Single phase STS type prepaid meter - DDSY-T10

1.When the meter recognizes a power outage,all billing data are transferred to non-volatile memory at this time

2.Upon restoration of AC power,all self-diagnostics are completed and all data is retrived from non-volatile memory

3.It could prevent the coemption of kwh. When the purchased kwh or the purchased kwh pluse the remain kwh is more than 999999.99kwh,the kwh injection will fail. The max coemption value could be modified through communicaiton,and the default value is 999999.99Kwh.

4. Using standard infrared meter reading device

5. Aim at the infrared port to read the data, and at the same time, it also could change the data in the meter

6. Switch off when remain energy is zero

When the remain energy is less than the alarm energy, LED would flash(The alarm energy could be modified through communication. The default value is 1.000Kwh)

7.When the remain energy is 0,the relay will open which would be displayed on LCD

8.Condition of switching on: the remain energy is more than 0 after charging, the relay will switch on

9.Switch off when the over loaded

10.When the instantaneous power value is more than the threshold, the relay will open(The threshold could be set through communication, and the default value is 2500W)

11.Condition of switching on: When the power become normal, after 20 seconds the relay would switch on

12.When on power, the user could read total energy, remain energy,bought kwh recently, meter address, impulse number,communication password, alarm kwh, times of switching off

13.When off power, the meter will record the total kwh, remain kwh and impulse number

14.Charge the kwh through the key pad, the meter will record the kwh

15. High security, reliability and convenience to buy the electricity
