DSSD/DTSD three phase multi-Function energy meter

Detailed Product Description

Use:
Model DTSD/DSSD three phase electronic Multi function kilowatt hour meter can precise measure following data:
Positive active time sharing (tariff) electricity energy consume;
Positive reactive time sharing (tariff) electricity energy consume;
Reverse active time sharing (tariff) electricity energy consume;
Reverse reactive time sharing (tariff) electricity energy consume;


Can set 4 tariff, 12 daily period of time, 12 year time zone, and can separately set Wenkend, 12 public holidays and spring. With RS485 communication port, infrared communication port, and active pulse output function. The specification confirm to : GB/T15284-2002; DL/T614-1997 ; DL/T645-1997



Function and Feature:
* Preset 4 tariff, 12 time zone, 12 sets of time period list, 12 time period, holiday also can be set according the client require.

* it can store 12 months history energy.

* Power and current direction can be distinguish automaticly, positive & reverse electricity can be measured separately
* Pulse width & frequence of total energy consume can be set
* Phase break supervise function: record the time of phase break, times and electricity used when phase break.

* LCD display, with back-light, when power cut, still can be displayed

* with infrared and RS 485 comunication port, and can be connected with GSM/GPRS wireless copy meter module

* Program operation with hardware switch and software password protection

* 1Hz clock pulse output

* with inner and outer double WDT circuit, with good electromagnetism compatibility

* with sound/light control alarm function, alarm item can be set by PC software

* with detect function of cover openning, can record the times of cover openning, and time of latest 10 times openning

* Lowest power loss, when battery is lack of voltage or lose voltage, can be alarmed automatickly

* Measure active and reactive energy in different time, import or export measure can be set.


Basic parameter:

* Daily clock error: 0.5s/day, 1.0s/day after power cut

* Total pulse output width: 80ms, 20ms

* Battery supply keep current after power cut: ≤30μA (battery voltage 3.6V)

* Voltage influence: with good stabilization in 20% changing

* Rated voltage: 3X220/380V (3phase 4wire); 3X 380V (3phase 3wire)

* Rated frequence: 50Hz

* Accuracy: class 2

* Basic current: 3X1.5(6)A, 3X5(20)A, 3X10(40)A, 3X15(60)A, 3X20(80)A

* Power loss: 1W/2VA (voltage circuit); 1VA (current circuit)

* Prevent no load logic circuit.

* Data can be memoried 10 years

* Standard working temperature: -30℃~55℃

* Limit temperature: -40℃~65℃
