Crystal tube DC speed adjustment training device

 

The device uses a universal small -capacity crystal tube DC speed regulating circuit. The m--n circuit is a single -phase bridge semi -control structure. The system uses voltage negative feedback and current positive feedback control, and has a current off -departure feedback link and series micro -branch correction network. This device is in line with the "Career Standards" and the "Tr--ning Equipment Industry Standards" issued by the Ministry of Labor and Social Security of the People's Republic of China, which is suitable for various secondary vocational and technical schools. Labor tr--ning and skill appr--sal units' teaching and tr--ning and m--ntenance of electricity in the middle/** practical assessment and skill appr--sal of electricians.

 

This device has a expansion interface, leakage protection, and special fault setting box. It can make its own unit constitute a single -closed rim with a static and DC speed regulating control system. The fault point can be randomly set according to the requirements of teaching and assessment.
