I. Overview DDS228 DIN rail mounted single-phase electronic active energy meter I am using the advanced microelectronic technology and dedicated LSI application of digital sampling technology and SMT process technology developed with completely independent intellectual property rights single phase two wire active energy meter. The technical performance of the table in full compliance with international standard IEC 62053-21 relevant technical requirements of a single-phase active energy meter can accurately measure the rated frequency 50Hz or 60Hz single-phase AC power grid load active energy consumption. Table 7 LCD display function of power, and built-in far-infrared and RS485 communication module, convenient, with good reliability, small size, light weight, beautiful appearance, easy installation with a variety of AMR system. Features ● 35mm DIN standard rail mounting, in line with DIN EN 50022 standard, or in front of the board installed (mounting holes center distance 63 mm), installed in two ways users can choose any. ● 6-pole width (Modulus 12.5mm), in line with standard JB/T7121-1993. ● Optional (6 +1 999999.1kWh, default) or 5 +2, far-infrared or RS485 data communication port arbitrarily set by the user through. ● standard pulse output passive (polarity), select passive remote power pulse output (polarity), in line with the IEC 62053-31 standard. ● equipped with a far-infrared data communication port and an RS485 communication port, the standard configuration the communication protocol compliance DL/T645-1997 standard, you can choose other communication protocols. ● Three LEDs indicate power status and power pulse signal and data communication status. Standard configuration does not detect the direction of the flow of load current, automatically detect the flow of load current direction can be selected by a separate LED indication. ● Single direction measurement single phase two wire active energy consumption, regardless of the direction of the flow of load current, in line with standard IEC 62053-21. ● Standard configuration type S wiring (Inlet from bottom, outlet from top) for direct connect use to select the access to use CT (Product Configuration code FC) and PT & CT connect operation (Product Configuration code EC). ● Standard configuration short terminals cover, may select extension terminals cover, to protect the safe use of electricity (Product Configuration code GF).
