Однофазный электронный многотарифный несущей волны

Application DDSIF3699 single-phase electronic multi-tariff carrier energy (hereinafter referred to as "Instrument") is mainly used for measuring time-sharing billing of civilian electricity so as to better balance network load. LCD display with the active energy measurement, infrared communication, power line carrier communication, remote control power-on and power-off, automatically freeze energy amount at daily 0:00 and freeze energy amount each hour within 24 hours. The instrument is the terminal device of a remote automatic meter reading system, which can accurately measure user's active energy. As well it adopts Low Power Line as communication medium, maintain reliable communication link with the concentrator in the substation and transmit data to concentrator. It is the ideal choice for residents to use electricity and remote meter reading. Comprehensive technical specifications of the instrument accord with the People's Republic of China national standard GB/T17215-2002 "1-and 2 static AC Power Meter" requirements, infrared communication line DL / T 645-1997 "multi-function meter communication protocol" requirements. Consistent with the PRC power industry standard DL / T 698-1999 "meter reading system technological conditions for LV users”Functions and features* the total active power and peak, normal and least energy measurement * Active power measurement in positive and negative direction, reverse-active power accumulated to the positive active power consumption. * Power line remote automatic meter reading. * By ways of software expansion of spectrum to realize power line carrier communication, accurate, reliable, high meter reading ability. * Mutual Auto relay function. * Capacity storage: Daily 0:00 consumption freeze. * Multi-rate function: can set four kinds of rates of sharp, peak, shoulder, off-peak and 14 time intervals by programming. The time intervals can cross 0:00. The minimum time interval is 15 minutes. The actual start and end time of any time interval and preset time error should be less than 5s. * Freeze settlement functions, save electricity amount of 0:00 and the latest three months. * Remote control power-on and power-off function. * IR programming, Power Line Carrier programming optional. * Infrared communication: through the infrared port realize function of instrument programming and meter reading. * Can freeze energy amount of each o’clock within 48 hours * Hardware clock RX-8025 control programs, time and date can be set, you can broadcast commands to correct the time. * No need response when broadcast time correction unless the time difference between master and secondary calendar and clock within the ± 5min. The broadcast time adjustment can only be implemented once every day. * LCD display, display with backlight and can indicate power-off on display.* Input and output interfaces:1. Passive impulse output interface with opt coupler isolation 2. Infrared remote control programming and meter-reading interface, refer to DL / T 645-1997 standard 3.
