Combined Power Quality and Energy Consumption Measurment

The PQ3K is a cost effective monitoring solution that combines general purpose PQ detection (with waveform recording) and 4 quadrant energy monitoring in one instrument. Wide-ranging applications include utility, facility, manufacturing, petro chemical, mission critical and more. The PQ3K is housed in a 144mm x 144mm panel mounted enclosure with a high resolution, color TFT display. The PQ3K is fully compliant with IEC 61000-4-30 Edition 3 Class A for trustworthy PQ measurements. It can detect and record waveforms for sags/dips, swells, interruptions, as well as recording flicker, harmonics and more, all in parallel with complete energy metering capabilities. Digital I/O provides the ability to read alarms and provide state/condition based monitoring and alarming. IEC 61850, Modbus and Profinet are available for remote communications with 3rd party SCADA and other monitoring systems.
