LAB modular electronics training system package redefines Hands-On Teaching and learning. This modular package is supplied with Mother module and various experimental modules in each topic covering all important principles and experiments related to that particular topic. In each topic we supply minimum of 5 experimental modules and maximum of 35 modules depending upon the topic. These experimental modules are designed using most modern CAD tools with circuit diagram neatly printed in Multi-Colors for easy identification and fixed components like resistors, capacitors, inductors. Transistors are soldered on the back of the PCB so that students are not allowed to tamper with the components. Variable components like Potentiometers, Gang-condensers, Trim-pots and ICs are mounted on top of the modules for the students to take measurements. These modules are pre-assembled so that students do not waste time in the laboratory in search of components and more number of experiments can be conducted in a given time frame. But, you are not restricted to using only the experiments provided. With this modular trainer flexibility and your imagination, any number of experiments is possible. Components are well placed to provide students with a clear, uncluttered view of each component and circuitry with plenty of room to make measurements.

WHAT IS MODULAR TRAINING SYSTEM?
Modular training system comes with a set of mother module and experimental modules. Mother module is provided with necessary power supplies, signal sources, input switches, output lamps, terminals, and 7-segment displays. Experimental modules can be slided into the mother module and all necessary power supplies, signal sources, inputs and outputs can be drawn from the mother module to the experimental modules. The student can start conducting the experiments one by one with the help of instruction Manual. This helps the student to go about doing the experiment in a programmed way.

This modular trainer offers students a unique approach to learning about electronics, and an innovative approach to the electronics revolution.

MODULAR TRAINERS PROVIDE THE ROAD MAP TO SUCCESS These experimental modules are uniquely patterned. Students can establishing the relationship between cause (input) and the Effect (output). Experimental modules are provided in such a way that the learning process is gradual and quick.

ABOUT MODULAR RACK MOUNTING SYSTEM

Modular training system has a rugged rack mounting tray to protect all the experimental modules along with its accessories. Experimental modules slide into the slotted partitions and the parts tray rest on top. This is a great way for your instructor, to keep track of modules and parts. The durable tray prevents damage and provides you with a completely mobile experiment package.

The parts tray holds additional experiment parts and jumper wires. Different lengths of wires are provided.
