Power quality analyzersQNA500Modular power quality analyzerDescriptionFeaturesQNA500 is a modular power qualityanalyzer designed to measure and logthe main electrical parameters and thetransient disturbances. The measurementis taken as an RMS value by 5 ACvoltage inputs and 4 AC current inputs.(through current transformers I5 A).

By automating this information, theuser can display the most important informationwith just one click, in order to carryout the corresponding analysis.Measurement range0 ... 500 V p-n/ 0 ... 866 V p-pOther voltagesThrough the measuring transformersMaximum voltage of the1500 V ac(p-p)permanent measurementMaximum voltage of the1.2/50 μS (8/20 μS) 6 kVinstantaneous measurementFrequency42.5 ... 69 HzSampling frequency512 samples/cycleCurrent measurement (QNA500)Measurement range1 ... 120 % I n...
