Project 11/17/17 TPS

Triple Power Supply Project

A must have in any laboratory, on a test bench, or for experimentation. This power supply is 3 variable power supplies in one unit. It features ±1VDC to ±15VDC at 2 Amps and 5VDC up to 5 Amps. 

Student learn the basics of linear voltage regulators (LM317/LM337), 16x2 Parallel loading LCD screens controlled by Arduino, bread-boarding, PCB design as well as custom enclosure design using our Epilog M2 laser cutter.

Also cover in this project is OPAMP signal conditioning using a LM324, Buffers, Inverting Amps and Dividers. Scaling, A2D conversion and math functions of the Arduino.
