The ETB-199 is a comprehensive trainer designed to demonstrate and compare Zener diode-based voltage regulation and IC-regulated power supply systems. This model is ideal for foundational electronics training, helping students understand the concepts of voltage regulation, load regulation, and ripple rejection using both traditional and modern regulator circuits.
The trainer includes:
Zener diode regulation section
Fixed and adjustable IC voltage regulators (e.g., 7805, 7812, LM317)
Built-in variable DC power supply
Digital meters for voltage/current measurement
Clearly marked test points and circuit block diagrams
It is perfect for use in analog electronics labs, providing hands-on learning of linear regulation techniques, performance evaluation of regulators, and real-world circuit behavior under varying load conditions.
