Measuring both AC and DC, this voltage data logger covers electrical distribution and solar PV from a single instrument, reaching 1200 V AC and 1700 V DC across strings, battery banks, and DC bus rails. Its 1-second True RMS trend logging documents voltage sags, swells, and fluctuations at a resolution longer-interval loggers cannot match.

The AEMC L400 Series Model L461 is the only logger in the family that measures voltage, and the only one that handles DC. A switchable AC/DC front end and a wide measurement window suit it to both electrical distribution work and solar PV verification from a single instrument. A built-in web server with Wi-Fi delivers live readings and recording setup from any browser, while DataViewSync™ extends access to remote substations and switchgear over the internet. Recorded sessions open in the free DataView® software for charting and report generation.
