ETB-087 – Three Terminal Voltage Regulator with Power Supply and 2 Meters is a compact and effective training system designed to demonstrate the working and performance of three-terminal voltage regulator ICs such as LM317, 7805, 7812, and 7912. The trainer allows learners to study fixed and adjustable voltage regulation, understand regulation parameters like line and load regulation, and observe the thermal shutdown and current limiting features of these ICs. It includes a built-in regulated power supply and 2 precision meters to measure input/output voltage and current, making it ideal for analog and power electronics education.
Key Features:
Demonstrates working of popular three-terminal regulators (e.g., 7805, 7812, 7912, LM317)
Supports fixed and adjustable voltage regulation experiments
Built-in regulated power supply included
Two analog/digital meters for real-time voltage and current monitoring
Enables study of line regulation, load regulation, and dropout voltage
Clearly labeled front panel with accessible test points
