    Your PQube records events, trends, and statistics by monitoring your AC mains voltages. It also measures two analog input channels for additional signals (for example, the output of a power supply), a digital input channel, an output relay, and a full color display. Your PQube records all information to a standard SD memory card.

    Samsung Power Vaccine, ITIC, CBEMA, MIL-STD 704E, and MIL-STD 1399. These standards define ride-through curves based on the depth and duration of voltage dips. When the voltage dips below the ride-through curve, your PQube will trigger a Major Dip event. You can specify which standard to use in your Setup.ini file.
