High-performance current transducers

March 17th, 2014, Published in Articles: EngineerIT


LEM of Geneva, Switzerland, has released a range of high accuracy AC/DC current transducers, designated ‘Ultrastab’. Transducers are available for the measurement of current from 12,5 A to 24 000 A. Linearity errors denver-248-03-2014are of the order of 4 ppm, and their temperature coefficient is 2 ppm/ºK. Frequency response is typically DC to 500 kHz, with di/dt accurately followed 20 A/µs, and response time to 90% of the nominal current is typically 1 µs. Applications include feed-back elements in precision current regulated devices, calibration units, precise and high stability inverters, energy management, and medical equipment.
