The DSS866 type DIN rail installation three-phase three-wire electronic watthour meter system I am using the advanced microelectronic technology and dedicated LSI, digital sampling technology and SMT process new technology developed by 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 three-phase AC power grid load active energy consumption. The table consists of seven LCD display function of power, good reliability, small size, light weight, beautiful appearance, easy installation. Wide range of applications and set up a complete and convenient 35mm DIN standard rail mounting, in line with the 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. ● 7-pole width (Modulus 17.5mm), in line with the DIN 43880 standard. 7-digit LCD display, standard 6 +1 (999999.1kWh), selectable 5 +2 bit display. ● standard pulse output passive (polarity), optional power pulse output passive distant ( polarity) to facilitate a variety of AMR system, in line with IEC 62053-31 and DIN 43864 standard. ● 6 LED indicates the relative power status (yellow, green, red) and energy pulse signal (white). Yellow COM RS485 communication instructions ● Standard configuration containing the detected load current trend direction, automatically detects the direction of the flow of load current by a separate LED indication. Single direction measurement phase three-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), direct access to the use of, access to use of the optional CT and PT & CT access use. ● Standard configuration short terminals cover, you can choose to extend terminals cover, to protect the safe use of electricity.
