Detailed Product Description

The Energy Meter Main Technical Parameter 

Main Usages:

Designed for time sharing electricity metering of new or reconstructed single-phase users. with prepayment function. it is particularly suitable to solve payment collecting difficulties in residential area, organization, factories, mines and schools etc. it is preferable 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 negative energy metering and one-way accumulating.  Used for power metering and advance purchase of AC single phase current rated.

2. Single-phase timesharing electricity metering, 4rates and 12time-periods.

3. Automatic monthly settlement. Set a meter reading date and 12months`consumpution data can be reserved.

4. Load curve recording: Set a representative day and power consumptions at each right hour from 0-24h can be recorded.

5. Advanced purchase quantity, preset maximum load limit and IC card password. IC card transfers data and realizes data (including total consumption, remaining quantity, accumulated quantity and total purchases etc.) backward reading.

6.  Storage of leave-factory serial number, meter constants, initial data and the users name and address etc.,

7. Alarm and switch off when overload. Alarm at low remaining power to remind user of timely purchasing.

8. Far infrared communication function. Comply with stipulations of DL/T645-1998 Multi-functional Watthour Meter Protocol.

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 its similar.

3. Stable operation. Better stability for its wide range working voltage

4. LCD display and comprehensive data.

5. Single-phase, three phase and multifunctional prepayment watthour meter can share a single electricity supply system.

6. With meter reading card and a portable computer, once about 1500 meters can be read.
