Three Terminal Voltage Regulator with power supply and 2 meters (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12202
Indian Lab Suppliers supplies the Three Terminal Voltage Regulator with power supply and 2 meters (C.R.) (Product ID: 12202) as part of its electronics engineering lab equipment range. It is a training board on 78XX and 79XX three-terminal regulators, showing how a fixed regulator can be raised, made variable, current-boosted and paired for dual-polarity output.
Quick Answer
The board uses a 7805 and a 7905 fed from a built-in ±12 V DC, 500 mA unregulated supply. Experiments cover the effect of input and output capacitors, lifting the ground reference to raise the output, the minimum input-output differential (dropout) needed for regulation, load regulation, continuously variable output, an added PNP power transistor for higher current and two regulators for a dual-polarity output. A 0–1 A DC ammeter and a 0–20 V DC voltmeter (65 mm dials) are fitted; a 20 MHz oscilloscope is also required. It works from 230 V ±10%, 50 Hz mains.
