It is the single-phase active energy watt-hour meter with multi functions of anti-electricity theft on an induction watt-hour meter, its performance is the same with that of DD862 series watt-hour meter, even, the connection circuit is completely same with that of DD862 series watt-hour meter, so it is convenient to main-tain and operate it. Besides, its technical parameter is the same with that of DD862 series watt-hour meter too.
Normal working conditions and installation conditions
1. Specified working temperature：-10℃~45℃；
2. Utmost working temperature：-25℃~55℃；
3. Relative humidity: ≤85% (at environment temperature23℃)；
4. There shall be no corrosive gas and dust, mold and insect in theair.
Main Technical data
1. Anti-wire inversing
If the electricity is stolen by the way of exchanging the inlet wire and outlet wire of watt-hour meter, this watt-hour meter register which can accumulate positively and negatively still counts positively as per speed of 1~5 times, however this watt-hour meter rotates inversely, so that the thief can't steal the electricity and is punished.
The metallic hook is connected in the meter that can't be removed, so that the electricity can't be stolen for stopping running of watt-hour meter, which is resulted in metallic hook is unconnected.
