AC Single Phase Watt Energy Meter RS485 Modbus 220V 100A Voltage Current Frequency factor Kwh Meter With Split CT&USB, This module is mainly used for measuring AC voltage, current, active , frequency, factor and active energy, the module is without display function, the data is read through the RS485 interface.Display Format:When the data is less than 10kWh, the display unit is Wh (1kWh = 1000Wh), for example: 9999Wh ,When the data is greater than equal 10kWh, the display unit is kWh, for example: 999999kWh:The AC voltage passes through the switching supply to provide two isolated outputs. One way is to provide 33V to the measurement system, and the other way is to provide 5V for the 485 communication circuit and external circuits.Display Format:When the data is less than 1000W, one decimal place is displayed, for example: 9999W ,When the data is greater than equal 1000W, only integers are displayed, for example: 1000WVoltage: Measurement range: 80 ~ 260V, Resolution: 01V , Measurement accuracy: 05% , Current, Measuring range: 0 ~ 100A , Initial measurement current: 002A, Resolution: 0001A, Measurement accuracy: 05%, Active , Measuring range: 0 ~ 23kW, Initial measurement : 04W, resolution: 01W135 Measurement accuracy: 05%14 factor141 Measurement range: 000 ~ 100142 Resolution: 001143 Measurement accuracy: 1%15 frequency151 Measurement range: 45Hz ~ 65Hz152 Resolution: 01Hz153 Measurement accuracy: 05%16 Active energy161 Measuring range: 0 ~ 999999kWh162 Resolution: 1Wh163 Measurement accuracy: 05%165 Reset energy: Use software to reset. failure alarm:Can set the active threshold, when the measured active exceeds the threshold, you can alarmcommunication interface:RS485 interface2 other instructionscommunication interface supply (+5 V), current output capability is 100mA22 Working temperature-20'C ~ + 60'CBrand Name: DIY Supplies: ElectricalRated Voltage: 220VMax Operating Current: 100A - 119A Supply: ACModel Number: PZEM-016Output Voltage: 80-260VPhase: Single PhaseDisplay Type: Analog and DigitalOperating Temperature: -10-60degreeMeasuring Energy Range: 0-999999KwhAccuracy Class: 05gradecommunication port: RS485protocol: Modbus-RTUcurrent range: 0-100Acolour:blackMaterial:plasticsize: 90*605*23mmPackage Contents:1 * Communication Box 1 * Open and Close CT (100A)1 * USB to 485 ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
