China Ddsd2800 Single-Phase Multi-Function Electricity Meter Watt Hour Meter

DDSD2800Single-phase Multi-function Electricity MeterGeneral Description
DDSD2800 Is a type of fully electronic active energy electricity meter. The meter features Its Innovative structure design and reliable electric capabilities,so It Is an ideal option for measuring household electric energy with time-of-use (TOU) as well as balancing electricity load better.

Characteristics
l Active/reactive energy measuring
It can measure total energy and energy of every tariff. The reverse energy Is measured and added to the corresponding forward energy.
l RTC
An external real time clock realizes the timing and TOU
l TOU control
It can offer 4 set schedules to realize multi-TOU control. The day can be maximally divided into 10 periods with 4 tariffs for each schedule.
l Energy record
It may store history energy data for 12 months. AII data may be accessed via personal computer (PC) or handhold unit (HHU).
l Display
It can display by LCO indicator during both power supply and power failure. It supports automatically scroll display mode and button pushing display mode.
l Event log
It can record case opening during normal operation and once of such event In case of power failure. The other events will be recorded including power down,program setting and current reversing. The total happening times of each event and ending times can all be accessed via PC or hand hold unit (HHU).
l Communication
It can communicate via an optical port and RS485, which realizes the meter reading and parameter setting.
