MR175E Basic Electrical Training System Teaching Education Equipment For School Lab Electrical Automatic Trainer
This product is used in the training of electricians (including primary, intermediate and advanced electricians). The electrician's assessment cabinet uses lighting circuits. The actual operation of the electric control circuit of the electric motor is an indispensable skill training. It is also necessary for all levels of electrician practitioners. The content of the mastery is also the examination and appraisal content stipulated by the Ministry of Labor for “Electrical Technology Grade Standard” and “Electrical Operation Certificate”. The general electrician training appraisal and assessment device includes experiments and practical operations such as lighting circuit and electric drive control circuit. Wiring and other items. In order to cultivate students' basic skills and wiring skills in practice, the electrician laboratory cabinet greatly enriches the content of classroom internship teaching, improves the quality of internship teaching, and enables students to quickly master practical skills knowledge and practice wiring skills, so that training and internships can be made. The operation is moving to a new field, which is suitable for the teaching and skills training assessment of higher vocational colleges, higher vocational schools, secondary vocational schools and technical schools.
