2100 can be widely used in electric power, post and telecommunications, oil, coal, metallurgy, railway, municipal, intelligent building, department of electrical devices, automatic control and scheduling system.
A. The functions and features
W measurement function is much, high precision
2100 is so powerful that it set a power transmitter, digital watt-hour meter, digital display table, data collector, log analyzer, RTU and so on some or all of the function.Measurement features include: a three phase four wire circuits, or any other wire/all phase line voltage (V), current (I), power (P, Q, S), power (Wh, Qh), power factor (COS), frequency (F) and zero sequence current (I0), etc.
When used as a display instrument can replace: three-phase current meter, three-phase voltage meter, three-phase apparent power table, three-phase active power meter, three-phase reactive power meter, three-phase active power factor meter, three-phase watt-hour meter, three-phase reactive watt-hour meter, frequency table, zero sequence current meter, etc.
Used for data collection in the automation system can replace: three phase current transmitter, three-phase voltage transducer, three-phase apparent power transmitter, three-phase active power transmitter, three-phase reactive power transducer, transmitter three-phase power factor, frequency, transmitter, zero sequence current transducer, etc. As well as the data acquisition module, RTU and so on.
As electrical energy meters can replace: active three-phase watt-hour meter, three-phase reactive watt-hour meter, etc.
Instrument module with high accuracy high stability (A/D) conversion device, power, electrical degrees of accuracy can reach 0.5, other parameters can be up to 0.2 on the Richter scale are unlikely.
W three remote and automatic control
2100 with her) (empty nodes remote communication input, three road relay (every road are often opened normally closed double contact) remote control output, combined with remote sensing and communication function of complete three remote function.Three road relay can also be set by the user for the automatic export control, such as over current, under voltage, under the condition of equal export relay action, etc.
W display in both English and Chinese
2100 adopts LCD large-screen LCD display, Chinese and English two sets of interface convertible, very suitable for China's national conditions.Display using the eyes feel more natural and comfortable blue backlight, embodies the concept of humanistic care.At the same time it can display up to four parameters, and can be set by manual or automatic, to read more than 30 parameters in sequence.
W standard specifications, easy networking
2100 in order to meet the future environment of the measuring instrument, equipped with RS - 485 and RS - 232 - c serial port, to allow local area network connection open structure.
Applying Modbus (RTU and ASCII mode) communication agreement, through the software running on a PC or data acquisition system, can provide a for factories, power plants, industrial or building services is simple and practical power management solution.
W automatic steady zero
With automatic calibration zero, to overcome the zero drift with time and temperature.All parameters can be zero free to move, improve the overall measurement precision of the instrument, improve the overall stability of the system, simplify the calibration process.
W a wide dynamic input range
2100 adopts automatic range switching technology, provide 5 ~ 120 v / 600 v input voltage range, 0 ~ 1 a / 5 a current input range, can automatically apply to all kinds of measurement system, without any adjustment of hardware and software.
W the internal real time clock (RTC)
2100 to provide internal RTC (real time clock), precise time record system.
W programmable state setting
2100 allows users to its working status "measurement system choice" and "CT, PT than" and "content", "communication", "clock", "energy accumulation reset" and "automatic control relay export conditions" to change Settings.
W memory
2100 when power off, can remember all of the current work status, or the set value, energy accumulation value, time, PT variable than, than CT.
W multiple connection mode
Applicable to a variety of connection mode: three phase four wire, three phase four wire balance load, three-phase three-wire and three-phase three-wire balance load, three line a phase 2 line and a phase.
W digital setting
All parameters using digital calibration, automatic control under special calibration debugging software, reduces the human factors caused by deviation.Abandoned the conventional using potentiometer simulation method, simplified the hardware circuit and improve the reliability and stability of the machine.
W the automatic fault diagnosis
With functions of automatic fault judgment, and will be showed on the screen or through the serial port output.
W electromagnetic interference resistance ability
Improve the electromagnetic compatibility design, with a strong ability to resist electromagnetic interference, IEC61000-4 standard, suitable for use in the complex environment of strong electromagnetic interference.
W convenient installation
2100 powerful features make the complexity of the system installation, wiring and material costs are lower.
The disk installation, overall dimensions accord with standard of Mosaic screen hole (hole size is 175 x 125 ㎜), ease of installation.
