New hall effect-based current transducer range materializes technology breakthrough

LEM has launched six new current transducer series to add to their already large portfolio. The new transducer families are called; LXS, LXSR, LES, LESR, LKSR, LPSR. Each transducer can be mounted on printed circuit boards for non-intrusive and isolated measurements of DC, AC and pulsed nominal currents from 1.5A to 50A thanks to a multi-range configuration. These closed-loop current transducers are based on a LEM custom proprietary patented Hall Effect ASIC, allowing them to perform at the level of fluxgate transducers. The LxSR current transducer range has an offset drift that is over four times lower than the previous generation of closed-loop transducers based on Hall cells. The value reached is very similar to those using fluxgate. Offset drift achieves a value between 4ppm/OC to 14ppm/OC. LEM’s spinning technique and specialist ICs have been significant contributors to these drastic improvements. With the products’ performance of fluxgate, customers are not only provided with better control and increased system efficiency, but also a significantly lower price.
