SALIENT FEATURES :
ADTRON’S Transistorised PWM Inverter is a self contained stand alone unit useful in the study and demonstration of the principle and working of a Transistorised PWM Inverter. It consists of a DC Source, UJT triggering Circuit of variable frequency and AC output. The load capacity of the Inverter is 500 VA. 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.
