AEMC® Instruments Expands Data Logger Lineup with New L400 Series Built for Hands-Off Monitoring

May 14, 2026

When something goes sideways in an electrical system, the question is never if the data was there. It’s whether anyone was around to catch it. AEMC’s new L400 Series Data Loggers — the L411, L412, and L461 — are built to be the ones watching, so you or your customers don’t have to. Each model is purpose-built for a specific monitoring challenge:

L411: Single-channel TRMS AC current logger with an integrated MiniFlex® Rogowski sensor rated up to 3000 AAC. Ideal for flexible installation around large or awkward conductors where rigid CTs won’t fit.

L412: Dual-channel TRMS AC current logger with two probe terminals compatible with AEMC PEL current probes and sensors. One logger, two circuits, full sensor flexibility.

L461: Two-input, single-channel TRMS AC/DC voltage quality logger rated 1000 V CAT IV and 1500 VDC CAT III. Engineered for distribution monitoring and solar PV applications, with 1-second voltage quality analysis built in.

KEY FEATURES

• 1-second Trend Logging: available through the DataView^® Control Panel
• Continuous USB power: eliminates battery life limitations for uninterrupted monitoring No dead batteries mid-study.
• Built-in web server (no app required): browser access to live data, configure recordings and time sync.
• Remote Access: with DataViewSync^™ extends the reach to anywhere in the world with internet access — perfect for fleet deployment.

APPLICATIONS
