Two independent current probe terminals let this dual-channel AC current data logger record both circuits at once, comparing feeders, phases, or upstream and downstream loads in one session. Sensor auto-detection spans the full PEL and PowerPad probe family, from 10 mA control circuits up to 25,000 A AC main feeders.
AEMC Instruments L412 Offers
Part of the AEMC L400 Series, the Model L412 extends the family’s 1-second logging to two independent channels, so a single instrument can document two circuits at once. It accepts a wide range of AEMC PEL and PowerPad current sensors, letting one logger cover everything from low-level control wiring to high-current main feeders depending on the probe fitted. A built-in web server and Wi-Fi provide browser-based monitoring and setup on site, with DataViewSync™ for secure remote access over any internet connection. All recordings export to the free DataView® software for side-by-side analysis and reporting across both channels.
