Product Code : SCL-EELE-12213
Indian Lab Suppliers supplies the Variable Three Terminal Voltage Regulator with power supply and 2 meters (Product ID: 12213) as part of its electronics engineering lab equipment range. It is a self-contained training board for the parameters and applications of the LM317 adjustable three-terminal voltage regulator.
Quick Answer
Students measure load regulation and observe the short-circuit shutdown of the LM317, then build a 1.25–20 V variable regulator, a current-boosted regulator with an external PNP power transistor, short-circuit current limiting with an external transistor, and a 0–20 V variable regulator. A 25 V DC, 2 A unregulated supply feeds the regulator, and a separate –6 V DC, 100 mA supply allows the output to be taken down towards 0 V. Output is read on 3½-digit digital meters, 0–20 V and 0–2 A, with an electronic load and potentiometer on board, so no other apparatus is needed.
