Regulated Power Supplies Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12142
Indian Lab Suppliers supplies the Regulated Power Supplies (Product ID: 12142) as part of its electronics engineering lab equipment range. It is a training board covering rectifiers, filters and transistor voltage regulators, ending with a 0–9 V variable regulated DC supply.
Quick Answer
The board provides a 9 V AC, 300 mA supply, a 0–200 mA electronic load, three NPN and one PNP transistor (one of them a power transistor), 4 diodes, 3 Zener diodes, 2 potentiometers and an inductor. Students study half-wave and full-wave rectification; ripple with capacitor, inductor, choke-input LC and CLC (π) filters; Zener, series, error-feedback series, Darlington-pass and shunt regulators with current limiting; and measure line regulation, load regulation and ripple factor of the 0–9 V variable supply.

Where This Is Used
Used in power supply and analog electronics practicals; the rectifier section pairs with the Junction Diode Rectifier & Filter Characteristics with power supply and 2 meters (Product ID: 12195). A variac is used to vary the mains for line-regulation tests, so it must be earthed and handled under supervision.
