DDSF3333 single phase multi-rate energy meter is designed for measuring single phase active energy.
1. PRODUCTS INTRODUCTION:This single phase electronic energy meter was smart digital and was developed totally by our company, This products adopt ultra-low power large scale integrated circuit and very advanced SMT production technology, makes it have high Measurement precision, stable capability,high quality, excellent EMC performance. This meter have functions of : positive and negative active energy counting,energy consumption recording, event during working recording ( event such as Voltage,Current,power factor,load, demand,programming etc.) and Infrared communication and RS485 communication. The data of this watt-hour meter is easy to read by infrared of Hand hold device. Its performance meets all the demand of GB/T17215-2002 1 2 class static A.c watt-hour meter,GB/T17883-1999 0.2 & 0.5s static A.C active watt-hour meter, national standard and DL/T614-1997 Multi-rate watt-hour meter . The communication meet the demand of DL/T645-1997 Communication protocol of multi-rate watt-hour meter.Function1) Metering Function:A) Forward active energy ( positive + negative):a) Forward active total electricity quantityb) Four rate forward active electricity quantityB) Reverse active total electricity quantity2) Time and data :a) Clock:a) Second,minute,hour,week,day,month,yearb) Recognized automatically in leap yearc) Clock with compensationd) Broadcast time only one time one day, time range is 5 minutes/dayb) Rate:a) Four types of rate can be chosen during 24 hoursb) It can set up most ten time periods during 24 hoursc) It can divide most 12 season periods one yeard) It can chose four types of rate metere) It can program in weekendf) It can set up 10 public holidays
3) Event:a) Record ( accumulated time,occur times, the last occur time ).Power interruption.Communication ( no accumulated time ).Open terminal cover and recordb) Indication ( LCD Or LED ) :Power on ( LED always light , when there are pulse coming, the LED will be off in a minute, and state indication ) Open terminal cover and record ( event indication , resetautomatically after readingData from opening terminal cover ).Weak battery ( real-time indication when power on , it can keeporiginal state afterPower interruption ) .Electric larceny indication ( state indication )Reverse energy ( state indication ) CommunicationInfrared +RS485 communicationCommunication Content:Display:LCD:Read data.Program data ( protections as following ) :Manufacturer set up hardware protectio ( J4 ) :all programdata are not limited by code.Meter code:rate meter,cyclic display meter,Display mode setting,code,meter number,Consumer number,clock.Open terminal cover and record:Broadcast set up IDBroadcast calibration timeRead meter number automaticallyDisplay mode:Active current:may set up frequent display mode and awaken display mode1. Frequent display mode:cyclic display content ( cyclic period is five seconds ) , May set up cyclic display.2. Awaken display mode:when no display in the LCD, external magnetic filed can awaken cyclic displaycontent ( it will be closed LCD after five minutes ) No Active current:when no display in the LCD, externalmagnetic field can awaken cyclic display content.Cyclic display content:please check addendum 1.Whensystem mistake, insert 00 ( system mistake code ) Indication display:reverse,electric larceny,Open terminal cover and record,weak battery.LED: Calibration meter pulse indication and LED always light afterpower on, when there are pulse coming, the light will be off within 80ms.Output:Calibration meter pulse outputSystem diagnose:Monitor crystal oscillator when power on,EEPROM, FRAM MISTAKEParameter1) Rated voltage:240V2) Current:5 ( 80)A3) Frequency:50Hz4) Constant:1600imp/Kwh
5) Accuracy Class:1.0 ( internal control -40% )
