DDS3102-P4 DIN Rail Mount Power Monitorr

General introduction:
DDS3102-P4 DIN rail mount power monitor is an electric power monitor integrated with measurement and recording, electric energy metering, LCD display and network communication, which can measure voltage, current, active power, power factor, frequency and other parameters of the grid, as well as meter positive and negative active electric energy and multi-rate electric energy.

In addition, our DIN rail mount power monitor possesses the function of freezing and load curve, overload tripping, as well as timing tripping and closing.

RS-485 communication interface and far infrared dual communication interface could be configured, supporting MODBUS-RTU and DL/T645(2007) dual communication protocol.

The monitor is widely applied to substation automation, industrial control and industrial automation system, energy management system, residential power monitoring, etc.

It complies with the following criteria:
1. GB/T17215.322-2008 static active electric energy meter (class 0.2S and class 0.5S).
2. GB/T17215.321-2008 static reactive electric energy meter (Class 1 and class 2).
3. DL/T 645-2007 communication protocol of multifunctional electric energy meter.
4. Modbus-RTU.

Main features
1. Our monitor adopts high-precision sampling and measuring unit as well as high-speed MCU data processing unit, which can realize high precision, wide range and accurate measurement as well as fast data analysis.
2. Wide viewing angle LCD display is adopted to show richer contents.
3. Equipped with white backlight, the LCD display can meet the requirement of consulting data in dark environment.
4. nonvolatile memory is used to store all kinds of data, which can save data for a long time without losing data due to power failure.
5. Support RS-485 communication interface, far infrared dual communication interface, and industrial standard communication protocol, which is 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 and one channel active electric energy pulse output, MODBUS-RTU protocol and DL/T645 protocol are optional.
4. Current circuit under 60A can get direct access to our monitor; current circuit above 60A need external current transformer, connecting by secondary line.
5. Voltage signal power supply, no need for auxiliary power supply.
6. 7-bit wide temperature range LCD display, data cycle display.
