Single-phase multi-rate watt-hour meters

الوصف

Main Usages: Characterized with long service life and free-maintenance operation, it is especially suitable for single-phase timesharing electricity metering in residential areas in the city or countryside. It is a preferable product in promoting the management level at demand side, inducting the users to better power consumption style to improve power efficiency and electric sources collocation. Main Functions: 1. Both-way electric energy metering. Provide precise positive and negative energy metering and one-way accumulating. 2. Single-phase timesharing electricity metering, 4rates and *2time-periods. 3. Automatic monthly settlement. Set a meter reading date and *2months`consumpution data can be reserved. 4. Load curve recording: Set a representative day and power consumptions at each right hour from ***4h can be recorded. 5. Standard serial data and far infrared communication and meter reading functions. Comply with stipulations of DL-t**5 Multi-functional Watt-hour Meter Protocol. 6. Pilferage proof (countercurrent pilferage and diffluent pilferage etc.) Main Characteristics: 1.High accuracy and import special metering chip. All-electronic design, sensitivity and reliability, wide overload endurance, low power consumption, small volume and light in weight; easy installation, convenient auto-control and function expanding. 2.Long service life. With SMT technology and world famous, long-life components employed, its accuracy is not affected by frequency, temperature, voltage and higher order harmonics. Random installation location. No adjustment is needed if it leaves the factory as complete machine. Checkout period can be extended. The workload of Watt hour Meter testing and checking-out of electric departments is considerably reduced. Obviously better reliability than it's similar. 3. The optimal use of its low-power design, in the large-scale use, could reduce the power grid line losses, improve the efficiency of the power supply; Stable operation, better stability for its wide range working voltage. 4. To facilitate networking: modular design, with standard RS **5 serial data interface, in line with the "DL/T*******8 meter multi-purpose communication protocol. " Users can easily extend local CATV net, GSM net, broadband net, public telephone net and radio or electric carrier wave network.
