single-phase electronic prepaid watt-hour meter is a new generation of metering instrument that integrates functions of electric energy metering with load control, anti-electricity stolen, prepaid and user information management, etc. It adopts special prepaid control chip on the basis of high-performance electronic anti-electricity stolen watt-hour meter, it is made completely accordance with national standards GB/T17215-2008 and international standards IEC62053-21. It is the ideal product for current reformation of power utilization system, realizing commercialization of electric energy, solving the difficulty of collecting fees, as well as regulation the load condition of power grid. |

FUNCTIONS AND FEATURES |
♦ Active single-phase electric energy metering, it needs not to regulate for long-term operation.Measures forward/reverse active energy; Reverse energy accumulated as forward ♦ High-strength encryption algorithm, one card for one meter, the cards can't be used each other, with favorable safety and reliability. ♦ Prepayment functions: Purchase electricity before use, meter pre-alarm when remaining energy decrease to preset value and cut-off power when use it out. (Optional function: Non-cut off electricity during holidays and nights even charge is overdraft. Overdraft energy can be set.) ♦ When inserting the user card, the watt-hour meter writes electricity utilization information back on the card, it is able to know the running condition of watt-hour meter through the computer based electricity-vending system. ♦ Limit of purchasing electricity to prevent from illegal hoard ♦ After power failure, the data in the meter can be saved for more than 10 years. ♦ Adoption of high-capacity magnetic latching relay, wide working voltage range, high reliability ♦ Insert the electricity -purchasing card, the watt-hour meter would display the residual electric quantity and accumulated electricity consumption. ♦ 8-digital high-brightness Scrolling LCD display, or 5+1-digital register and 4-digit LED tube double display. ♦ Unique anti-electrostatic design of interface of IC card, which is able to withstand the attack of 8kW static electricity. ♦ Optional functions: RS485 and remote infrared |
