DDS102-P2 DIN Rail Mount Power Monitor
General introduction:
DDS3102-P2 DIN rail mount power monitor integrated with measurement and recording, electric energy metering, LCD display and network communication, 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.
The monitor equips RS-485 communication interface and far infrared dual communication interface supporting MODBUS-RTU and DL/T645-2007 dual communication protocol, which can be widely used in substation automation, industrial control and industrial automation system, energy management system, residential power monitoring, etc.
It conforms to the following standards:
1. GB/T17215.321-2008 static reactive electric energy meter (Class 1 and class 2).
2. DL/T 645-2007 communication protocol of multifunctional electric energy meter.
3. 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. 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. Configured with one channel RS485communication interface and one channel active electric energy pulse output, MODBUS-RTU protocol and DL/T645 protocol are optional.
3. Current circuit under 60A can get direct access to our monitor; current circuit above 60A need external current transformer, connecting by secondary line.
4. Voltage signal power supply, no need for auxiliary power supply.
5. 7-bit wide temperature range LCD display, data cycle display.
