DDSY3666
YONY
Ⅰ. Applications, Features and Sphere of Application
Main features: Application of computer management, power utilization after purchasing power; limitation of maximal service power within the rated current range (prescribed by power supply department); one card only for one watt-hour meter, no electricity interruption even with the loss of the card and ensuring the power continuation after the re-registration; bilateral transmission of data and automatic power- cutting off to warn users to purchase power ; automatic switch-off operation when the electric quantity hits zero ; certain software design of anti-electricity-theft and so on .
Installed in the watt-hour meter boxes indoors or outdoors, the DDSY3666 serial of electronic watt-hour meters apply to active power meter of frequency of 50HZ or 60HZ. Its ambient temperature ranges from -10℃ to 50℃ and its relative humidity is no more than 85%. It should stay away from the influence of corrosive gas, dust, salt mist and condensation.
Ⅱ. Specification and Main Technical Parameters
1.Specification
2. Intrinsic error
Note: Ib to be basic current, Imax to be rated maximum current
3.Starting current:
Under the conditions of the rated voltage, rated frequency and power, meter class I starts at 0.004Ib, meter class II starts at 0.005 Ib.
4.Watt-hour meter running without load:
When the line circuit of the watt-hour meter does not have current, and the line circuit has 115% rated power, the output pulse will not be more than one.
5.Power dissipation≦2W、10VA
