DDZY150 single phase local fee control smart meter is a intelligent electricity metering product, which suit for measuring 220V/50Hz single phase active AC power. It has independent optical and RS485 interface, and also with standard interface of carrier communication module, which can work with carrier communication module from different suppliers. It can support for fee control function. With advantages of high reliable, high accuracy, long life, wide range and etc, it can widely used in city, country and enterprises where need to measure single phase AC power.
Standard: IEC 62053-21 Electricity metering equipment (a.c.) –Particular requirements –
2. Working Principle:
Measured AC voltage and current have been sampled and transported to professional metering chip, after digital processing, they have been changed to the pulse signal, which in direct proportion to active power, and then sent to microprocessor. Microprocessor would accumulate the pulse signal according to the tariff, then get total power and tariff power and put them in register. At the same time, the microprocessor finishes the function of display and changeover with external messages. Please take attention to the Figure 1
