DDS228 single-phase electronic active energy meter

DDS228 single-phase electronic active energy meter DDS228 single-phase electronic active energy meter system I am using microelectronic technology and special large scale integrated circuits, application of digital sampling technology and SMT technology and other advanced technology research and development have complete independent intellectual property rights single-phase two-wire active energy meter. The table technical performance in full compliance with IEC? 62053-21 international standards relevant technical requirements a single-phase active energy meter can accurately and directly measure the rated frequency 50Hz or 60Hz single-phase AC active electric power grid load consumption. The table consists of seven LCD display has a function of power, and built far infrared and RS485 communication modules to facilitate connection with a variety of AMR system, with good reliability, small size, light weight, beautiful appearance, easy installation. Second, the function? Can? Special? Point ?? 35mm? DIN standard rail installation, complying with DIN? EN? 50022 standard, or front board installed (mounting holes center distance 63? Mm), two installation arbitrarily selected by the user. 6 pole width (Modulus 12.5mm), in line with JB / T7121-1993 standards. Optional 6 + 1 (999999.1kWh, default) or 5 + 2 show, by the user through the far infrared or RS485 data communication port set arbitrarily. Standard configuration pulse output passive (polarity), optional remote pulse output passive (polarity), in line with IEC? 62053-31 standard. Equipped with a far infrared data communication port and a RS485 data communication port as standard communication protocol in line with DL / T645-1997 standard, optional additional protocol. Three LED indicate power status and power pulse signal and data communication status. Standard configuration does not detect load current direction of the trend, you can choose to automatically detect the load current flow direction, by a single LED indicator. Single direction measure single phase two wire active energy consumption, regardless of the load current direction of the trend, in line with IEC? 62053-21 standard. Standard configuration type S wiring (bottom inlet, outlet from top) for direct connect to use, you can choose the access formula using CT (Product Configuration code FC) and PT? &? CT connect operation (Product Configuration code EC) . Standard configuration short terminals cover, optional extended terminals cover, protect to use safety. "Jiangxi Huajian Power Industry" factory direct. Microcomputer integrated protection device, motor insurance chronograph, rail meter, digital ammeter, digital voltmeter, frequency meter, power meter, power factor meters, multi-rate meter, multi-function table power digital instrumentation.
