AM-690 Intelligent Power Meter
AM-690 Series Intelligent Power Meter has collected the functions of a comprehensive three-phase power measurement, accumulated energy, harmonic measurement, digital input/output, residual current fire monitoring a variety of network communication interface. And it is enhanced of four-quadrant energy metering, automatic meter reading period billing (TOU), demand statistics, Programmable limit alarm, recording of serial order (SOE), the output of electrical degrees pulse, analog input/output, temperature measurement and other functions. This meter is suitable for the measurement of voltage and current distortion caused by nonlinear loads and contains the high-order harmonic occasions, and data acquisition of intelligent power distribution system or business process automation system. Standardized communication interface unit is available in the PLC, DCS, SCADA systems, which can also be configured with the industry software (Intouch, Fix, King view, Likong, control, MCGS). Large-screen, high-definition LCD will be fully meet your visual requirements and elegant, bright backlit display will be easily access different measurement data under faint light. Humane method of operation can make the user mastered in a short period of time. Large window multi-line display mode will make the users reading a number of power parameters without having to touch the buttons. In order to facilitate and optimize the use of AM-690, the principle of the most practical plug-in modules is chosen. To increase functionality, just insert the module into the back of the meter.

Function Description
In order to meet the different needs of customers, with continuous innovative, AM-690 have the comprehensive functionality and measurement accuracy, the AM-90 series products are divided into four types:
• AM-690B (Basic) • AM-690T (timesharing electric degree type)
• AM-690F (quality-type) • AM-690Q (full-function type)
Note: In order to facilitate for the description, the product functionality is a basic description in this catalogue,and other models may not have some function. Please note that the reference to the content of the following table.
Functional detailed analysis
Basic measurement parameters:
Three-phase phase voltage, line current, and their average
Three-phase phase current, average current, neutral current
Four-quadrant measurement of each phase and total active power
Four quadrant measurement of each phase and the total reactive power

Real-time clock
△ measurement:
Way four quadrant energy measurement: active, reactive and apparent energy accumulated
Multifunction TOU: 4 time zone can be set for the rate of four kinds, each time zone can be divided into a maximum of eight periods
Energy monthly billing and automatic meter reading records, automatic backup on monthly energy data
Basic measurement parameters automatically record month energy data capabilities Overview
△ Demand Statistics:
There are a variety of statistical methods for demand Statistics . AM-690 used the sliding window demand method,which can measured active demand, the amount of reactive power demand and apparent power demand. The width of the sliding window can be set to be 1 to 60 minutes.The time of each sliding window is fixed at 1 minute. Demand clearing operation can be by panel operation or communication settings
△The most value statistics:
AM-690 can check the real-time statistics of related parameters (each phase current, active power, reactive power, apparent power), set the time interval (5 to 60 minutes) the maximum, minimum and average time update . These records are stored in the nonvolatile memory,and the data is not lost even without power. Most value clearing operation can be by panel operation or communication settings.
△Off-limit alarm:
Measurement parameters can be selected as monitoring object and the alarm type (high alarm and low lift / lift, lifted high / low alarm not lifted) and delay time can be set. When the the parameter is in alarm condition and exceeded the time limit, the alarm will be activated to trigger the output of D0 .
△ power quality parameters:
Harmonic distortion
2 to 31 times harmonic content, the odd harmonic distortion, even harmonic distortion rate of the three-phase voltage, current unbalance
Power quality should be conformed to the following standards:
Power quality power supply voltage deviation GB / T 12325-2008
