DDS175 (L) Однофазный электронный счетчик Общие

Product Overview DDS175 (L) single phase common electronicl meters are the new electric power measuring meters produced by adopting dedicated measurement circuits, high-performance electronic components and advanced SMT technology, based on high-precision voltage, current detection and digital signal processing principles to achieve energy measurement. That can be widely used in single phase AC electric power grid measurement. Main Features High measuring accuracy, load range, start with high sensitivity, low power consumption, anti-submarine action, anti-theft, small size and light weight. Display: register LCD display Communication interface: RS-485 (LCD display) the initial interface communication speed is set to 2400bps. 38 KHz infrared modulation (LCD display) interface communication rate defaults to 1200bps. Can read the current combination active, the current being active, curren reverse active, combination active =active + reverse active. Can set the table number and 02, 04-level password. Can clear the meter base degree.
