AC Single Phase Watt Energy Meter RS485 Modbus 220V 100A Voltage Current Frequency Power factor Kwh Meter With Split CT&USB, This module is mainly used for measuring AC voltage, current, active power, frequency, power 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: 9999.99kWhPower:The AC voltage passes through the switching power supply to provide two isolated outputs. One way is to provide 3.3V 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: 999.9W ,When the data is greater than equal 1000W, only integers are displayed, for example: 1000WVoltage: Measurement range: 80 ~ 260V, Resolution: 0.1V , Measurement accuracy: 0.5% , Current, Measuring range: 0 ~ 100A , Initial measurement current: 0.02A, Resolution: 0.001A, Measurement accuracy: 0.5%, Active power, Measuring range: 0 ~ 23kW, Initial measurement power: 0.4W, resolution: 0.1W1.3.5 Measurement accuracy: 0.5%1.4 Power factor1.4.1 Measurement range: 0.00 ~ 1.001.4.2 Resolution: 0.011.4.3 Measurement accuracy: 1%1.5 frequency1.5.1 Measurement range: 45Hz ~ 65Hz1.5.2 Resolution: 0.1Hz1.5.3 Measurement accuracy: 0.5%1.6 Active energy1.6.1 Measuring range: 0 ~ 9999.99kWh1.6.2 Resolution: 1Wh1.6.3 Measurement accuracy: 0.5%1.6.5 Reset energy: Use software to reset.Power failure alarm:Can set the active power threshold, when the measured active power exceeds the threshold, you can alarmcommunication interface:RS485 interface.2 other instructionscommunication interface power supply (+5 V), current output capability is 100mA2.2 Working temperature-20'C ~ + 60'CBrand Name: DIY Supplies: ElectricalRated Voltage: 220VMax Operating Current: 100A - 119APower Supply: ACModel Number: PZEM-016Output Voltage: 80-260VPhase: Single PhaseDisplay Type: Analog and DigitalOperating Temperature: -10-60degreeMeasuring Energy Range: 0-9999.99KwhAccuracy Class: 0.5gradecommunication port: RS485protocol: Modbus-RTUcurrent range: 0-100Acolour:blackMaterial:plasticsize: 90*60.5*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.
