makes a current cut. when I turn on the car key. after a few seconds. The car turns off and only turns on when I press the button. you can do? ?

Up

Ppp

My uncle built his own pc back in the day with RadioShack parts.. I wish I had of taken the time to learn some of it from him, the guy was genius at it.. I'm a genius too, but I didn't get into circuitry and electronics. Not like you or he did.

😊😊😊ppp

Yes😊

Ever heard of fuses?

Can this be done at higher volts of like 36, 48 or even 60? I gonna be stuck between 30 to 50 amps from 12 volt is insufficient wattage(do volts x amps). 12 x 50 = 600 watts for constant flow in dc, however 36 x 50 = 1,800 watts. More energy flowing through circuit. I just need higher volts due to many applications that could use higher volts in place of lower volts for more control and isolation. 12 volt is dedicated signals, so no random spikes in draw allowed on it. However the higher volt system can accommodate the extra volts just to be able to withstand higher load.

So have you ever heard of fuse? You can choose different current rating of fuse, so you know

@@fruitieplayys9125 fuses won’t work. Has to be a circuit breaker like this. The fuse won’t react fast enough to high loads.

Do you think the algorithm learned to only show this a night ? I only get videos from this channel after sunset ...

I too

True, thought the same thing

It only works if your Power supply is high impedance though. Otherwise you just fry everything. Imagine 100 A going through that relay

@@jor7137 IIRC The relay is ~100 ohms.

@@ABehrooz Sorry, I meant the relay contacts, not the relay coil. Should have been more specific.

educational good video thanks.

Hi! What happens if you press the button with the shortcircuit?

Yeah, what happens?

@@chiapetYT Fire lol

​@@andrenz2000short circuit. Defeating the purpose of the circuit.

I guess high current would pass through the button and probably burn it. I think you can add a resistor in series with the button to limit the current in that case.

Hello. Can you tell me the output amps, of you'r power source? My Power suply is 18V/10 A, and I wonder if this circuit rezist at 10A.Ths

@@elendil399 mine supplies 18v3A at safe range and 6A max load current however I haven't tried drawing 6A continuously, but you can use 12v 30A relay that can be found at any automobile spare parts shop...

Thank you.

How did you make it 3v to 18v?

@@ziakhan1841 I think I should explain it in a video.

Hehe. In other words, only use it where it isn't required :-)

​@@colinstamp9053jajaja

and why is that?!? the "short" is just on the motor, not on the battery. Check the circuit!

@@robegatt The supply/battery is connected directly (via the relay contacts) to the motor when the relay is active. This means that the short circuit current must be disconnected by the relay contacts when the circuit trips. Also, if the switch is pressed to reactivate when the short is still there, the short circuit current will go thru the switch. So, the short circuit current should be limited to what both the switch and the relay can handle. With a current limit on the supply, the circuit can be useful.

@@robegatt Nope. The circuit relies on the incoming supply collapsing below the relay's holding voltage. The circuit does have a use, but not as short-circuit protection. It's actually a "no volt release" switch. They're used, for example, to prevent motors unexpectedly re-starting after a temporary break in the incoming supply.

I'm more of a programmer, but it seems like that to me too

It's a non latching relay. If you cut power it will switch back.

Not a latching relay

I should have said latching relay CIRCUIT and not.implied latching TYPE relay.

It doesn't make any sense in my head, either a relay is latching or it isn't. It is activated when power is on, not activated when power is off. But I could be wrong.

That's your concern? not the fact that this circuit has a slow reaction time, the fact that the trigger current can not be set and that the trigger current will also depend on the output impedance of the power supply and cables? man.. this circuit has so many issues

@@jochemvandolder5046 What’s your point, pal? Criticizing me for not criticizing for good reasons? I mention some flaws, you mention some other. Read the last sentence of my previous comment. It’s a bad design. We’re on the same page bro.

*Battle of the brains*

You are absolutely right. This circuit is a complete nonsense. It depends on the fact that, in case of a short circuit, the voltage drops, releasing the relay, so the real protection depends on the power supply.

​@@peraperic5270 Why one the relay coils supply terminal is shorted to NO terminal? When the coil is powered the common terminal is energized and touches NO, what is the purpose of short circuiting ?

1. Небольшая. 2. Любой механический предмет имеет срок службы.

Короткое замыкание - аварийный режим работы. Не надо путать с постоянным. А вообще надо через ограничительный резистор все это включать. Тогда меньше будет пиковый ток кз.

На контакты припаять искрогасяшую цепочку RC и продлит жизнь контактам на долго.

Tbh I think it’s going to blow up like a capacitor

Also at 200A

What is it called again?

Ну, в КЗ он находится только до момента перекидки якоря реле; миллисекунды. А если последовательно , ПЕРЕД релюшкой, в цепь питания включить дроссель, то вообще проблемы не будет. И цепи питания обмоток (их две) релюшки, сто'ит настраивать не на КЗ, а на недопустимый ток перегрузки; КЗ в этом случае, сработает тем-более.

I am also electronics engineering student

Kaha se ho aap

Depends upon relay... I used 10A relay and its working till yet (about 5 months) without any issue

It depends on the spring on relay. At 20A and above, it is powerful enough to weld the contactors inside the relay and most of the time the spring is not strong enough to make the circuit open again. As a result, it will short indefinitely.

@@troyguererro0898 and the best choice is to use a relay with bimetallic spring that automatically breaks contact as the temperature rises...

It keeps the relay on by supplying current to the coii

​@@kelumprasanna6177 thx, now I understand how this works

Just use a bigger resistor and respectively rated relay.
