LEM Unveils Compact Current Transducer for 400 ARMS
Closed-loop current transducer offers high performance and compact size
Key points:
o Meets key industrial standards
o Small size coupled with nominal current measurement up to 400 ARMS
o Closed-loop, Hall-effect technology
GENEVA, Switzerland and MILWAUKEE, WI (February 28, 2007) - LEM S.A., the world's leading manufacturer of isolated current and voltage measurement components, has introduced the LA 306-S, a panel-mounted current transducer for the measurement of currents up to 400 ARMS (@ +70°C or 158°F) or 300 ARMS (@ +85°C or 185°F). The unit offers the high performance of a closed-loop current transducer at a very competitive price.
The new transducer is only 2.2 inches (56mm) high. It features a wide maximum bandwidth of DC to 50kHz and an overall accuracy of better than 0.7% at the primary nominal RMS current. Typical linearity error is ±0.1% at nominal current and the maximum offset temperature drift is 500 microamps from -40 to +85°C (-40 to 185°F). 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 0.51 x 1.18 inches (13 x 30mm). Specified with 2000 turns as standard, it is also available with 5000, 4000 or 3000 turns on request. A Molex 5045 plug is offered as standard for the secondary connections, to allow quick installation. A Molex series 70543 connector can be specified for a more robust connection.
With an isolation test voltage of 6kVRMS/50Hz/1min, the transducer complies with the EN50178 industrial standard. All materials used satisfy UL94-V0. The LA 306-S is CE marked and is supplied with a five-year warranty, as are all LEM industrial products.
