Main Usages:
Designed for timesharing electricity metering of new or reconstructed single-phase users. With prepayment function, it is particularly suitable to solve payment payment-collecting difficulties in residential areas, organizations, factories, mines and schools, ect. 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, Provides precise positive-negative active energy metering and one-way accumulation. Used for power metering and advance purchase of AC single-phase current rated.
2. Advance 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.
3. Storage of leave-factory serial number, meter constants, initial data and the users name and address etc.
4. Alarm and switch off when overload. Alarm at low remaining power to remind user of timely purchasing.
Main Characteristics:
1. High accuracy and import special metering chip. High accuracy, sernsttvity 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. Hence the workload of watt-hour Meter testing and checking-out of electric departments is considerably reduced. Obviously better reliability than it's similar.
3. Stable operation. Better stability for its wide range working voltage.
4. LED display, bright and clear prevent counter data form losing at any times
5. Sing-phase, 3-phase and multi-functional prepayment watt-hour Meter can share a single electricity supply system. 6. With meter reading card and a portable computer. Once about 1500 metes can be read.
Special promise: Life time maintain, respond to customers within 24 hours in Chenzhou city.
