Detailed Product Description 1. measurement Function The meter will record and display total active energy, the reverse energy will be accumulated to total energy in absolute value. The meter will automatically calculate the total consumed energy and remaining energy when measuring each ***** will record, display and store active MD, the date and time the demand occurred since the latest energy purchase. ***** and load Protection function The meter has the functions of automatic disconnection under outage and delay connection under power on to insure the relay will not be damaged if short circuit occurs when the meter is installing The meter has the function of protection against under-voltage. When the meter identify the current voltage is under limiting operation voltage, the meter will automatically disconnect the relay. When the voltage restores the normal voltage, the meter can automatically connect and restore to supply the power Automatically deducting the owed fee: When consumer inserts IC card to upload the energy after purchasing the energy, the meter will automatically deduct the owed energy first if the owed energy exists 3.Prepayment Function One IC card for one meter: IC card adopts ISO standard, special data encryption algorithm, verifying and error-correcting algorithm to ensure the data are correct and reliable Power disconnection control: The meter will disconnect the consumers load when the remaining energy is 0. Remaining energy warning: the meter will warn in audio and visual for 5 times/1kWh when the remaining energy inside meter is less than or equal to enegy alarm limit Hoarding energy function: The meter will not allow to upload the purchased energy from IC card until the sum of purchased energy in IC card and the remaining energy inside the meter is less than the max hoarding energy threshold 4.Data Communication Function IC Card data communication: The purchased energy and meter parameters can be preset and the meter data can be read through using the Registration Card, Purchase Power Card and Function Card. Infrared communication: It can preset the local meter parameters and read the meter data through the infrared communication port and HHU, one HHU can read the meters at least ***0 units. ***** function When the meter is replaced, the meter data inside the old meter can be copied into the card. When the new meter is finished the installation, the copy card can be inserted into the new meter and the meter data of the old meter will be completely copied to the new meter, its not necessary for consumer to change the cards or re-register his account to continue consuming the energy.
