Multi-rate Multifunction Digital Panel Meter

GeneralZ Series Network Power Meters are used in persistent monitoring and controlling for power distribution system. It can measure all common electric parameters, active and reactive electric energy demand. They can control and over-limit alarm in distance with the functions of analog value transmitting output and calculating the maximum demands. DO output is used in over-limit alarming and long distance remote controlling. The limiting value of the alarming can be program controlled and configured. All the data can be read by RS-485 communication interface according to MODBUS Protocol and the switch value DI can be used for monitoring the state of the switch. Z series power meters integrate the high precision electric parameter measurement, smart electric power measurement with management and simple human-machine interface.Technical DataAccuracyUI 0.2 class,PQ 0.5 class,Active electric energy 0.5 class,Reactive electric energy 2 classDisplayProgrammable LCD or LED displayInput measurementNetworkThree Phase Three Line, Three Phase Four LineRated valueVoltageAC 100V400VCurrentAC 1A5AOverloadingContinuance1.2 times InstantaneousVoltage 2 times (10s),Current 10 times (5s)Power consumptionVoltage1VA(each phase) Current0.4VA(each phase)ImpedanceVoltage300kΩ Current20mΩFrequency50/60Hz±10%Electric energy measuringElectric energyActive and reactive electric energy measuringPower supplyWorking rangeACDC 80V270VPower consumption≤5VAOutput programmableAnalog value2 or 4 loops transmitting output420mA/020mADigital valueRS-485 Interface,MODBUS-RTU protocolPulse output2 electric energy pulse output,light coupler relaySwitch value input4 loops (2 loops) switch value input,dry node point mode (plase refer to the detail)Switch value output4 loops (2 loops) switch value output,light coupler relay (plase refer to the detail)Operation conditionAmbient temperature: -1055,relative humidity ≤93%,no corrosive gas,height above sea level≤2500mIsolation withstand voltageInput and power supply2kV,input and output 2kV, power supply and output1.5kVInsulation resistance≥100MΩ
