AK 200 B420L

Current Sensors Overview

The LEM AK 200 B420L is a panel-mount AC current transducer from the AKR series, designed for high isolation in noisy power environments. It features a selectable primary current rating of 100 A, 150 A, or 200 A and operates with a 150 V ac, 24 V dc supply. The unit has a 21.7 mm bore diameter and measures 89.7 mm in width, 30 mm in depth, and 21.7 mm in height. It supports frequencies from 10 Hz to 400 Hz and functions within a temperature range of -20°C to +50°C.

Current Sensors Procurement Notes

Verify the specific primary current selection (100 A, 150 A, or 200 A) required for your application, as this model offers configurable ratings. Confirm that the 21.7 mm bore diameter accommodates your conductor size. Ensure the operating environment stays within the specified -20°C to +50°C range and that the 150 V ac / 24 V dc supply voltage matches your system requirements before ordering.

Current Sensors Selection Notes

Select this component when high isolation is critical for safety in noisy environments. The AKR series is optimized for non-linear loads where standard sensors may fail. Choose based on the necessary primary current rating among the available options. Verify that the panel mount form factor fits your enclosure constraints and that the frequency range covers your operational needs up to 400 Hz.

Current Sensors Part Context

This part belongs to the LEM AKR-B420L series, which specializes in reliable AC current measurement. The series is engineered for robust performance in demanding industrial settings. It complements other LEM solutions like the LF series for DC/AC hybrid measurements and the HTA series for high-precision applications. The AKR line focuses on providing durable, isolated sensing for AC currents in complex power architectures.

Current Sensors Replacement Considerations

Direct substitutes include other models within the LEM AK-B420L family, such as the AK 100 B420L or AK 150 B420L, depending on the required primary current rating. Cross-series replacements like the AT20B420L may be considered if different packaging or interface specifications are acceptable, provided they meet the same isolation and current handling requirements.
