I live in Japan and do various crafts. I do a lot of DIY as a hobby.
At first glance, it's a simple circuit, but it's highly functional! The three-dimensional wiring is wonderful too!
thank u for visit
Hi. Can you make a vlog regarding a heavy duty circuit just same as this pls... Thanks
Nice work. (Kindly, a small ~dark filter on the voltmeter LED would help to better distinguish the numbers. Just my humble input). Thank you for making & posting this video. 🙂
All details in the video
Is this regulator circuit is work well after short circuit accidentally?
What is the function of bd139 in this circuit? Thank you.
very nice and excellent job.
❤️
Rj edit all you're the best👍
Thank u very much for your compliments ❤️
Hello, congratulations for the project you have done, I had a question. The purpose of using thick copper tal in this project is to remove the current or if we use a standard cable, will it be a problem?
No problem
Thanks and God bless 🙌
Always happy n healthy
Brother. this is really good!
Thanks for listening
Добрый вечер!
Супер!
Thank u ❤️
I made this your voltage control circuit. it is working well friend. mosfets were heat in hurry. and thank you very much about your project . what did you add diode ampere please?
U are most welcome for comments, 2-3 ampere you can use
@@RJEDITALL yes my friend I used 5408 for it. thank you for your reply. all the best 👍👍👍👍👍👍👍👍👍.
Keep your spirit from Indonesia
Welcome to my Channel, always happy n healthy
Gracias por el aporte solo tengo una inquietud, en la descripción del vídeo dices que el circuito es de 0-50 y de 0 a 20 amperios pero en el diagrama que muestras al final del vídeo dices que de 3 a 30 voltios y de 1 a 20 amperios gracias
Yes, you use 6 transistor for 50v dc
Son solo inconsistencias, si estos proyectos se usaran en astronomia, esta serviría solo para juegos pirotécnicos.
Como tiene input de 10 amp y proporciona 20 amp?
Son 10 que regala el buen circuito
To 50v the lm317 needs to have a suffix HVT see the datasheet lm317hvt it can handle 60V while the lm317t just 38V
nice 👍
❤️💝
Buenas tardes un saludo desde venezuela. Primeramente mis felicitaciones por su prollecto muy entendido y facil de hacer exitos en sus demas proyecto que dios le siga dando mas sabiduria e inteleigencia. Bueno amigo mi pregunta es la sigue te ! Si toca las 2 puntas de la salida se quemaria el circuito o alguno de los transistores ? Ya que no le veo un sistema de protecion contra cortocircuito es lo unico que le aria falta a este proyecto espero su respuesta gracias buen dia exitos en sus proyectos...
Use this power supply with short circuit protection 👇

Hello thank you very much for this video. You seem to have left out one part which I think is a resistor at 2:44. What is it?
Please check diagram in the video
Like your video might do this at home, may I ask can I still supply a phone when using that? And is there a current protection?
Please connect at output side 3 ampere diode for protection
@@RJEDITALLokay thanks, my other question can I still supply/charge my phone using by doing this schematic? Cuz I built a lps the lm317t is overheating when I supply my phone
tôi rất thích các video của bạn
Thank you bro 👍

Na narysowanym schemacie nie ma oznaczeń wyprowadzeń tranzystorów. ( E?, B? ,C?)???
Un circuito regulador de 24v 120A tendras... 😬y en vez del 3055 se le podria poner mosfet´s de 120A...?'?🤔
??
If you have 2 digital meter I think it good to see .
Спасибо мне нравятся ваши схемы. Они не дорогие по буджету зато работают. Одна просьба к вам. Когда публикуете схему она очень короткая по времени экспозиции. Её трудно выделить на стоп каде. Увелисте время просмотра схемы до 3-4 секунды. Заранее благодарю.
Ok bro, u are most welcome ❤️
Я сам эту схему собрал и вот что скажу,по напряжения сильно просаживается на 3 или 5вольт,хоть 30вольт выдаёшь на вход после диодного моста и канденсатора,на выходе сильно просаживается,ну например ставим 12вольт и подключаешь 12вольтовый лампу 21ватт по напряжения до 9вольт просаживается,а если 12в 60ватт подключить он вообще сильно просядит до 5 или 4вольт просаживается,хоть по току на максимально стоит,по напряжения и по току работает,но по напряжения сильно просаживается.
а Вы попробуйте умножить 1 Ом на квадрат половины вых. тока ( через один 3055 )........... ого, 100 Ватт на 5-и ваттке ! а падение,... ого - до 10-и вольт, при вых токе 20 А ! Это не схема, это говно. Даже если исправить ошибку и вместо 1 Ома ???? применить 0,1 Ома !!!!!
@@alexgonchar3907 а если без 5ватт резистор будет работать или не будет работать
@@seriktulepov8922 токи через транзисторы будут не равны настолько, насколько они отличаются др от друга по Н 21 э в режиме большого сигнала. и всё.
@@alexgonchar3907 а что можно сделать чтоб по напряжения не просаживалось или же другую схему можете снять видео,ну хотя бы был 15вольт и 10ампер,регулировка по напряжения и тока был,по напряжения от чистого нуля не надо мне,мне самый главный по току был чтоб от чистого нуля до максимума регулировался. Можете снять видео,мне 15 вольт 10ампер вполне хватает,но линейный блок питания хотел сделать,потому что у меня трансформаторов очень много.
Можете посоветовать надежную и простую схему для зарядного устройства авто аккумуляторов 12 В с защитой от переполюсовки, короткого замыкания и регулировкой тока

will there be any problem even if we do not change potentiometer
Bro please watch recent video, use long time, same to same of market power supply
Buenas noches no dicen los materiales ques se deben tener graciass
Whats the porpose of 2 serirs resistor at the output..??
for do not heat your transistor
@@RJEDITALL ok,, then if we use high watt resistor in any transistor ckt then.. heat will decrease..?
The transistors works pararel. The resistors are needed to split the load to half on each
Good video except, can't read volt meter, maybe just put your VOM on the load so we can see what is happening. I subbed just now!
Mini volt meter not working, use volt ampere meter
@@RJEDITALL that's what I said in the comment above ... put Volt Ohm Meter on load. :)

How to learn basic electronics step by step
Online course
Sir is power supply me 24v input kartee hai so output
Output same, less 2v
I guess it wastes the power, in contrast to a switching mode power supply?
Yes. Linear voltage regulators are dissipating the difference between input and output voltage mulitplied by current as heat. So it is not good to work with great voltage difference between input and output combined with large currents.
Hai bro we can use 35 volt laptop charger i dont have transformer
Yes
Can I use 60n60 igbt
No bro,
How can we modify this circuit to get 60 amps.
Add more transistor
Can I use 1/4 watt resistor here?
No
The output voltage drop when load is connected
How is this 50v? The regulator you use only supports 35v. Sending 50 v to it would not work.
You add more transistor with parallel for 50v
add some short protection
Ok
Volt aur amp meter alag alag honi chahiye
Nahi
What is the spec of that transformer?
???
@RJ EDIT ALL i mean when i am buying what should i say to seller for this transformer ? What is the specification ? You write 30v 10a , that's it?
