The PQ3K and PQ5K are cost effective meters that combine general purpose PQ detection (with waveform recording) and full 4 quadrant energy monitoring in one instrument. Wide-ranging applications include utility, facility, manufacturing, petrochemical, mission critical and more.
The PQ3K is housed in a 144mm x 144mm panel mounted enclosure that includes a high-resolution color TFT display.
The PQ5K is housed in a DIN mounted enclosure with an optional high resolution TFT color display.
Both are compliant with IEC 61000-4-30 Edition 3 Class A with a certification from an independent laboratory for trustworthy PQ measurements. These instruments detect and can record waveforms for sags/dips, swells, interruptions, as well as recording flicker, harmonics, RVC and more, all in parallel with complete energy metering capabilities. Digital I/O provides the ability to read alarms along with internal logic control to generate state/condition-based alarms. IEC 61850, Modbus and Profinet are available for remote communications with 3rd party SCADA and other monitoring systems.
