Overview

The Eagle 120 is a complete ten function plug-in receptacle power quality analyzer that monitors two channels voltage and one channel of current in single-phase applications. When plugged into a standard 120V receptacle, it continuously detects and monitors sags, swells, flicker, RMS voltage, current, power factor, and harmonics. Additionally, the Eagle 120 captures waveforms from custom-triggered events. Power quality measurements are downloaded via USB cable.
