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

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.

The L400 Series delivers the unattended, high-resolution data that turns guesswork into answers.
