Press Release Summary:
Model LAX 100-NP Closed Loop Hall-effect sensor measures currents up to 16.67, 25, 33.33, 50, or 100 ARMS, and multiple measurements is possible with single reference. CE marked unit is 16.35 mm high, and integrates with power modules in drive and inverter designs. It features maximum bandwidth of DC to 300 kHz and overall accuracy of ±0.91% at primary nominal rms current of 100 A. Typical linearity error is ±0.06% at 100 A and temperature drift is 200 microamps max from 0 to +70°C.
Original Press Release:
LEM Introduces Low-Profile, PCB-Mounted Transducer for Currents up to 100ARMS
Key points:
Configurable for different current ranges
Multiple measurements with single reference reduces cost
Only 16.35mm high
GENEVA, Switzerland and MILWAUKEE, WI (June 6, 2006) - LEM has introduced the LAX 100-NP, a miniature PCB-mounted transducer for the measurement of currents up to 100ARMS. This new Closed Loop Hall-effect sensor can be configured, by means of the primary connections on the PCB, to measure currents up to 16.67, 25, 33.33, 50 or 100ARMS. Its design simplifies integration with power modules in drive and inverter designs.
Because the same transducer can be used for different current ranges, ordering and stock-holding are simplified. Also, in systems where a number of different currents have to be measured, this can be achieved with a number of LAX 100-NPs but only a single reference, reducing cost even further.
This new transducer is only 16.35mm high. It features a wide maximum bandwidth of DC to 300kHz and an overall accuracy of better than ±0.91 percent at a primary nominal RMS current of 100A. Typical linearity error is ±0.06 percent at 100A and temperature drift is 200 microamps max from 0 to +70°C. The Closed Loop Hall-effect technology results in no insertion losses and a fast response time (few ms). The LAX 100-NP, CE marked, comes with a five-year warranty, conforms to the EN50178 standard and is suitable for industrial applications such as variable speed drives, UPS, SMPS, air conditioning and home appliances.
