▷Product Overview
DDZY8888 single-phase remote control smart meter charge (carrier) is my company to develop and produce a new generation of intelligent high-tech energy metering products. It MCU + measurement chip technology, using today's latest integrated circuit technology, according to the meter on international (IEC) standards and China's power standard DL / T614-2007 "multi-function meter", DL / T645-2007 "multi-function power meter communication protocol ", GB / T 17215.321-2008" AC measuring equipment - Specific requirements - part 21 section static active energy meter (1 and Level 2) ", GB / T15284-2002" tariff applications special requirements "Q / GDW 364-2009 "single-phase smart meter technical specification", Q / GDW 354-2009 "smart meter functional Specification", Q / GDW 355-2009 "single-phase smart meter type specification", Q / GDW 365 2009 "smart meter information exchange security certification specifications" and other design and manufacturing. It combines measurement, cost control, monitoring, alarm, display, freeze, RS485 communications, infrared communications, wireless communications functions, implement a single residential users of electricity metering and power information acquisition and storage.
Remote control meter fee, local main achievement measurement functions, no local accounting function, just a meter measuring instruments and control actuators;Accounting mainly done by remote master / vending system,Meter receiving remote vending system issued wind up, allowing the closing, copy the data back to the command, the data exchange process required by strict password authentication and security certification, compliance with DL / T645-2007 and filings. When the user arrears sent by the remote master / vending system wind up command that allows users to power, when users recharge, remote master / vending system then sends a command to allow the closing, allow users to closing.

▷Features
● Having a positive, negative active energy metering function, and can meritorious electric energy based on this combination of settings.
● Have hourly metering function, active electric energy can be the appropriate time rates were accumulated storage.
● Can store the month, on January, on February ... on December consumption data, the monthly billing period can be set for any time of the day the whole point.
● Tariff calculation on the remote system to complete the sale of electricity is not stored in the table, show and electricity tariff related information. Meter send receive remote vending system under wind up, allowing the closing, data copy to read instructions.
● In ensuring the safety case, the electricity meter within the parameters set by virtual media.
● Secure authentication and encryption requirements: meter via virtual media to set the parameters, data copy to read, when issued remote control commands to operate, require password authentication through rigorous safety certification, in order to ensure safe and reliable data transmission.
● Measure voltage, current (including neutral current), active power, power factor. Measurement error (reference error) does not exceed ± 1%.
●A permanent record time data generating electrical energy meter is cleared and cleared when the event.
● The total number of recorded program, the last 10 times the programmed time, the operator code, data identification program item.
