Application

DDSF5168, Single phase two wire active electronic multi-tariff watt-hour meter, LCD display.

The meter is used to measure 50Hz or 60Hz active energy consumption from single phase two wire AC electricity net.

The meter adopts LSI (Large-scale Integration) and SMT manufacturing technique, the key components and part all adopts long life type.

The meter is widely used in office buildings, shopping malls, residences, airports and metro, etc.

The meter has function of different tariff measure for different time period.

  Functions and Features  

♦Active energy measuring: It can measure total active energy consumption. The reverse energy is measured as forward active energy.

♦TOU control: 4 tariffs (pointed period, peak period, smooth period and trough period),8 time intervals. ( can set according to the client's requirement.)

♦RTC: Real time clock, leap year shifting automatically. Broadcast time calibration.

♦Energy Record: It can store energy in billing day of each month. The billing day can be set within 1 to 28 of one month. The consumption data can be reserved for 12 months. All data may be accessed via personal computer (PC) or hand hold unit(HHU).

♦Display: It can display by LCD indicator during both power supply and power failure. It supports automatically cyclic display mode and button pushing display mode. Display items can be set by user via PC or HHU.  

♦Battery: It is equipped with build-in lithium battery, which could be used for a long time and is environmental-friendly.

♦Event Log: It can measure MID, record the happening time of programme and power down and their times. Record meter resetting, time interval setting, and clock setting etc.

♦Communication: It adopts isolated RS485 communication, which is designed for preventing from the lighting strike. It can also communicate via infrared interface, which realizes the meter reading and programming.

♦Indicators: Reverse directional ,pulse test , communication

♦Meter reading unction when power off.

♦May setup the meter number, bureau number, time period, rate, date, password and initial electric power.

♦Password and program switch protection is also available to be applied to the date copying components.
