 Electronic 3-phase Multi-functional Meter Model DTSD846/DSSD846 |
|
This product supports multi-functional meters conforming to Standard T 614-2007 on Multi-functional Meters. Its main feactures lies in having no any
physical adjustment components, but signal digital operation, digital filtering, digital error correction, digital calibration, insensibility to temperature, and excellent
sensibility. twentyfold overload multiples, ability to record the power even under an extremely low load. Accurate measurement of voltage, current, power factor
and power, and can substitute the function of a number of indicating instruments and transmitters.
The basic functions include active power two-way, reactive quadrant four-tarriff data processing units, able to achieve indication of the maximum demand for
four-tarriff and other related functions.
After and RS485 interface is added, it's possible to read the data from the meter through negative control terminal or other data terminal devices to form into an
electric energy billing system; the communication protocol conforms to DL/T 645-2007.
Infrared Communication Protocol Conforming to Protocol DL/T 645-2007 
Data Processing Functions as Follows:
1. Electricity metering
2. Demand indication
