Power quality analyzersQNA-PPortable power quality analyzerDescriptionCharacteristicsPortable electric power quality analyzer thatmeasures and records the data in compliancewith the class A IEC-61000-4-30 Standard.Specially designed for outdoor measurementsor in situations that require a highlyaccurate and very robust unit.The QNA-P enclosure has an IP 67 degree ofprotection, which guarantees its robustnessto strong impacts. The QNA-P analyzer hasbeen tailor-made with clips and it has a widerange of flexible (LV measurements) andrigid clips (LV and MV Measurements). Theinternal switches can be adapted to any typeof network (3/4 wires), with the use of its rigid(CP type) and flexible (C-FLEX type) clips.Application}}The QNA-P portable analyzer is highlyversatile and can combine rigid and flexiblenucleus clips. Its robustness makes it idealfor the intake of measurements in placessubject to severe weather conditions.}}The unit has been specially designed forthe execution of audits and revisions, since ithas been certified as Class A, in compliancewith the IEC-61000-4-30 Standard, so thatthe measurements taken can be used for anytype of verification; a pattern element is usedduring the intake process.}}The internal GSM type can also be usedto download the information remotely anddraft a report with the data, even before removingthe analyzer, which avoids the needof travelling to the installations.Power circuitPower supply rangeConsumptionFrequencyAuxiliary power circuitBatteryAutonomyVoltage measurement circuitNominal voltageOther voltagesFrequencySampling frequencyConsumption of the voltage per phase circuit100 - 240 Vac16 V·A / 8 W50 - 60 HzNi MHConfigurable, up to 9999 s of continuous operation3 x 500 / 866 Vac (for 4-wire connections)3 x 500 Vac (for 3-wire connections)Through the measurement transformers42.5 ... 69 Hz14.130 kHz0.3 V·ACurrent measurement circuitMeasurement marginDepending on the clipMaximum current1.2 I nMaximum sampling frequency14.130 kHzEnergy meter, maximum value1 999 999 kW·h (rotates)AccuracyVoltage 0.1 % U n(IEC-61000-4-30 class A)Current 0.1 % I n(IEC-61000-4-30 class A)EnergyClass 0.2S in accordance with EN-62053-22Unbalance ± 0.15 % (IEC-61000-4-30 class A)Flicker 5 % (IEC-61000-4-15, IEC-61000-4-30 class A)HarmonicsIEC-61000-4-7 class I, IEC-61000-4-30 class ACommunicationsRS-232 / RS-485, GPRS / GSM / RS-232Data memorySize4 MBSetupRotary (FIFO)Ambient conditionsUsage temperature -20 ºC ... +65 ºCBuild featuresEnclosureSealed enclosureDifferential IP 67Dimensions470 x 357 x 176 mmWeight6.7 kgSafetyEN-61010-1 category III 600 VQ2-17
