Description
The AEMC® Data Logger Model L412 is a dual-channel RMS AC current logger with two universal current probe terminals — compatible with most AEMC® current sensors in the PEL and PowerPad family. Where the L411 gives you one flexible sensor built in, the L412 gives you two configurable channels and the flexibility to choose the right sensor for whatever you’re measuring — from 10 mA on a sensitive control circuit up to 25,000 A on a main feeder (using a ratio-configured MN193-BK).
Both channels record 1-second TRMS measurements simultaneously and independently. That 1s trend data — the same granularity as a PEL power analyzer — is fully accessible through the DataView® Control Panel for analysis, comparison, and reporting across both circuits in the same session.
Like the rest of the L400 Series, the L412 runs on its own built-in web server. Connect via Wi-Fi AP mode (its own broadcast network) or Station mode (your facility network), open a browser on any device, you’re live – no app, no software install, no laptop required on site. Remote access via DataViewSync™ extends that reach to anywhere with internet access.
Sensors are sold separately.
L1 and L2 — Independent & Simultaneous
Primary Current Input — Channel 1 — L1
Accepts any compatible CA current probe. Frequency measurement is available on Channel 1 only (45.00-65.00 Hz, 0.01 Hz resolution). The L1 input drives the frequency reference for the session.
Measurement range: 0.2% Inom — 120% Inom
Uncertainty: ±(1% R + 0.1% Inom)
Secondary Current Input — Channel 2 — L2
Logs independently from L1 with identical measurement specifications. If two sensors are connected, they must be the same model. If sensors don’t match, the OL indicator blinks as a warning. L2 does not measure frequency.
