Total active energy kWh measure2. APP can read kWh , R.M.S current , voltage , active power3. LCD display, Real-time display of Voltage, Current, Active Power, reactive Power, power factory ,frequence, total Energy kWh4. Power Supply: 110V+110V+N, Please noted this meter forBrazi, USA. 2 phase 3 wires.5.MAX Current: 100AClamp CT6. Pulse Frequency: 1000imp/kWh7. 35mm Din Rail install8. Active energy accurate isclass 1 , IEC62053-21Push the button last more than 10s , the WIFI led will flash quickly , then use APP to operationbear 400V /hour not damageNote:This meter Only supports 2.4G Wireless Network, NOT for 5GThe meter is designed to measure single phase three wire AC active energy and variable parameter like residential, utility and industrial application in South America or North America. It can remote read from WIFI communication . It is a long life meter with the advantage of high stability, high over load capability, low power loss and small volume.Basic FunctionLCD display, button for LCD display step by stepBi-directional total active energy, reverse active energy measure in the total energyThe meter also display real conjunction phase voltage, conjunction phase active power, L1 line current, frequencyhistory active energy consumption tracking by APPcheck the real conjunction phase voltage, conjunction phase active power, L1 line current by APPClamp CT connection , easy for installationPulse LED indicates working of meterEnergy data can store in memory chip more than 15 years after power offActive energy will keep in meter memory chip when WIFI connect failed . it will not lose and will upgrade after WIFI connection again18mm width only 1 pole MCB dimension , 35mm din rail installationTechnical DataRate voltage AC90300V(L1-L2)110/220V (L1-N=110V L2-N=110V L1-L2=220V)Rate Current / Frequency10(100)A /50Hz or 60Hz10%Also can special order 100A or bigger clamp CTWIFI802.11b/g/nConnection modeIndirect typeAccuracy class1%Power consumption<2W/10VAStart current0.004Ib40mAAC voltage withstand4000V/25mA for60sOver current withstand30Imax for 0.01sIP gradeIP20Executive standardIEC62053-21Work temperature-2570Pulse outputPassive pulse, 805 msWire connection
