The Allen Bradley LC500-S/SP7 is an efficient closed-loop Hall Effect current transducer that excels in delivering precise current measurements. Designed specifically for primary nominal RMS currents of 500 A, this device is capable of measuring currents between 0 and ±1200 A. Its weight is a manageable 0.75 lbs, making it convenient for integration into various systems.

This transducer features a secondary nominal RMS output of 125 mA, thanks to a turns ratio of 4000:1, which provides a significant scaling of measured currents for accurate monitoring. The device operates effectively within a supply voltage range of ±15 to ±24 V, consuming less than 35 mA at ±24 V.

In terms of performance, the LC500-S/SP7 excels with a measuring resistance spanning from 0 to 47 Ω. It maintains a total error margin of less than ±0.6% at its rated input, ensuring reliable data. Linearity errors are minimal, specifically under 0.1% at a temperature of 25 °C. Offset current at nominal input of zero is less than ±0.5 mA.

Finally, the transducer boasts a rapid response time, responding to 90% of the final output in under 1 microsecond, allowing it to adapt swiftly to variations in current. This makes the LC500-S/SP7 particularly suitable for demanding applications where quick and accurate current measurements are crucial.
