DDSY450
Single-phase Electronic Prepaid Meter
Ò»: General description
The DDSY450 Single-phase Electronic prepaid Meter is a measuring instrument, for which the user should pay for the electricity to the power-supply department and then use electricity within the limit of certain amount and load. It adopt the imported ADE7755 from America to measure the pulse, and also use the latest encryption IC card to transform the data between the user and the manage system. So, it can ensure the safety and reliability of the data. One card for one user makes it have forward and backward measuring function. It can be used for the citizens' areas to control the articles and for the city and countryside to improve the electric network.
Every performance of this product complies with all the technical requirement for the electronic single-phase advance-paying meter in the IBC1036 and GB/T17215-98 standard.
¶þ: Main functions and Characteristics:
Precision of the energy measure is stable and can hardly be influenced by frequency, temperature, voltage or ultra harmonics. It need no adjustment and therefore can extend the probation period.
Use the encryption card to transform the data, so the date is safe and reliable.
The power-off date can be reserved automatically for over 10 years.
Purchase the electricity in advance, purchase before use it, switch off if used up, without any electricity on credit.
.Have the warning function for the residual electricity, the warning number can be initialized, and the nixie tube can flash to warn.
With any lose or destroy, the card can be supplied again at any time, without any economic lose of the both parties.
The nixie tube of ËÄλ can display the residual electricity of the meter and the code of the operating state of the meter.
Have the function of limiting load. if the load is bigger than the threshold, the meter will switch off for protection and the nixie tube will display err3 to show the mistake. Then the ICcard can recover the electricity in about 3minutes.
The IC card can not be mixed, one card for one meter, and one purchase for one effective read.
The card should be insert properly, after each right operation the nixie tube will display the residual number. In order to read the number properly, the user should not draw out the card unless the residual number has been displayed. Or it will cause lose due to the lose of electricity.
If the card is destroyed it shows: IC-0
If the code of card is wrong it shows: IC-1
If the code of the system is wrong it shows: Err1
If the user' s number is wrong it shows: Err2
Èý. Specification and Main data:
Specification
Basic inaccuracy
Starting: in case that the rated voltage, rated frequency and power factor are all1 and the loading circuit is 0.4%Ib, the meter can work normally.
DZ¶¯: the meter has the circuit avoiding DZ¶¯
Operating voltage: 160---275V
Power consumption:
