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 equal 10kWh, the display unit is kWh, for example: 9999.99kWh Power: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 equal 1000W, only integers are displayed, for example: 1000W Voltage: 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: 0.1W 1.3.5 Measurement accuracy: 0.5% 1.4 Power factor 1.4.1 Measurement range: 0.00 ~ 1.00 1.4.2 Resolution: 0.01 1.4.3 Measurement accuracy: 1% 1.5 frequency 1.5.1 Measurement range: 45Hz ~ 65Hz 1.5.2 Resolution: 0.1Hz 1.5.3 Measurement accuracy: 0.5% 1.6 Active energy 1.6.1 Measuring range: 0 ~ 9999.99kWh 1.6.2 Resolution: 1Wh 1.6.3 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 alarm communication interface:RS485 interface.2 other instructions communication interface power supply (+5 V), current output capability is 100mA 2.2 Working temperature -20'C ~ + 60'C Brand Name: : Electrical Rated Voltage: 220V Max Operating Current: 100A - 119A Power Supply: AC Model Number: PZEM-016 Output Voltage: 80-260V Phase: Single Phase Display Type: Analog and Digital Operating Temperature: -10-60degree Measuring Energy Range: 0-9999.99Kwh Accuracy Class: 0.5grade communication port: RS485 protocol: Modbus-RTU current range: 0-100A colour:black Material:plastic size: 90*60.5*23mm Package Contents: 1 * Communication Box 1 * Open and Close CT (100A) 1 * USB to 485 Module Only 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. The measurement allowed error is +/- 1-3cm.
