L461 is a 2-input, single-channel TRMS AC/DC voltage quality logger designed for distribution monitoring and solar PV applications. It supports voltage measurements up to 1,200V AC for AC circuits and up to 1,700V DC for DC systems, making it ideal for solar strings, battery banks, and DC bus rails. The logger features two direct inputs — COM and + — that connect easily to the included voltage leads and alligator clips. Its key advantage is 1-second TRMS trend logging, which provides detailed voltage quality analysis through the DataView® control panel. This high-resolution data helps identify voltage sags, swells, and fluctuations that longer-interval loggers may not capture. Ideal for solar PV verification, distribution auditing, and applications where voltage stability is critical, the L461 also includes a built-in web server for convenient remote access. Simply connect via Wi-Fi and open a web browser to view live data — no software, app, or laptop installation required on site.
