Application
DTSD450 and DSSD450 series three-phase electronic multi-function watt-hour meter is a new generation product that can measure reactive energy and active energy with multi-tariff, it is designed by modularization, its multi functions can be combined freely to meet users requirements. Each performance index of it conforms to standard D L/T 614-1997 Multifunctional Watt-hour Meter and standard DL/T 645-1997 Multi-function Watt-hour Meters Communication Protocol as wellas total technical requirements for three-phase electronic multi-function watt-hour meters stipulated in standard GB/T 17215.321-2008/IEC 61036.
Main Technical data
1. Class index: active energy:class 0.5s, 1, reactive energy: class 22. Clock error: 0.5s/day3. Reference temperature: 23°C4. Data protection: data stored time after power off: 10years5. Environment conditions:specified working temperature: -20 ~45°CUtmost working temperature -25 ~55°CRelative humidity: 85%( at environment temperature 23 )
Main functions
1. Measurement functionCan measure active energy and reactive energy respectively,and have separate active and reactive pulse signal output interfaces.2. Multi-tariff functiona. Four tariffs, ten time intervals.b. Calen dar for a century (1996-2095) can switch automatically.c. Record and store the total active energy and reactive energyand active energy and reactive energy under kinds of tariffs.3.Demand statisticsa. Record active max demand and its occurring timeb. Demand statistics adopts slip method.c. Max demand is stored as per month.d. Automatically alarm and trip for overload4.Record voltage lossa.Record 9 voltage loss and information of power failure,also, can record their initial and restoring time.b. Record total active energy and reactive energy of novoltage -loss phase5.Programming and meter readinga. RS485 communication interfaceb. The programming and meter reading are performed byRS485 communication interface, infrared communicationinterface and palm computer, also it can perform meterreading through remote controller and alternation displaying.6. Meter reading at zero o'clocka. The setting day for meter reading is 1st~28th of every month,the meter can calculate and store the data in the last monthat zero o'clock of setting day.b. Can store and display calculated data for past threemonths at the same time.7. Meter reading at power offThe meter is provided with individual meter reading batteries,so it can finish meter reading at power off.
