DDSD285 (T) fully electronic active energy electricity meter, conforms
To IEC61036 and IEC61038 standards. Features innovative structural
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.

Main functions:
1) Measured total energy and energy of every tariff.
2) Reverse energy is measured and added to the corresponding forward energy
3) Energy measuring range is from 0 to 99999.999kW. H
4) Offers 4 sets of schedules to realize multi-TOU controls
5) Day can be divided into 10 periods with 4 tariffs for each schedule
6) Work-off days can be also programmed in a week
7) Stores energy billing day of each month
8) Billing day can be set within 1-28 of the month
9) Can store history energy data for 12 months
10) All data may be accessed via personal computer (PC) or hand hold unit (HHU)
11) Records last five times of case opening during normal operation and once in case of power failure
12) Other events will be recorded including power down, program setting and current reversing
13) Total times of each event plus their respective latest five starting times and ending times can all be accessed via PC or HHU
