Our company uses microelectronic technology to measure electrical energy, using imported specialized large-scale integrated circuits and advanced technologies such as digital sampling and processing technology and SMT technology to develop a new type of three item all-purpose electronic energy meter. This electric energy meter fully complies with the relevant technical requirements of the national standard GB/T17215.321-2008 and the international standard IEC62053-21 for Class 1, 0.5S, and 0.2S three-phase active energy meters; It can be equipped with power outage display and backlight, displaying total active power, total reactive power, current, voltage, power, power factor, compound rate, time interval measurement, and reverse measurement. The total power consumption is displayed by a 6+2-bit LCD LCD, with communication protocol DL/645-2007 or MODBUS-RTU optional. It has the characteristics of good reliability, small size, light weight, beautiful appearance, advanced technology, and 35mm DIN standard rail installation. It also has good electromagnetic interference resistance, low power consumption, high accuracy, high overload, high stability, anti theft, and long service life.
