DDS70-M single phase multi-functional meter

With the deregulation of the energy market, in combination with a changing cost situation, new flexible tariff structures and a modern energy management are required. Remote metering and the standardization process become more and more important. The DDS70-M single phase multi-functional metercreated a new solution which will benefit both Utilities and the end user. The meter comply with the relevant IEC standards and manufactured under ISO9001 standard. Measuring and registration Meter records import and export energy flow in separate registers, and add the values in both directions as the labeled energy consumption Legible LCD Display The meter is equipped with a large LCD of viewable size . -Automatic scroll mode - Manual scroll programmable data set and sequence - Utility mode for testing - Display available without main power (Option) - LCD back-light (Option) Real Time Clock The time clock used by the meter synchronized by a quartz crystal clocking unit with an accuracy of+/- 5ppm at 25°C. Flexible Tariff Management Benefit from an internal RTC, full Time of Use (TOU) function is realized. A tariff program are managed by the RTC which suitable for the most complex metering applications. The meter is able to generate End of Period information as defined by the user, usually based around billing dates. The non-volatile memory is able to save energy information for up to 12 billing periods. This removes the need to visit the meter on a frequent basis. DDS70-M has 4 kinds of tariffs and 12 intervals in 24 hours for each day, which can be programmed flexibly. Interval 1 to 12 of each day can be combined with tariff 1 to 4 according to various requirements, these combination is called Tariff Set. In addition, the meter has 30 holidays can be individually set with different kinds of combination of tariffs and intervals. Maximum Demand information can also be measured for all tariff rates allowing optimum billing of high consumption customers in particular. Maximum Demand The meter calculates and displays Maximum Demand data for each tariff register. The Maximum Demand window is configurable thru software as 1,5,15 minutes interval. Maximum Demand is displayed in kW and can be reset to zero automatically or manually. Load Profile The meter has three load profile channels which can store optional data for up to 365 days. And the interval length can be set from 1 to 60 minutes.
