General introduction:
DTSD342-9 electric power distribution monitor integrates measurement and recording, electric energy metering, teleindication and telecontrol, large screen LCD display and network communication, which can measure voltage, current, power, power factor, frequency and other parameters of the grid. Besides, the monitor possesses the function of 2~50 times harmonic analysis, calculation of a number of electric energy quality parameters as well as measurement of active and reactive electric energy. RS-485 communication interface is configured which supports MODBUS-RTU and DL/T645 dual communication protocol. With switch input and output function, analog transmission output can be configured.

The monitor can be widely used in substation automation, industrial control and industrial automation system, energy management system, residential power monitoring and other occasions.

It complies with the following standards:
1. GB/T17215.301-2007 special requirements of multi-function electric energy meter.
2. GB/T17215.322-2008 static active electric energy meter (class 0.2S and class 0.5S).
3. GB/T17215.323-2008 static reactive electric energy meter (class 2 and class 3).
4. DL/T 614-2007 multifunctional electric energy meter.
5. DL/T 645-2007 communication protocol of multifunctional electric energy meter.
6. Modbus-RTU.
