Product Description Intelligent communication multi-channel energy meter 1.Product profileThe intelligent communication multi-channel energy meter is a new type of power monitoring and control energy meter that integrates measurement and recording, energy measurement, alarm output, and network communication functions. This electric energy meter can measure multiple grid parameters such as voltage, current, power, and residual current; Capable of configuring independent RS485 communication interface and 4G dual-mode communication, supporting MQTT communication protocol. It can achieve the monitoring of the operation status of 4 incoming and outgoing lines and branches, as well as the indication of fault status. 2.Technical indicatorsperformance parameterPerformance indexaccuracy class Voltage: ≤ 0.5%; Current: ≤ 0.5%; Active power: ≤ 0.5%; Reactive power: ≤ 1%; Power factor: ≤ 0.5%; Apparent workRate: ≤ 1.0%; Electricity quantity: ≤ 0.5%; Frequency: ≤± 0.02Hzdisplay mode OLED LCD screenConnection mode Three-phase four-wire/three-phase three-wireinput voltagerated voltageAC220Vfrequency range45~65HZmeasuring range154V~286Vincoming currentrated currentThe rated current is 100mA AC 300A/100mA. frequency range45~65HZmeasuring range10A~300Aworking power supplyrated voltageAC 220V (allowable deviation -20%~+20%)Power consumptionNot more than 3Wcommunication interfaceInterface formRS485,4G moduleprotocolModbusRTU,MQTTenvironmental conditionsAmbient temperature and humidityTemperature range:-40 ~+70oCMaximum temperature change rate: 1.0oC/ minRelative humidity: 10 ~ 100%Maximum absolute humidity: 35g/moperational environmentThere is no explosion danger, corrosive gas and conductive dust, serious mold and violent vibration shock source.storage temperature -40oC~80oCClock accuracyDaily error≤0.5 seconds/day, supporting communication timing.3.Selection specificationsfunctional moduleserial numberFunction pointFunction point descriptionIntelligent AC multi-channel watt-hour meterReal-time measurement1phase voltagePhase voltage: Ua, Ub, Uc√2line voltageLine voltage: Uab, Ubc, Uca√3Voltage sequence componentVoltage sequence components: U1, U2, U0√4phase currentPhase current: Ia, Ib, Ic√6active powerActive power: Pa, Pb, Pc, p.√7wattless powerReactive power: Qa, Qb, Qc and Q.√8apparent powerApparent power: Sa, Sb, Sc, s√9Power factorPower factor: Pfa, Pfb, Pfc, Pf√10phase positionVoltage/current: ∠Ua, ∠Ub, ∠Uc, ∠Ia, ∠Ib, ∠Ic√11frequencySystem frequency: f√Electricity measurement12Active powerSplit-phase and combined-phase bidirectional active energy√13Reactive powerSplit-phase and combined-phase bidirectional reactive power√14Apparent electric degreeSplit-phase and close-phase are in electric energy.√freeze15Minute freezingFreeze once at 15: 00 on the hour, with a maximum of 5,000 frozen items.√16Daily freezingFreeze once at 0 o'clock, with a maximum of 1000 frozen items.√17Monthly freezingFreeze once a month, with a maximum of 24 freezes.√Power quality18Harmonic contentThe harmonic content of three-phase voltage and current is 2~31 times.√19Harmonic distortion rateTotal, odd and even harmonic distortion rate√20imbalance/ loss of balanceUnbalanced voltage and current√incident record21SOE recordIt has 500 SOE recording functions, including alarm power failure, etc., with time scale recording.√22Maximum recordThe maximum and minimum values of relevant parameters (voltage, current, active power, reactive power, apparent power, power factor, frequency and demand) can be counted in real time, and recorded with time scales.○clock23clockAccurate clock with hardware√communication interface24RS485 communicationStandard 1 RS485 communication, supporting MODBUS-RTU protocol; Support online upgrade program through RS485 interface.√254G communicationSupport MQTT protocol√Current transformer26External current transformerBranch 300A~100mA transformer√Note: "√" marks this function as standard, and "○" indicates that this function is optional. 4.Product installation and schematic diagram5.About our service * We could provide 7* 24-hour phone call after-sales service. * We provide a 2-year guarantee time and will change the meter for you within 1 year if there's something wrong with the product.
