Product Overview DDSH1599 multi-user energy meter is the use of microelectronics and surface mount technology production of intelligent products. The product uses single-chip processing system for data detection, sub-metering and display, small size, immunity to electromagnetic interference, low power consumption, long service life, the advantages of smart metering. This type of meter positive measure, no power-off function, cycle the power of information for each household, centralized installation, ease of installation, is mainly used for electricity metering new buildings, old buildings, student apartments. The product complies with JB / T10451-2004 and GB / T17215.321-2008 standards. Main Features 1, cycle through each household's electricity consumption, show clear and intuitive. 2, the case a metal forming, sealing, nice. 3, centralized installation, metering, easy installation, low cost of the project. 4, three-phase power supply circuit, even though the measurement can be normal phase. 5, using dedicated terminals, two bolt-pressure line, safe and reliable. 6, with infrared remote meter reading and meter reading computer networking capabilities. (User selectable) 7, the communication circuit design is stable, can effectively avoid signal interference caused by lightning and other factors. 8, with power display function, visually display the user's current electric power, easy on-site calibration. 9, which can measure and control 39 or 13 single-phase three-phase electricity users, with a three-phase power meter provides simultaneous output or single-phase power output. 10, high-precision current transformer, no heat during operation, good electrical isolation, strong overload capacity, life is strong.
