General introduction:
DTSD342-5D/5Z/5N DIN rail mount power monitor (DIN35mm rail installation) 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. In addition, the monitor possesses the function of 2~50 times harmonic analysis, calculation of a number of electric energy quality parameters, measurement of active and reactive electric energy as well as multi-rate electric energy and multi-rate demand measuring.

RS-485 communication interface is configured which supports MODBUS-RTU and DL/T645 dual communication protocol. Switch input and output function can also 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/T17215.321-2008 static reactive electric energy meter (class 1 and class 2).
4. GB/T17215.323-2008 static reactive electric energy meter (class 2 and class 3).
5. DL/T 614-2007 multifunctional electric energy meter.
6. DL/T 645-2007 communication protocol of multifunctional electric energy meter.
7. Modbus-RTU.

Main features
1.Adopt high-precision sampling and measuring unit as well as high-speed MCU data processing unit, achieving high precision, wide range and accurate measurement as well as fast data analysis.
2. Multi-line wide viewing angle LCD display is used to show richer contents.
3. The LCD display is equipped with white backlight to meet the requirement of consulting data in dark environment.
4. Nonvolatile memory is adopted to store all kinds of data, which can save data for a long time without losing data due to power failure.
5. With the high-precision temperature-compensation clock chip, the accuracy of the clock is guaranteed in the working temperature range.
6. Support RS-485 communication port and industrial standard communication protocol, convenient and flexible for network construction.

Main funcitons
1. Measurement of single phase voltage and current, metering of positive and negative active electric energy, identification and indication of power direction.
2. Optional time-sharing multi-rate electric energy metering function, through the upper computer the time table and rate parameters can be set.
3. With one channel RS485 communication interface, MODBUS-RTU protocol and DL/T645 protocol are optional.
4. With one channel active electric energy pulse output, 2 channel of switch input or output is optional.
5. Current circuit under 100A can get direct access to our monitor; current circuit above 100A need external current transformer, connecting by secondary line.
6. Voltage signal power supply, no need for auxiliary power supply.
