How to make short circuit protection Relay | For Power Supply

Ғылым және технология

hello friends
wellcome to my channel creative for you
in this video i will make a simple relay short circuit protection using a 12V relay this circuit is very useful and easy to make
this works for 12V of you use 12V relay but you can't lower then 9V but if you use 5V or 6V relay then you can use it for 4.2V Lithium ion battery to prevent short circuit this is best for Bigenner who Don't have lab power supply so they cant set current limit this circuit can handle 2A without triggering the protection this circuit works great for lead acid battery This circuit can be used as a power supply protection unit manual reset
what is Short circuit??
A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.

    Hey good sir, thanks for sharing this. I still got my doubts so, may i ask you a few questions? I really want to know what is the maximum current this circuit can handle, i read down in the comment section that it depends on the relay current. So if i use a 24 volts / 5 amps relay, it will trigger at 5 amps (or so)?

    If you use 24V 5A relay it will give 5A .but however the current protection will be not trigger by drowing current . if you short the output then the protection works.

    Hi, friend. Good idea, let me ask you a question.Can we know why the whole thing works if we connect several in parallel (voltage sharing) and short one?What I want is to connect 20 of them in parallel and use them for each circuit.

    😊 IT WORKS BUT This can be used with Motors / Led ... But if you use it for Sensitive electronic like Andruno or something .. That can damage it because . there are Unwanted Oscillation of relay and the relay create voltage spike easily ... AND JUST USE A BIGGER RELAY FOR Higher CURRENT not need to use 20 of them 🤗

    The relay switches off AFTER and because the power supply has been overloaded already.Try this with a car starter battery, and it will burn your relay or the cables. Press the button while the output is shortened, it will destroy the button. Try this with an unprotected AC adapter, it will destroy the adapter. Try this with a protected AC adapter and ask yourself if you need this relay. The button is not suitable for 10A.

    Sims like all the problems about output supply voltage protection are solved with a so simple cirquit... but no... for those who don't understand the cirquit , when the short cut happends we are making a short curt in the power supply, not only in the relay, so, the voltage drops and make an instability in the supply of the relay to keep active and cut it, this is what makes the protection, but if the power supply don't have an protection inself against short cuts in her output we have a big problem, or, if the power supply have an protection , charges up to 1 ampere can make sparks in the relay contacts that can with time or dependin on the load, in the firs short cut burn the relay contacts an fix the contacts soldering them becouse of the soark, making the turn off of the relay impossible and create an short cut ininterupt, what may cause damages to the cirquits verry bad, risk of fire or something like this. I think that less than 500ma and 9 volts of charge maximum it's safe, more than that is verry dangerous. And make shure that your power supply have an protection for the short cut that this cirquit will cause in the protection mode.
