Technical Description
THGE-E1 is designed with concept of Competence Based Education (CBE). Signal generator, DC power supply and AC/DC instruments with excellent functions have been equipped, facilitating the experiments. The equipment adopts modular concept, which makes it possible to configure and further extend to satisfy individual requirements. Each unit is fully enclosed and the available mimic diagrams on front panel simplify the experimental connections. Safety has been paramount during the development of this equipment and every effort has been made to protect both the user and instruments.
