DC Current Protection Project | OverLoad and Over Current | Short Circuit Protect
I Hope you like it.
All electric component you can buy from: utsource.net?source=TH-cam
Everything shared to you has been fixed. Input from 0-100VDC Current can handle to 30A. It's using 12V for control board from another small module PSU.I hope you like my project, watch video to the end for more detail
Protect current can setting by adjust VR. Clockwise to more current.if current of load lower than current setting everything is normally.if current of load biger than current setting, the circuit will working and cut off output immediately until we push the button to RESET.
I hope you can donate me some money for i can buy electronics component to make new video with high quality.

Hi i made this working like a charm...... many thanks buddy.... i have taken your milling pcb layout and etched and welded all component. It worked well.
This is my long awaited circuit I was looking for thanks for this project. Kindly make variable power supply up to 15/20 amps I need eagerly
Hope you like it
Good project 👍
Thank
Thanks brader ..
Very good
Thank you
Superb works sir
Thanks
Super sir. ❣️
Hello my friend
Your protection circuit works great and I thank you for your good work.
I built this circuit and it works properly but one thing about the operation of this circuit occupies my mind
and that is that when I connect a device like a motor to it and the circuit allows the required current to pass through it
and when The motor is in load mode and consumes more current, the circuit does not react, ie it does not cut off the current.
You previously posted a video on 1/15/2018 about the performance of a protection circuit, which, although that circuit had some problems,
but when you tested it with a motor, the protection circuit reacted well to the increase of the motor tensile current, and He cut off the flow.
I want to know why the new protection circuit does not have this feature?
I hope I have stated what I mean correctly
Thanks a lot.
Still wandering why such a great channel has just few thousands subscribers
Me too
Hello. excellent. You have had little activity in your channel for some time. You usually put one project a week. I hope it is like this again.
Thank you, i will try to do that
La he ajustado hasta en 7A y actúa bien, pero en más corriente no. La he seteado en 8A, 10A y al momento de añadir carga o subir tensión, la corriente llega a 15A y aún no protege.
Lo que tengo para decir de diferente es que le dí 6 vueltas de alambre (como en el video anterior), así que intentaré dándole 11 vueltas a ver que cambia.
👍👍
Hello...
Thanks for your usefull project
Sadly i can not order the PCB from this site and i have to print it on paper and stick on the board manualy
Can you share the pcb board map like previews video?
Hai long.. please make a soft start using two 12v 30a relays with ntc 4x20d20 plus 2 temperature sensors ... for a 5000 watt amplifier
Con corrientes superiores a 6A el ajuste comienza a ser impreciso debido a que el pin#6 queda ajustado en (ej) 3V con el potenciómetro y al aumentar la carga a la salida, va aumentando la tensión en el pin#5 pero llega hasta 2.8V y no aumenta más, por más que le añada 20A de carga, al contrario una vez llegado a esos 2.8V, comienza luego a descender y la protección nunca actúa.
Creería que es algún problema relacionado a los divisores, pero aún no lo sé.
Saludos!
Superb sir.... Shall i use 0.1 ohm 5w resistor instead of that magnetic wire?? Pls replay
Nice
Please make a SMPS for T12 soldering station with using old computer psu transformer. 24V 3A or 19V 3A.
I will

Thank you for your reply ♥️
Buenos días, excelente idea. Podrías compartir el diagrama esquemático. Saludos

Can i use 12v for control voltage??
Hi how to make it Auto rest without switch pressing.
Chào bác. Cái inverter sine 1000w trong clip của bác á. E dùng 4 con igbt 30a600v. Áp dc 380v. Tụ lọc 120v. Áp ac ra 225v. Sao e tải gần 200w nó còn 150v là egs ngắt luôn. Có cách nào khắc phục cho áp ko bị tụt nặng ko bác
Its ok, but when it comes to transistors... sometimes its too slow to protect a transistor from short circuit. It takes several miliseconds to activate.
Thanks
can this circuit work for smps power supply?
Hello i bought a bench power supply that does not have short circuit protect and i cant control the current output. Can i modify it with ur project ?
Can you please send the offer for this board with soldered components. As you have tested this and its working can you please send me the price.
hi can you share pcb layout as e cannot order from jlpcb in india.please share otherwise its useless to me.
bro, your GerberFiles is incorrect . please check again pin no.1 of LM358 is connected to GND
ask for help to curate a PDF format file for manual printing thanks
Inductors details
ask for a laser jet printer pdf layout on yutube the gerber file can't be opened please help tkn's...👍👍👍
hello friend..please send us the pdf file for experimentation with laserjet printer printing
Hallo sir
I want to visit "American electronic channel " ......Is it possible...??
Yaar circuit digram proper de doo
This PCB have mistake!
Only short circuit not overload
This is fake
