Split-Core Transducers Perform High-Current Bipolar Measurement

Measuring 174 mm x 86 mm x 54.1 mm, the DH family of split-core, dc-current transducers measure bipolar currents up to 2 kA via a combination of Hall-effect technology and signal conditioning in a single housing with a large rectangular sensing aperture for non-contact measurement. The components offer a choice of primary current measurement ranges from 500A to 2 kA and provide an absolute accuracy better than 1% of the nominal current value. The transducers output the bipolar measurement value through an industry standard 4 mA to 20 mA output and feature a loop-powered circuit that minimizes external wiring. LEM USA INC., Milwaukee, WI.
