Step DOWN Transistorised Chopper Trainer

SKU: 8534 Category:

SALIENT FEATURES :

Step Down Transistorised Chopper is a self contained stand alone unit useful in the study and demonstration of the principle and working of a Transistorised Step Down Chopper. It consists of a DC Source, Control Circuit (Firing Circuit), Power Circuit and DC output. The DC Output drives a bulb load. The unit is housed in an elegant metal cabinet, with a well spread intelligently designed circuit layout on the front panel. Multicoloured Test Points are provided at various stages in the circuit to observe the waveforms and voltages. It is strongly supported by a comprehensive Instruction Manual complete with theory and operating details.
