LEM have recently launched six separate families of LxSR transducers called LXS, LXSR, LES, LESR, LKSR, LPSR.
Based on LEM’s custom proprietary Hall-effect ASIC, the LxSR series transducers offer low offset drift of 3 to 14ppm/°C, combined with high levels of design flexibility.
All families provide options for an integrated voltage reference, an aperture and/or integrated primary conductors and fast over-current detection.
Designed for nominal currents from 1.5-50A, the LxSR series operates over a temperature range from -40 to +105°C.
The families achieve LEM’s benchmark performance through a patented arrangement of multiple Hall cells in addition to sophisticated offset cancelling techniques.
Each transducer is individually calibrated and sensitivity adjustments are stored in the ASIC’s One-Time-Programmable memory. This memory is also used to store a unique ID to provide full traceability of each ASIC.
