Study of Voltage and Current Regulated Power Supplies (C.R.) Manufacturer,Supplier and Exporter in India

Product Code : SCL-EELE-12219

Indian Lab Suppliers supplies the Study of Voltage and Current Regulated Power Supplies (C.R.) (Product ID: 12219) as part of its electronics engineering lab equipment range. It is a self-contained board that contrasts voltage-regulated and current-regulated power supply circuits.

Quick Answer

Voltage regulators studied are a Zener shunt regulator, a series-pass transistor regulator and an IC regulator. Current regulators include a transistor current source referenced by a Zener diode, silicon diodes or an LED, and an IC current regulator. A mains transformer gives 9 and 14 V AC tappings at 150 mA; a DC milliammeter (1, 10 and 100 mA) and a 0–30 V DC voltmeter record how output voltage and current respond to load changes. The board carries a voltage regulator IC, NPN transistor and Zener diode, and needs no other apparatus.

Frequently Asked Questions

What is the difference studied?
A voltage regulator holds output voltage steady; a current regulator holds output current steady as load changes.

Which references are used for the current source?
A Zener diode, silicon diodes or an LED.

Is extra apparatus needed?
No, the board is self-contained.
