Single-phase electronic pre-paid watt-hour meter(digital card type single-phase electric energy meter) measure the special-purpose chip as the core with total word, intelligent electric energy, combine single slice quick-witted can the high performance of treatment technology measure instrument. Totally digitized electric energy measures, charges multi-functional products of new generation such as controlling, burglar-proof electric management, user's information management, etc, intelligently. This electric energy meter is a power consuming system of a present reform, realize the electric energy is commercialized, it is difficult and regulating the ideal products of the load state of the electric wire netting to solve and charge.
This product may install in indoor or the outdoor electric instrument box. Adapt in the ambient temperature for -20~+55º C, the relative humidity is not bigger than under 85% conditions to use. This product each performance conforms to GB/T 18460.3-2001 Prepay to consume electricity completely Can Table in the standard stipulation.

Main Function and Characteristic
1. The hardware of the standard IC card encrypts and chargtes in advance, supply power in the department in order to sell and purchases the electric card(IC card)Way last electric consumption it collect in advance it spend after buying electric rate, user.
2. Collect complete digitization and measure, electric consumption reveals, the prepaid fee is controlled, read the card, many kinds of functions such as the burglar-proof electricity of intelligence are combined together, have extremely high dependability.
3. Pas load to protect. Load exceed set for most large electric current 20-30% some time continuously, cut off, supply power return circuit, The electric energy meter will shut the floodgate automatically in some time if the electric energy meter delays time automatically.
4. It is encrypted again, totally ensure the safety of data, correct, reliable that there are much IC cards of power consumping through software and hardware. Through designing specially, Power consuming record user surplus electric consumption of the ammeter insert Carlos. And add up to electric consumption and steal the behavioral information of electricity at the IC card.
5. The complete bayonet base protects the circuit, can prevent various behaviors attacked to the bayonet base maliciously effectively.
6. Reveal surplus electric consumption, reveal-figure number is five(four integers, a decimal)
7. Surplus electric consumption reaches and predicts alert electric consumption, the number is in charge of glimmering and revealing surplus electric consumption, need to input new purchasing electric consumption in order to point out users.
8. It is sure to be worth cutting out automatically that the electric consumption owed reaches, input new purchasing electric consumption(deduct the electric consumption overdrawed)And then resume supplying power automatically.
9. While losing electrical power, keep the data automatically, resume the data automatically after the incoming telegram.
10. Computer +special-purpose IC card person who read and write charge management software commit the administrative system of sale of electricity.
11. Compare and analyse the information of recording, the administrative system can be listed and suspected that steal the behavioral users of electricity, for the focal point check, reduce and defend, check that steals the behavioral work load of electricity.
