Company introduction:
WUHAN SANFRAN ELECTRONICS CO.,LTD. is a professional manufacturer and supplier of water, electricity, gas, heat and energy efficiency management solution which was founded in 1998. The company covers an area of about 30 acres, 3,000 square meters of factory buildings have been built, main products including: electric energy meter, water meter, gas meter and management platform. In 2014, it was assessed as the key high-tech enterprise of National Torch Plan. In the recent tenders of power grid, the company's total number of winning bids ranked in the top eight. The amount of annual order reaches 700 million RMB. After-sales service agencies cover 31 provinces and cities.
Under the business philosophy of "Focus, Innovation, Quality, Fair and Competent ", SANFRAN has been committed to researching solutions for smart energy meters and the extended products for more than 20 years, and has successively developed more than 100 kinds of smart energy meter with low-power consumption, long lifetime, multi-mode communication. The low-power consumption energy meter developed by SANFRAN reduced the power consumption of single-phase energy meters to 0.25W, three-phase energy meters to 0.15W (both are about 45% of the power consumption among similar electric energy meters). Since 2009, there were more than 30,000,000 low-power consumption meters running which save a lot of energy for the country. The company has accumulated to obtain national patents and software copyrights more than 200 items(including more than 35 invention patents). The single phase integrated smart prepayment meter project with low-power consumption based on switching mode power supply won the 21^st Nation Invention Gold Award in 2015. And because of this, it was awarded with "Climate Solver" by WWF in 2014. There are only five companies to receive this honor. Starting from 2018, the key research direction of SANFRAN focus on the further application of big data of smart energy meter.
