Power Supply Trainer For Electrical Lab Training

The power supply trainer is a comprehensive training system for the laboratories. It is useful in understanding the various concepts of a DC power supply. As we know that power supply is a very basic element of any electronic circuit or appliance. Starting from a mobile charger to a huge Computer system, each needs an efficient power supply. It is essential for an engineer to know basic concepts of electronic power supplies. This trainer describes the transformer, rectifiers, filters, regulators, role of bleeder resistor, load and line regulation etc. While performing any experiment students have to connect the links by patch cords so it is very helpful for students to learn the inputs and outputs of different sections of any power supply circuit. It also consists of a demonstration bridge which is made up of LEDs for visualization of each part of an AC cycle. Real time appearance of components Test points are provided in different sections of power supply Demonstration bridge Designed by considering all the safety standards Provided with a detailed Operating manual Low cost yet including many experiments 2 Years Warranty Technical Specifications Input : 230 V ±10%, 50 Hz Outputs Zener diode outputs : 10 V, 5.6 V regulated Regulators outputs :  +12 V regulated -12 V regulated 1.8 to 17 V adjustable Load : 5 K variable with 1 K fixed resistance.
