AEMC Instruments 2153.52 - Data Logger Model L411 1-CH, TRMS, w/LCD, 3000 AAC

The AEMC® Data Logger Model L411 is a single-channel, True RMS AC current logger with an integrated MiniFlex® flexible Rogowski sensor rated up to 3,600 AAC. Think of it as the logging version of the 4000D Digital FlexProbe® — same flexible sensor convenience, now with configurable recording modes for extended field deployments.

Where the L411 stands apart is in its 1-second trend resolution. Every second, a TRMS measurement is captured and stored — the same data density you'd expect from a power quality analyzer. That 1s data is fully accessible through the DataView® Control Panel for analysis, charting, and reporting. For load profiling or demand audits, that matters.

The instrument runs on 3x AA alkaline batteries or continuous USB power — plug into a panel's USB outlet or wall adapter for uninterrupted operation with no recording gaps. Data is stored on an 8 GB micro-SD card supporting up to 200 recording sessions, transferable via USB or Wi-Fi.
