INDUSTRIAL PROJECT

1. Project title: SMPS

Project description:

In this project,design the 15 wattage fly back topology SMPS with 12 volt output for universal input range(85-275v AC ).Also included that some more protection features like short circuit,open circuit, under load and over load protections.

2. Project title: SMPS

Project description:

In this project,design the 25 wattage fly back topology SMPS with 24 volt output for universal input range(85-275v AC ).Also included that some more protection features like short circuit,open circuit and over load protections. 3. Project title: Load cell Weighing indicator and controller. Project Description:

The objective of the project is to observe the changes in load cell and show the corresponding weight .Strain gauge load cells convert the load acting on them into electrical signals. Weight and relay setting values are monitored by PIC16F887 micro controller, its displayed by using seven segment displays.

4. Project title: Temperature controller.

Project Description:

The objective of the project is to monitoring the temperature changes and maintain at constant temperature, its achieved by using temperature sensors like thermocouple and RTD (PT-100), displaying with help of 7 segment display.
