single phase electronic prepayment energy meter adopts micro-chip measuring energy

DDSY5881 single phase electronic prepayment energy meter adopts micro-chip measuring energy, conforms with standard IEC62053-21. This meter use full sealing construction, advanced single chip process system to collect process and store data. It with reliable capacity of anti-electromagnetic, low consumption, high precision, theft-proof, high load and long life.

Main feature: Purchase electricity first then used electricity by PC management; it can limit max consumption power based on rated current range(limit by power supply department); one meter with one card, one card special for one meter, lose card will not lose electricity, it’ll can be used again by replacement card. Card with meter will transmit data each other, will auto cut electricity and alarm user to purchase electricity; when electricity is zero, it’ll auto power off. And it has anti-theft software design etc.

DDSY5881 electronic meter used for frequency 50HZ or 60hz active energy measurement. Installing indoor or meter box of outdoor. The environment temperature is -25~65°C, relative humidity less than 85%. And there are no corrosive gases etc.

Start:

     Under the condition of refer voltage, frequency and power factor is 1 and class one meter is 0.004Ib, class 2 meter is 0.005Ib.

Running with no load: When voltage is 115% of refer voltage and no current, impulse outputs is less than 1pc.Power consumption:<2W,10VA

III Main construction and work principle

Meter main construction

Meter out case use ABS material, hard and good sealing.

Work principle

The meter sampling the current and voltage through splitter and voltage divider, conversion by A/D,DSP multiplier, D/F transform, frequency division etc output impulse signal to CPU, after operation the data will display on the LCD and drive pulse indicator blink.
