The Purpose of Ai205
Powerful Intelligent Power Meter
Ai205 Series Intelligent power meter was designed by used of latest
microprocessor and digital signal process technology. Electric power parameters,
energy and demands metering, power quality monitoring, remote control, over
range alarming, statistics and records, all these functions are only in one pocket-
size unit. There are also alarm on over/under Voltage, Current,Power, Power
Factor, Frequency, Unbalance Factors or Demands and Pulse Output based on
Energy or Reactive Energy in Ai205. Switch status monitoring is possible by
using the 4 digit inputs. It combines high accuracy measurement with intelligent
multifunction and simple HMI interface.
Idea Choice for Electric Automation SCADA System
Ai205 can be used to replace all traditional electric meters. It also can be
used as Remote Terminal Unit (RTU) for monitoring and controlling in a SCADA
system. All the measured data is available via digital RS485 communication ports
running the MobusTM protocol.
Energy Management
Ai205 can measure double directions four quadrants Kwh and Kvarh with
accuracy up to 0.5%. It can provide high standard energy data and energy demand
data. All these data is important for statistics of each line feeder and total.
Remote Power Control
The main function of Ai205 is measurement, but it has also got some flexible
I/O functions. This made the meter can be used as distributed RTU (metering,
monitoring, remote controlling in one unit).

Power Quality Analysis
With the powerful digital signal processing ability the Ai205 intelligent power
meter can be used as an online power quality analysis instrument. It can
simultaneously and continuously give out the analysis results such as THD of
voltage and current, harmonics up to 31st and unbalance factor of voltage and
current, etc. The main function of Ai205 are listed in table1.1

The Function of Ai205
Multifunction, High Accuracy
Ai205 Series Intelligent power meter was designed by use of latest
microprocessor and digital signal processing technology. Electric power
parameters metering, energy and demand recording, power quality monitoring,
remote controlling, over range alarming, statistics and records, all these functions
are only in one pocket-size unit. There are also basic alarm on over/under
Current, Voltage, Power, Power Factor, Frequency, Unbalance Factors or
Demands and Pulse Output based on Energy or Reactive Energy in Ai205. Status
monitoring is possible using the 4 digital inputs. It combines high accuracy
measurement with intelligent multifunction and friendly HMI interface.
Accuracy of Voltage and Current is 0.2%
Accuracy of Power and Energy is 0.5%
Small Size and Easy Installation
With the size of DIN96 96 and 55mm depth after mounting, the Ai205 can
be installed in a small cabin. The clips are used for easy installation and remove.
Easy to Use
By using of large screen high density LCD, the display of Ai205 is easy to
read and use. All the setting parameters can be access by using panel keys or
communication port. The setting parameters are protected in EEprom, which will
maintain its content after the meter is power off. With the backlight of the LCD,

the display can be easily read in the dim environment. The back light “on”time is
selectable.
Multiple Wiring Modes
In either high voltage or low voltage or three phase three wire or three phase
four wire or single phase system, the Ai205 can be easily used.
Ai205 series
The Ai205 series have two kinds of product, the standard Ai205 and the
advanced Ai205. Both these two products have multiple choice of I/O. Advanced
Ai205 has the basic measuring function of Ai205. It also gets extra function as
harmonics analysis, Max/Min record and over/under limit alarming.
