DDS3666 active Single Phase Two Wire kWh Meter LCD Display Multi-Rate, Electronic Power Meter with rs485

1. Starting: when reference voltage, reference frequency and power factor is under 1.0           condition, meter class 1 is 0.4%Ib, and meter class 2 is 0.5%Ib , the meter can start and         normally measure.

2. Shunt running: the meter has anti-shunt running logic circuit. when voltage circuit plus     1.15 times reference voltage, and there is no current in current circuit, the test output of      meter will be no more than one pulse.

3. Power consumption：≤1W（5VA）。

4. Environment condition standard working temperature：-25℃～55℃ 

  limit of working temperature：-25℃～60℃ 

  note: Special requirement of working temperature limit：-40℃～70℃

Basic Error

1.Energy measuring function
    To measure total active energy, reversal energy accumulated as positive, data always       displayed in the top line on LCD

2. Output Interface
    Active passive pulse output interface with optocoupler isolation. Pulse light blinks when   there is pulse.

3.Reverse function
   Reverse Tamper Light alarms, when the energy reverses. 

4.Display function
    The meter uses LCD in a clearer display and nicer appearance. When there is an external  power source, the total consumed energy is displayed in the top line, while the other items   of power rate, current, voltage and demand are displayed in the lower line in turns with an      interval of10 second . If there is no external power source, the meter will be backed up by     battery, and the meter will only display the total consumed energy.
    When energy-theft by neutral missing happens, the meter will display total consumed        energy in the upper line on the screen, and power rate, current, rated voltage and MD will      be displayed in the lower line in turns one by one with an interval of 10 seconds.

5. Backlight function
    When it is working normally with external power source, the backlight is always on.
    When energy-theft by neutral missing happens, to save the power consumption, the           backlight will only work on the condition that the current reaches at least 5A.

6. parameter measuring function
    The meter measures voltage, current , power rate, demand. The interval of measuring        demand is 15 minutes among which there is 1 minute’s overlap between intervals.
