With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.


The project is designed to control AC power to a load by using firing angle control of thyristor. Efficiency of such power control is very high compared to any other method.

The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a pair of SCRs through opto isolator interface.

Finally the power is applied to the load through the SCRs in series. This project uses a microcontroller from 8051 family which is interfaced through a push button switch for increasing or decreasing the AC power to the load.

A lamp is used in place of an induction motor whose varying intensity demonstrates the varying power to the motor. The varying power results in variation in speed of the motor.

The project can be further enhanced by using direct 230 volt supply instead of 12 volt AC to the bridge rectifier for achieving higher voltage control for charging number of batteries in series.

Easy to use, Self-explanatory kit.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin 8051 microcontroller is used in this project.
Q:  What is thyristor AC power control?
A:  By using push button provided, we can control the power to the load. This can also be done with Bluetooth see model no 325. Follow the link: http://www.edgefxkits.in/remote-ac-power-control-by-android-application-with-lcd-display
Q:  Can I place motor instead of lamp?
A:  Yes motor with rating, up to ¼HP 230V AC, can be placed instead on lamp.
Q:  How is the bulb intensity varied?
A:  The bulb intensity can be varied by delaying the firing angle of Thyristor, so as to control its triggering.

I come to know about Edgefx through Internet and Last year even my friends taken the project from Edgfx. I used the keyword- electronics projects to find Edgefx in Google.I decided to buy a kit from Edgefx because price is reasonable and finishing looks like reliable.No my kit delayed for a day.One of your Executive helped me while purchasing the project.Delivery should be in time.

I come to know about Edgefx through Internet. I used Btech projects for final year as a keyword in Google.I decided because it is reasonable, quick delivery and nearest distance.The kit delayed for two hours.Ms. Suvarna replied to my call and I placed an order through her guidance.Improvements should be in the Project description and overview.

I came to know about Edgefx through Google while I and my friends were searching for the projects and we used projects as a keyword in Google to find Edgefx.I decided to buy a kit because of the Delivery facility. I like the complete kit.Yes the kit delivered on time with the right components.I purchased the project through online.No Improvements required.

I decided to buy a kit from Edgefx because we get the components and kit which we want for our project.The way the audio-visuals are explained in the project and its knowledge is so special. It was a great learning experience to build the project.
