3.1 active power measurement display range: 0 ~ **9W ~ **9kW ~ ***9MW (unit automatically switch status indicator)
3.1 Reactive power measurement display range: 0 of ~ **9var to **9kvar to ***9Mvar (by the state indicator automatically switches)
3.2 Measurement Accuracy: ± 0.5% FS ± 1 word (active), ± 1.0% FS ± 1 word (reactive)
3.3 Rated voltage: AC**0V, **0V, **0V (transformer ratio is free to set)
3.4 Rated current: AC 1A or 5A (transformer ratio is free to set)
3.5 signal frequency range: *5.*0 ~ *5.*0Hz
3.6 The voltage circuit power consumption: <1VA
3.7 The current circuit power consumption: <0.5VA
3.8 Resolution: up to 1W, automatic decimal point shift
3.9 Sampling rate: 3 times / s
3.*0 overflow indication: display character "HHHH"
3.*1 polarity indication: to display the reverse power the negative signal automatically display "-"

3.*2 Auxiliary power: AC / DC *5 ~ **0V
3.*3 Auxiliary power consumption: <3VA
3.*4 Alarm output: upper and lower alarm the same relay contact output, contact capacity is AC**0V/2A DC*0V/2A.
3.*5 Transmitting output: freely set DC0 ~ *0mA, 0 ~ *0mA or 4 ~~ *0mA Accuracy ± 0.5% FS, and electrical isolation between the signal and auxiliary power
3.*6 Transmitting output load resistance: ≤ **0Ω
3.*7 Transmitting output accuracy: ± 0.5% FS (active), ± 1.0% FS (reactive)
3.*8 upper and lower alarm, corresponding to the transmission output shows the value of setting range: ****9 ~ 0 ~ ***9
3.*9 Communication interface: RS**5 serial communication using MODBUS_RTU communication protocol
3.*0 Address Setting range: 0 to **0
3.*1 Communication baud rate: ***0bit / s, ***0bit / s, ***0bit / s, ***0bit / s optional
3.*2 Working environment: temperature **0 to *0 ° C, humidity ≤ *5% RH, non-corrosive occasions

Functional modules can be added to achieve the special features:

Add one alarm plus **0 yuan

Plus all the way to **5 plus *0 yuan

3 plus all the way transmission plus $ *0.
