Single Phase Electronic Watt-Hour Meter DDS155(LCD)

Single phase / three-phase electronic used the entire digitized electronic meter special-purpose chip group.. It's a new generation of products, it has the complete digitized electrical energy measurement, the intellectualized charge control and the user information management the multi-purpose functions and so on. And it is an ideal product on the current situation of reforming electric power consuming system, commercializing electric power, solving the problem of the collection of charges, as well as adjusting load state of electrical network.
 

Main functions and features:

1.     Complete digitized electrical energy measurement, prepaid control, LED electricity amounts display, has high reliability

2.Alarm/ overdraft way, alarm/ overdraft electricity amount, the maximal hoard amounts for speculation can be set.

3. Perfect interface protecting circuit keep the meter from all kinds of vicious attack. ( The antistatic ability may reach more than 80 KV).

4. Using the high quality keeping magnetism relay can heighten the reliability.

5. Perfect power source and electromagnetism compatible design, are suitable to the strong electromagnetism disturbance and big occasion of power source fluctuation.

6. Over-voltage protection, over-current protection, overload protection, real time power is demonstrated.

7. LED or LCD display alternately shows the remaining capacity, the cumulative electricity consumption, the current power.

8. Improve the power and electromagnetic compatibility design, suitable for strong electromagnetic interference and power fluctuations occasions.

9. Sealed dustproof, waterproof design, the case material with excellent flame-retardant and corrosion-resistant, anti-aging properties.

10. Strengthen the protection of IC card port, able to withstand the vicious attacks, no damage to the power meter, do not lose data, do not delay action.

11.Can be equipped with infrared, RS485 interface, or carrier communication module.

12. Three-phase power supply, three-phase four-wire can work as long as there is one phase.

13. Suitable for digital card smart meter charge management system(SKZHSFN3.17-SD), hydropower card charging management system(SKZHSF3.17-YKT).
