Electronic Technology Test-bed    Model:ETL-VA


    The design of the ETL series of electronic technology test-bed is based on experimental teaching demands in the books-Analog Electronics Technology and Digital Electronic Technology.Three models were made by the company`s research and development department according to the every school`s needs and recommendations to the devices.

    This equipment fully meets all the experimental contents and curriculum designs,as well as provide a good platform for teachers and graduate to develop new experiments or research works.

II.Features of Test-bed

1.Strong Science:With the development of subjects,electronics experimental content is gradually changing from a large number of verification experiments to the design of experiments,Comprehensive experiments.In spite of the face of conventional experimental content or a deeper level of teaching,the equipment is scientific and reasonable as well as avoids the equipment into a large and all-encompasing,resulting in a waste of funds.

2.Strong visualization:the clear pictures and reasonable panel layout and the "Plum Blossom From"design that are given a hand for the teachers and students` checking-line and will be very helpful to Train the students` manipulative ability.

3.Good reliability:silver-tube with the length of 2cm can be inserted in various components and there are more than 300 high-reliable locking-type anti-stack socket on the mother board. Wire are flexible contact with high reliability.

III.Technical Conditions


Work environment:temperature:-10°C~+40°C

                             Relative temperature≤ 85°C

                         Elevation≤ 4000meters

Equipment capacity:      ≤ 200VA
