Magnetic Amplifier Trainer

SKU: 2012 Category:


Magnetic Amplifier is a versatile self contained stand alone unit useful in the study and demonstration of the principle and working of a magnetic amplifier. It consists of saturable reactors, various windings, rectifiers. Here the load current is controlled by magnetic property, which in turn depends upon DC control current. Various experiments listed below can be performed. The unit is housed in a specially designed layout on front panel. It is strongly supported by a comprehensive instruction manual complete with theory and operating details.
