DDS228 rail-mounted single-phase electronic active energy meter Emil electronic technology company using microelectronic technology has dedicated LSI, application of digital sampling technology and SMT technology and other advanced technologies developed completely independent intellectual property rights of single-phase two line power meter. The table technical performance in full compliance with international standard IEC 62053-21 relevant technical requirements of a single-phase active energy meter can accurately and directly measure active energy rated frequency of 50Hz or 60Hz single phase AC electricity net 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, Features ● 35mm DIN standard rail installation, complying with DIN EN 50022 standard, or the plate before mounting (mounting holes center distance 63 mm), two installation arbitrarily selected by the user. ● 6 pole width (modulo 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 is not detecting a load current flow direction, 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 standard IEC 62053-21. ● 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 connect operation PT & CT (Product Configuration code EC). ● Standard configuration short terminals cover, optional extended terminals cover to protect electrical safety (Product Configuration code GF). 18879978399
