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^®

Choose Your Recording Strategy

NORMAL MODE

Continuous 1-Second Sampling

The insturment is never in standby. A True RMS measurement is taken and stored every second for the full duration of the recording session — the same operational model as a PEL power logger. Aggregated values are calculated fomr the complete 1s dataset, giving you the most accurate pciture of what happened on that circuit.

Best for: load profiling, demand studies, commissioning verification, and any application where you need the full 1s trend avail for review.

1s measurement interval — continuous, no sleep

EXTENDED MODE

Snapshot Measurements — Up to 10 Weeks

The instrument sleeps between recordings to conserve battery. A 1-second TRMS snapshot is taken at each preset interval (e.g., every 1 minute, every 15 minutes) and the instrument returns to sleep until the next interval. Only 4 snapshot measurments per aggregation period are stored — fewer data points, but dramatically longer battery life.

Best for: long-term trend monitoring, remote sites with infrequent access, and scenarios where battery replacement isn't practical

~10 weeks at 10/15 min aggregration

Application Use Cases

Feeder Load Trending

Monitor load current on a feeder circuit over time to identify peak demand periods and load trends. The 1-second resolution gives you the granularity to catch short-duration demand spikes that longer interval loggers miss — and the the full trend dataset in DataView^® to back it up. Identify demand spikes before they become problems.

Energy Auditing

Deploy across distribution panels, branch circuits, or individual feeders for days or weeks. Export to DataView^® for analysis and reporting. Extended mode stretches battery life to 10 weeks for long-term studies without site visits.

Commissioning & Verification

Verify new installations or retrofits are drawing expected current. The MiniFlex^® sensor installs in seconds without disconnecting the circuit — wrap it around, snap it closed, hit record. Two buttons. Done

Predictive Maintenance

Establish current baselines for critical motors, compressors, and HVAC equipment. Trend data over time to detect early signs of overload, mechanical wear, or insulation degradation before equipment fails.

Solar PV Monitoring

Monitor AC current output from solar inverters and generation equipment. Pair with the L461 voltage logger for a complete PV circuit picture — log both current and voltage simultaneously across the same system.

Remote Data Collection

Leave the L411 logging in a remote mechanical room. In AP mode, walk up and pull data from your phone browser. In Station mode, connect via DataViewSync^™ from anywhere with internet access — no return visit required.

Introducing the AEMC^® L400 Series Data Loggers!

These three dedicated loggers (L411, L412, and L461) are designed to help you log, analyze, and report current or voltage data from anywhere you have a connection.

With built-in Wi-Fi, USB connectivity, DataView^® compatibility, automatic time stamping, and long-term measurement storage, the L400 Series makes it easy to spot variations, track system performance, and troubeshoot issues over time.
