Three-phase multi-function power meter is a kind of multi-function smart meter with programmable measurement, display, digital communication and electric energy pulse transmission output. It can complete electric quantity measurement, electric energy metering, data display, acquisition and transmission, and can be widely used in substation automation. , Power distribution automation, intelligent buildings, and internal electric energy measurement, management, and assessment of enterprises. The measurement accuracy is 0.5 grade, realizes the LED on-site display and remote RS-485 digital interface communication, and adopts the MODBUS-RTU communication protocol.
Requirements
When all the meters are used for the first time, please check the consistency of the parameters required in the power distribution system where the parameters of the meters are located. For example, for AC380V, 200A/5A lines, AC400V, 200A/5A meters need to be configured. The user can also reprogram the instrument according to actual needs. The same table, for 400A/5A lines, only need to modify the CT ratio "T.I" of the meter to 80. In general, the type parameter and factory setting parameters of the instrument are indicated on the label behind the instrument.
After configuring the meter correctly, perform the correct wiring of the meter according to the actual requirements, and perform the auxiliary power supply, input signal and output signal according to the operating instructions of the manual.
