Однофазный Elecrical Вт-час метр

Application DDS238 single phase electrical watt-hour meter adopt a large scale of integrated circuits and SMT technology, whole screen and anti-jamming structure, its technical performance are completely conform to national standard GB/T 17215-2002 and international standard IEC62053.The meter has the following features: (1)High reliability, low power loss, high accuracy, wide load capacity. (2)Can accurately measure active energy power from positive direction and negative direction, and accumulative total in the same direction, and has function of anti-stealing electricity. (3) adopt photo-electricity coupling no power pulse output, and indication using electricity by LED, and can realize collecting reading meter so as to control using electricity and management. It is used for measuring active energy power loss in frequency 50 Hz or 60 Hz single phase AC electricity net and which is installed in meter box indoors or outdoors. Technical parameters Type
