Sell electric watthour meter

详情

Summary : Single-phase static watt-hour double rate meters are made of static single-phase power meter modules and rates modules, LCD display, high reliability, both infrared communication functions. The table has high accuracy, good stability, and strong Shock notable features. Supplying advanced and reliable measurement tools for the single-phase time-of-use measurement. The phenotype consistent with the national standard GB/T*********4 "multi-rate (TDM) Meter" and GB / T *********8, "one and two grade static AC energy ammeter", with the Statute DL/T*******7 "multi-functional table communications statute." And the products meet the technical conditions of time table meter of Zhejiang residents. The main functions and features : Under electricity peaks and troughs were measured. Electricity can be stored with current and last month. data The largest rate of eight hours for peak hours and valley hours respectively electricity metering for different rates. Using LCD also shows that total, the Valley of electricity blackouts ,which facilitate meter readiing, handheld computer can be used while it showed Table parameters. Using handheld computer of Zhenzhong company, reproduces energy all the data table by infrared (table, the total power consumption, peak electricity consumption Valley, At present, rates, etc.). High reliability, minimal consumption of standby power batteries, long life. Entry forms (spaces can be reduced and operate table without input the Table) infrared installed or meter reading meter clock, hours and electricity bottom. Pulse output. . RS**5 interface can be expanded. With the clock hardware and software compensation function.
