Product name

　　General electrical and electronic test bench

　　Model (Type)

　　BF-HY-18

　　Feature

　　The electrical and electronic laboratory equipment is suitable for colleges and universities, secondary schools, vocational schools, vocational and technical colleges and technical electrical engineering, electrical principles, electronic technology and other course experiments. It can complete circuit experiments such as AC and DC, oscillation, magnetic circuit circuit, operational amplifier, rectifier circuit, AC and DC amplifier circuit and digital logic circuit. This equipment is an ideal product for the replacement of existing laboratory equipment or for new construction and expansion of experimental equipment. Its equipment is an important symbol of the school's level and grade.

　　At present, most of the electrical and electronic experimental equipment of various schools in China are separated, and some schools have made various forms of experimental benches or experimental boxes according to the teaching requirements. The process is rough, the functions are incomplete, it cannot meet the experimental requirements, and it is prone to personal and equipment accidents, and the experimental components are difficult to purchase and manage. Based on this, our factory absorbs the advantages of similar products in Germany and China, and develops this product in combination with the requirements of my country's higher education and vocational education syllabus.
