SD20M series are the single phase multifunctional energy meter to measure and analyze the most important electrical parameters, including voltage, current, four-quadrant power parameters, power factor, and etc. And it can also read a variety of energy parameters, involving bidirectional active and reactive energy, four-quadrant energy, monthly and daily energy consumption statistics, and so on.
The SD20M series have RS485 communication interface with highest baudrate 38400bps, supporting Modbus or DLT645 protocol for remote reading.
At the same time, the large-screen LCD and touch buttons help users to view and set various measurement parameters on site.
Password protection function is added to greatly improve the data security.
