About us:
WUHAN SANFRAN ELECTRONICS CO., LTD. is a professional supplier of water, electricity, gas, heat and energy efficiency management solution which was founded in 1998, and covers an area of about 133,400 square meters. 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, and the qualified rate has reached above 99.95% in the last two years.
Under the development concept of "Energy-saving, Green, Innovation", 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 company invests nearly 50 million yuan in scientific research every year, establishes a CNAS laboratory to develop various products, and has obtained more than 200 national patents and software copyrights(including more than 35 invention patents). The low-power energy meter developed by SANFRAN reduces the power consumption of single phase energy meters to 0.25W and the power consumption of three phase energy meters to 0.15W (both are about 45% of the power consumption of similar electric energy meters). And this single phase integrated smart prepayment meter project with low-power consumption based on switching mode power supply won the 21st Nation Invention Gold Award in 2015, it was also awarded with "Climate Solver" by WWF in 2014.
