DDS2 type of single-phase electronic energy meter (LCD) is to adapt to our single-phase electric metering requirements, design and development of the intellect Power Meter. The instrument was a high-tech products Commodities which used worlds most advanced ultra-low power consumption of mass ASIC technology and the SMT manufacturing. Selection of the key components of the internationally renowned brand long-life components, improving the products reliability and service life. Data shows that using long life and wide temperature range LCD, when power outages often display, which facilitate meter reading in blackout, with a higher degree of accuracy and reliability. The table also has infrared and 485 communications functions (choice) to facilitate the management of remote meter reading. Communication protocol support DL/T645-1997 "multi-functional electric energy meter communication protocol," offer the necessary for the automated management of the electricity conditions
