Power quality analyzersQNA 412Power quality analyzer that measuresvoltages and currentsCharacteristicsPower circuitDescriptionQNA 412 is a state-of-the-art power qualityanalyzer certified as a class A device, in compliancewith the IEC-61000-4-30 Standard.It takes measurements in compliance withthe international standard. In addition to theanalysis of the variables related to the qualityof supply (voltage, flicker, harmonics, events,etc.), it also acts as a network analyzer andredundant counter, since it can be usedto analyse the current signals, power consumed(active and reactive), the power factorand active and reactive energy consumed orgenerated with an accuracy of 0.2S, as in thecase of the high-precision energy meters.Application}}Supervise the optimum operation of electricinstallations and transformers. The LV connectionenables the supervision of the saturationof the power transformer and the reactiveenergy consumed in each installation.}}Detection and instantaneous recording ofall events (in compliance with the IEC Standard)detected in the measurement point. Itcan be used to detect the origin of events toimplement the necessary actions and carryout the preventive maintenance actions,in order to optimize the performance of theinstallation, thus increasing the company'sproductivity.}}It can work as a redundant counter tocheck the energy charged by the company.The unit is fully sealable, so that it can not betampered with.Power supply rangeConsumptionFrequencyAuxiliary power circuitBatteryAutonomyVoltage measurement circuitNominal voltageOther voltagesFrequencySampling frequencyConsumption of the voltage per phase circuitCurrent measurement circuitMeasurement marginConsumption of the circuit, current per phaseMaximum sampling frequencyEnergy meter, maximum value100 - 400 Vac (± 30 %) / 90 - 730 Vdc16 V·A / 8 W50 - 60 Hz (QNA 412-T type, only 50 Hz)Ni 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·A.../5 (6) A (input with galvanic insulation).../1 (1.2) A (input with galvanicinsulation).../2 V.../ITF-EXTERIOR0.01 V·A14.130 kHz1 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-232, EthernetData memorySize4 MBSetupRotary (FIFO)Ambient conditionsUsage temperature 0 ºC ... +50 ºCStorage temperature -20 ºC ... + 70 ºCBuild featuresEnclosure In compliance with DIN 43859Differential IP 51Dimensions327 x 176 x 96 mmWeight2.3 kgSafetyEN-61010-1 category III 600 VQ2-14
