L411 Single-Channel AC Current Data Logger

Built for the Field. Designed to Last.

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 uninterreupted 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.

Why Choose Model L411?

1-second Trend Logging — Records 1-second TRMS measurements continuously — the same granularity as the PEL power analyzer. Full 1s trend data is available through the DataView^® Control Panel for detailed load profiling, demand analysis, and current quality review. Most data loggers in this class don't get close.

Browser-Based Control — No App Needed — The L411 runs a built-in web server. Connect via Wi-Fi and open any browser on your phone, tablet, or laptop — view live measurements, sync data and time, and configure or schedule recording. No software installation required. Walk up, connect, configure, walk away.

Wi-Fi AP Mode Its Own Network — In Access Point mode, the L411 broadcasts its own Wi-Fi network. Your phone connects directly — no router, no IT ticket, no site network needed. Perfect for panel rooms, mechanical spaces, or any location without existing connectivity. Switch to Station mode to join your facility network for remote access via DataViewSync^®
