Multifunctional Digital Electricity Power Instrument Multifunction AMP Energy Meter Voltmeter¹

Product Description Chapter 1. General introductionOn the basis of the conventional multifunctional network power instrument, it is added the measuring and display functions of the demand value, the maximum and minimum value, and the average value. It is displayed by 5-row 4-digit LED. The instrument can also be installed by different function modules to support the analog quantity, higher or lower alarm, and RS485 communication function.Chapter 2.Model and definitionChapter 3.General parameters Technical ParametersIndexInputNetwork 3-phase 3-wire, 3-phase 4-wireVoltageRated ValueAC 100V, 400VOverloadConsistent: 1.2 timesInstantaneous: 2 times/30sConsumption< 0.5 VA(each phase)Impedance> 500 kΩCurrentRated ValueAC 1A or 5AOverloadConsistent: 1.2 timesInstantaneous: 2 times/30sImpedance< 20 mΩ (each phase)Frequency45 ~ 65HzOutputElectric EnergyOutput mode2-channel open-collector optical coupling pulse outputPulse constantActive 10000imp/kwhReactive 10000imp/kvarhCommunicationOutput modeRS485ProtocolMODBUS_RTUAnalog QuantityChannel quantity2 ~ 4 channelsOutput model0 ~ 20mA, 4 ~ 20mA programmableLoad ability≤ 300ΩSwitching ValueChannel quantity2 ~ 4 channelsOutput modeNormally open relay contact outputContract capabilityAC 250V/1A (Resistance load)Switching value input4 - channel passive dry contact input modelMeasuring AccuracyVoltage, Currentclass 0.2Powerclass 0.5Frequency± 0.05 HzPower Factor± 0.01 PFActive electric energyclass 0.5Reactive electric energyclass 2.0Power SupplyScopeAC/DC 85 ~ 264V 50/60Hz AC220V ± 10%Power consumption< 5VAEnvironmentTemperatureOperation: -10 ~ 50oCStorage: -25 ~ 70oCHumidity≤ 85% RH, free of wet and gas corruptionChapter 4.
