Well done! Master! Great job! Everything is clear and precise! Respect! There is even a scheme! When there is a scheme, I will still come here and look. . Молодец! Мастер! Отличная работа! Всё чётко и точно! Респект! Даже схема есть! Когда есть схема, то буду сюда ещё заходить и смотреть.

Tip 3055 максимальный ток колектора 15 ампер,в вашкм ванианте в линейном режиме максимум выдержит 5 и то не долго,перегреется,потрму что сопротивление открытого канала буде велико,не обманывайте людей про заоблачные 20 ампер

Mạch điện lý thú rất tuyệt vời xin cảm ơn đã chia sẻ với khán giả

Your circuit is interesting, I just simulated it in Multisim and it works very well. Of course, it does not support 20 Amps due to the 3055 but it can be replaced with another transistor that does support it or put 2 or 3 transistors in parallel with their respective emitter 0.1 Ohm resistors. thank you. regards.

that was great 🎉❤

esa fuente esta genial para hacer baños electrolíticos oro plata estaño ectr ...... esta super genial .

Very good! Thks, friend!

Excellent ❤❤❤

Mantap 👍

Subscribed and liked it too

Gran video. Qué componente es el de color azul? Será un diac db3? Gracias por su valiosa respuesta.

Very good

Greeting! Very educational videos!!! Well done Professor! What video and build would you recommend for me to make a power supply with DC input and output~ 4-6V and ~8-12A! That it can work without interruption and overheating for a long time! Thank you

It's working bro thanks you.

Good project 👍

Same circuit banaya hay working fine but 3055 bohot juldi heat hojatay hain 5 mint mai jusy on 2 amp load per mene 2 trinsister use kiey hain achi heavy heatsink k sath koi advice den transister heat bohot hota hay

20 amperes com o 2N3055 nunca talvez um MJ 802 com um bom dissipador poderia chegar próximo desses 20 amperes

GOOD PROJECT

Very good friend.

It makes a 0-30v 0-50a source with adjustable voltage and amperage. I didn't find anyone on RU-vid with this source.

😍😍 super.... 😎😎😎😎 good job 🤩

Well it looks like a clean build but reviews say it does not work properly.

Hello and congratulations for the video, I wanted to understand at minute 4.50 the cable connections on the right potentiometer are different from those seen at minute 5.01 the center of the potentiometer goes to Bd139 and not to the diode, so have you changed? thanks and good luck again, I would like to build one too.

👍👍👍

Como faz pra proteger a saída contra curto?

Напиши пожалуйста какие компоненты в нем есть, а именно транзисторы и мосфеты

Good job❤

Kindly I ask you in the sketch not showing digital Amper also on the circuit please advice how to connect

do i really need Lm 317? my supply is only 5V i need to drop it to like 3V. i have other two except lm317

thanx

Why does my input voltage become one third?

If used to regulate the charge of a car battery, will this circuit work or fail???

does if we use long time and max power the mosfet will burn or not? i follow your other video when use high power and long time mosfet seeming smell it mean will burn soon.(I'm also use Heatsink)

Bhai circuit kam nahi kar raha hai maine sare types ke 2N3055 transistor laga kar dekha par work nahi kar raha hai.

Can I use IRF540N in its place

Hey what should I do to make it 20 amp

O problema destes circuitos caseiros ,e disto ninguem fala va-se la saber porque,e a sua queda de tensao,quando se aplica uma carga...uma lampada ou motor na saida de ajuste,ou seja por exemplo uma lampada de 12 volts 21 watts quando ligada na saida de ajuste a 12 volts reais,nao tem o brilho que deveria ter ao ser ligada a 12 volts reais,e se na maioria dos videos de facto mostra a lampada la ligada com os 12 volts e o brilho normal,e porque a voltagem la injectada de momento nao sao os 12 volts reais mas sim uma voltagem superior talvez 15v 20 v ou mais para ela dar o brilho normal,e para provar isso e muito facil em antes de por a carga lampada e regular a saida ajustavel para os 12 volts sem carga e so depois ligar a lampada,entao ai pode-se verificar a queda de tensao de 12 volts reais para 7 volts 6 ou 5 volts,porque de facto nao pode ter uma quebra tao acentuada,no aceitavel talvez 0,5 volts,dai a grande lacunas destes circuitos caseiros,nao quero dizer mal destes projectos e bem haja quem os faz e ate sao interessantes,mas na realidade tem este senao.

at the end, why doest show the voltage only current!! thanks for sharing !

Bhai kaya iss circuit se lithium battery change kar sakte hai

بسیار عالی🎉🎉🎉

How to make 4 volt 6 amp variable power supply for mobile repair work .please make perfact. work mobile short cutter

Why didn't use condansator?

Sir Esme outo cut banakar bhejiye plise

Video shows 3 transistors but diagram shows 4. 7805 is missing in the video. Which one is correct?

Where are the condensators??

Can I give 0 to 60 v 20 ah?

Resistor value 120oms ?

Good

Percobaan untuk pengukuran Amper / arus listrik kurang jelas...maaf..

how to srep down 12 volt 6 amp to 12 volt 1 amp simple mudul or a ziner diod any idia

The blue thing is a resistance? You didnt write what it is, do you hsve the skemTic?

даже лампочка не горит

Really? Does anyone understand how the current is regulated?

Sao nâu đỏ nâu mà lại hiển thị là220 ôm

BD139.....D882--analog???

TIP 3055 ,20A????!!!!

دوست عزیز ، لطفا پاسخ بده و استیکر و شکلک برای ما ارسال نکن ، عنوان ویدئوی شما 0 تا 200 ولت متغیر است ، چطور ممکن است با رگولاتور lm317 بتوان این میزان ولتاژ را کنترل کرد ؟ لطفا پاسخ واضح بدهید ، در غیر این صورت مجبورم گزارش دروغ یا تخلف پیج شما را به یوتیوب ارسال کنم ، تشکر

uéeee mas nao era 10amperes........kkkkkkkkkkkkk

Can this be powered by a twelve watt power supply of twenty amps sir

Do not good working

Keine Schaltung??

TIP3055 and 10 A 🤦

Мозги надо включать а не музыку Хрен там а не 20а в линейном режиме

Грамотную регулировку тока так и не увидел! Транзистор 3055 стоит дорого для такой несерьезной регулировке! на микросхемах дешевле!

I never saw a proper current control! The 3055 transistor is expensive for such a frivolous adjustment! It's cheaper on microchips!

e max 5 amp

Excellent ❤❤❤
