DDSY1032 single phase static prepayment energy meter has been selected with advanced single phase power metering chips , and adopted with the SMT surface mounting and wave-soldering processes for manufacture; the product has the features of electric-larceny proof, high precision, high reliability, high overload, low power consumption, small volume, low weight, etc; it can be widely used in the time-share metering for the single-phase AC active power of urban and rural residents, plant enterprises, business, etc, to achieve the function of prepayment power purchase.

 

1. Accurately measure the electricity energy with power in the single-phase AC

2. Automatically prevent electricity theft, and the electricity with power in the reverse direction will be calculated into that in the positive direction

3. Board range, high precision, long life cycle, calibration and maintenance free

4. Prepaid electricity use with IC card, with built-in big-power magnet-maintained relay to control the power supply and shut down

5. One card for one household,adopting the special encrypted algorithm, with the good anti-counterfeit performance

6. Have the alarm function with light, and level-two warning for low electricity volume to buy electricity

7.When overload, automatic power shutdown and delayed recovery of power supply can be set up

8. Multi items of display contents, and the display content and time can be randomly set up

9. Triple data backups, and the data can be saved for ten years without loss after the power failure

10.Optional memory card,encrypted logic card, CPU card or radio frequency card

11.Optional display means including measurement instrument, LCD screen and LED digital tube.etc.

12.Optional communication interfaces including RS485 and infrared,etc. to fulfill the meter recording on the field or from the remote location

13. Optional function for multi charge rates

14. Matching can be vicious load recognition
