Class A, B, C & AB Amplifier with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12315
Indian Lab Suppliers supplies the Class A, B, C & AB Amplifier with Power Supply (Product ID: 12315) as part of its electronics engineering lab equipment range. It shows how biasing sets class A, class B, class C and class AB operation of a transistor amplifier.
Quick Answer
An NPN transistor stage is driven by a built-in 1 kHz sine-wave oscillator, and two potentiometers set the positive and negative bias voltages. Moving the bias changes the conduction angle: the full 360° cycle in class A, about 180° in class B, between 180° and 360° in class AB and well under 180° in class C. Students compare input and output on a dual-trace 20 MHz CRO, the only extra item required. The oscillator output is given as both 1.5 V p-p and 2 V p-p, so please confirm the signal level at quotation. Power comes from an internal ±12 V DC, 100 mA supply.
