SINGLE PHASE ELECTRONIC PREPAYMENT METER
0verview
Single phase electronic prepavment meter (hereinafter referred to as the meter) usesmicroelectronic technology to measure electrical energy. Electricity meters that comply with thestandards of ab/t17215 .321-2021 and ab/t18460-2001 adopt a fully shielded and sealed structureand use advanced microcontroller processing systems for data collection, processing, ancstorage, They have good characteristics of electromaanetic interference resistance. low poweconsumption, power saving, high accuracy, anti theft, high overload, and long service lifeElectronic eneray meters are suitable for active energy metering with freauencies of 50hz or 60hzand are installed indoors or outside the meter box for use, Suitable for enyironments wittemperatures ranging from -30 to+70 ‘C, relative humidity not exceeding 85%, and there should beno corrosive gases in the surrounding air to avoid the effects of dust, salt mist, condensation, etc.
Functional characteristics
One card meter features: application of computer management, purchasing electricityfirst and then using electricity; Can limit the maximum usage power within the rated currenrange (limited by the power supply department): One meter, one card, dedicated for carcuse, no power loss if card is lost, and can be reused after card replacement; Electric cardscan transmit data in both directions; Automatic power outage alarm for users to purchaseelectricity; When the electricity level is zero, it automatically switches off the power supply.And it has certain anti theft software desian. etcThe electricity meter is equipped with aFeatures of multi card meter function:management system, which mainly records the amount purchased by the user in anencrypted manner on the electricity card, in order to achieve one meter with multiple cards(the user’s electricity card can only be used on the supporting electricity meter (the card’soffice number, area number, village number, and distribution number are consistent with theoffice number, area number, village number, and distribution number in the meter), and doesnot work on other electricity meters, Each table can use up to 40 different user numbers.

THREE-PHASE MULTIFUNCTIONMETER
Overview
Three-phase multifunction meter is a new generation of energy meter developed based on the overarequirements of the “unified and strong smart grid” construction of the state grid corporation of china, and on thebasis of the state grid corporation’s smart meter serie!standards.This electricity meter can accurately measurethe total active and reverse energy, various rate energy, and reactive four quadrant energy. it has the function orecording the maximum demand for active and reverse power, real-time measurement and processing oelectrical parameters such as active and reactive power, voltage, current, power factor, and frequency. lt hasfunctions such as time-sharing control, automatic meterreading, data storage of electricity and demand, loadcurve recording, and event data recording, it can fullymeet the needs of high-precision electrical energ)measurement and accounting for industrial and commercial users at checkpoints and large-scale specializetransformers. This series of electric energy meters adopts a large-scale digital signal processing chip (dsp), duinfrared communication,and large screen widfully isolated standard rs485 communication interface.technology and imported high-performance long-liftemperature lcd display.mount te.Adyancedelectronic components are used in manufacturing. The shell is made of high-strength, flame-retardant andesign, and high insulation strength and corrosioenvironmentally friendly materials, with a novresistance.lt is an ideal choice for state grid corporation’s centralized bidding for electricity meters and theconstruction of smart qrids for energy informatio
