Two Input Nand Gate

This panel is used to demonstrate the number systems such as binary, decimal and hexadecimal numbers. Toggle switches used to activate the displays showing the particular number entered. Input may be entered either as decimal or binary numbers with a toggle switch for mode selection. Decimal numbers are shown on a three digit seven segment LED display. 12 V / 2 A DC adaptor is required to operate it.

Diode mounted on transparent covered base for maximum visibility to students. Two four mm sockets one red and one black are provided for easy connections.

Logic Gates Trainer has been designed to study logic gates and applications. This trainer board is designed to verify the truth table of various logic functions, to prove De-Morgan’s theorem, Half adder and Full adder by using logic gates. The board is absolutely self-contained and requires no additional apparatus. 12 V / 1 A DC adaptor is required to operate it.

Bridge rectifier is designed with four LED’s internally arranged in bridge pattern fitted inside a plastic moulded case. Two LED’s are red and two LED’s are green. This device is used to demonstrate the functioning of a bridge rectifier, i.e., to convert alternating current (AC) into direct current (DC). Two yellow sockets are used for AC input. Two sockets, one red and one black, are used for DC output. For the easy understanding of the internal circuitry, the circuit diagram is printed on the box.
