement value through an industry standard 4-mA to 20-mA loop-powered output. Measuring 174 mm x 86 mm x 54.1 mm, these split-core transducers combine Hall-effect technology and signal conditioning in a single housing with a large rectangular sensing aperture for non-contact measurement.
