DDS228 rail mounting power meter is a meter of the company many years of design experience, has launched a new generation of miniaturized smart meter. The energy meter with LCD display, the clock, the rate periods and other settings, and has a pulse output function; available RS485 communication interface for communication with the computer, which greatly facilitates the automated management of electricity. In ensuring the quality and stability of the premise, the series has a compact energy meter, easy installation, and has a very high accuracy and good resistance to electromagnetic interference, in full compliance with national standards and national standard GB/T17215 DL/T614-1997 -2002 in the relevant technical requirements 1 and 2 electronic energy meter. DDS228 rail-mounted single-phase electronic active energy meter system I am using has a dedicated LSI microelectronics technology, the application of digital sampling technology and SMT technology and other advanced technologies developed completely independent intellectual property rights of single-phase two-wire active meter. The meter completely accord with international standards IEC 62053-21 relevant technical requirements of a single-phase active energy meter can accurately measure directly rated frequency of 50Hz or 60Hz active energy in single-phase AC power load consumption. The table consists of seven LCD display has a function of power, and built far infrared and RS485 communication module for easy connection with a variety of AMR system, with good reliability, small size, light weight, beautiful appearance, convenient installation. Second, the features ● 35mm DIN rail mounting, in line with DIN EN 50022 standard, or board before mounting (mounting holes center distance 63 mm), two installation methods users can choose any. ● 6 pole width (Modulus 12.5mm), in line with JB/T7121-1993 standards. ● Optional 6 +1 digit (999999.1kWh, default) or 5 +2 bit display, by the user through the far infrared or RS485 communication port data set arbitrarily. ● standard pulse output passive (polarity), optional remote power pulse output passive (polarity), in line with IEC 62053-31 standard. ● equipped with a far-infrared data communication port and an RS485 data communication port, standard communication protocols conform DL/T645-1997 standard, you can choose other communication protocols. ● Three LED indicate power status and power pulse signal and data communication status. ● Standard configuration does not detect the load current direction of the trend, you can choose to automatically detect the direction of flow of load current by a single LED indicator. ● Single direction measure single phase two wire active energy consumption, independent of the load current direction of the trend, in line with standard IEC 62053-21. ● Standard configuration type S wiring (at the bottom line, top outlet), direct access to the formula used to select the access type using CT (Product Configuration code FC) and PT & CT connect operation (Product Configuration code EC). ● Standard configuration short terminals cover, may select extension terminals cover, protecting electrical safety (Product Configuration code GF).
