Transducer measures currents up to 350ARMS

This new transducer is only 56 mm high. It features a wide maximum bandwidth of DC to 50kHz and an overall accuracy of better than ±0.7 per cent at a primary nominal RMS current of 350A. Typical linearity error is ±0.1 per cent at 350A and the maximum offset temperature drift is 500 microamps from -40 to +85˚C. The closed-loop Hall-effect technology results in no insertion losses and a fast response time of less than 1 microsecond.

The transducer’s aperture accepts busbars up to 13 x 30mm. A Molex series 70543 plug is offered as standard for the secondary connections, for a robust connection and quick installation.

With an isolation test voltage of 6kVRMS/50Hz/1min, the transducer complies with the European EN50155 and EN50124-1 traction standards (insulation levels, creepage and clearance distances). All materials used satisfy UL94-V0 and comply with the smoke and fire classification requirements for the traction industry (NFF 16101 and 16102). The LAC 300-S is CE marked and is supplied with a five-year warranty, as are all LEM railway products.
