400+ end to end unique project solutions in wide areas of Electronics, Electrical, Embedded, Communication, IoT, Arduino and more.


The aim of this project is to develop a low voltage and high voltage tripping mechanism to protect the load from damage. The fluctuation in AC mains supply is frequent in homes and industries. The sensitive electronic devices in these conditions can get easily damaged. It is preferable to have a tripping mechanism to protect the load.

This proposed system will trip the load in the event of the input voltage falling below/above a set value. Two comparators are used as window comparator formed out of one quad comparator IC. This delivers an error output if the input voltage to them crosses the range beyond the voltage window. A relay is then operated to cutoff the load for safety reasons. A lamp is used as load in this project. It is extended by integrating an alarm, which sounds when the tripping takes place

 It can also be enhanced in future by interfacing with a GSM modem to convey alert message to the user via SMS to take appropriate action.

Q & A
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q:  What to do when the lamp fails and what is the maximum lamp rating that can be used?
A:  If the lamp fails one can use any lamp or bulb which is used in homes up to 100W. We suggest you to go for low watt bulbs.

I got to know about edgefx through google i was searching Over Voltage under protection in google then i got to know about edgefx.
I have decided to buy project edgefx because i found my project title in edgefx website that is why i have purchased project from edgefx. I like most about edgefx kit is kit Presentation.
support team has helped me purchasing the project & the kit was delivered in time with right components.
Provide advanced project projects for upcoming students & i want to give reference to my juniors.

I come to know about Edgefx through my senior. I decided to buy a kit from Edgefx through site because it is attractive and all the things were assembled clearly. I like the complete kit. Yes and I submitted my project in college and I completed my project successfully.No I directly purchased through online.No Improvements required.
