The transistor ? - You used in the above video was a TTC2500 VCE = 230V 15A
Can i use that as a short killer...?
lovely
Sorry, I have gotten all the other electrical components for this project, but, it remaining the TTC5200 transistor which I couldn't get. Please, what other transistor can I get in replacement of the TTC5200 transistor and still get the same outcome?
Thanks for your reply.
Parabéns.
Esse é confiável.
muitas felicidades.
Hello, Can this circuit charge some capacitors? for example 200v per 1000 uF?
Nice video, well done, thanks for sharing :)
Welcome 🌎
Parece bom, vou montar!!
Рисуй всегда электрическую принципиальную схему чтобы понимать все важные узлы
OK I will try.
Вони цього зачасту не роблять.
Bạn làm con biến chỉnh vặn thuận chiều luôn chứ sao bạn làm toàn vặn ngược chiều Kim Đồng hồ vậy bạn ơi , lỡ làm thì làm cho nó đúng luôn đi
Parabéns!!! Ótima explicação!!!!
welcome
Rất tuyệt vời mạch điều chỉnh điện áp
cảm ơn người anh em.
Great, to remember how I taught students what voltage is and what amperes of current is 😊.
So true!
TRANKS YOU SOU MUCH🇧🇷🇧🇷👏👏👍👍
Welcome bro
MANO VOU REPLICAR PRA CONTROLAR O MOTOR DE IMPRESORA E O MICROONDAS E GERAR SENOIDE NOS IRF TENHO QUE TER 15V AC NOS G DE CADA IRF 👏👏👏👍👍👍👍🇧🇷🇧🇷
It would be really helpful IF you provided a schematic. Why did you not think of that?
sorry
разница в напряжении будет превращаться в тепло, допустим 100в 1а превратить в 5в 1а будет 95вт
yes possible
Закон Ломоносова ни кто не оьменял еще.
Parece muito útil, mas tenho dúvidas: o diagrama que aparece no princípio do vídeo é diferente, pois o negativo vai direto à carga, e, se eu ligar em voltímetro/amperímetro, como serão as ligações? Uma dica: se possível, coloque os potenciômetros trabalhando para o mesmo sentido. Saudações do Brasil.
welcome bro
This is really very good Thanks you so much sir
Most welcome
Hello, very interesting. How to make the voltage change more progressive ? Does it reduce the current or it is a current limiter ? Thanks.
It is depend transistor. 2SC5200 maximum 200V, 15A
Tem proteção contra curto circuito na saída?
Very nice and interesting. Thanks very much. This could b more easy if u could provide circuit diagram of each video.
ok bro.. welcome
Ola...pode usar qualquer transistor com essa configuração se nao tiver esse do video?
yes you can
Tambien que se podria mejorar usando otro transistor para hacer un darlignton por la corriente de salida
Chỉnh áp kiểu tuyến tính nầy khi chạy áp thấp nó nóng transistor kinh khủng. Nếu chạy áp cao thì bình thường, không bằng cách chỉnh duty (độ rộng xung)
Well laid out circuit ! ... but .... like a LOT of these videos , a CIRCUIT DIAGRAM would be a great help for those wishing to construct in a different way ( or modify ) ........ DAVE™🛑
ok I will upload
Can i supply this 100v?
I made this module and it works. But I'm interested in what to do with the potentiometer for voltage regulation because it raises the temperature? Should I install the same 10k but 3 W.? Otherwise, it works well at voltages up to 50 V and the temperature is within normal limits, but at higher voltages it heats up.
It all depend on what you are going to use this circuit for, if it for any kind of lab power-supply then forget this construction, there is nothing in it that is stable in any way, it is a extreme crude way to regulate voltage and current without any feedback or stabilization. Nothing will stay the same if the input voltage change.
It is just a demo circuit to show how to use a transistor as a regulator. It has it's usage, bench power supply is not one of them.
@@K2teknik. ok dear but you should make a video with feedback section and stabilization 😊😊
Very Good for you. Thanks You and Have a Good Nice Day My Friend ❤❤❤
Have a nice day

yes but not have an auto cutoff part.
@@homemade_101 मतलब सर
Can we get constant current output, if load increase also need 100mA constant current
🤔
Why not build a circuit board from cardboard and copper wire flattened out? The copper wire could be drilled as well as connected firmly to the cardboard.
because this is an Experiment.
How many watts is your soldering iron?
35W
Won’t the hot glue melt when the heatsink gets hot from the transistor?
yes hot
Thank you so much

Muy buen video mi pregunta es con una fuente atx de pc 500w podria con el elevador cargar baterias de coche a 14v o tendria que poner al gun diodo y para baterias 3s 18650litio también valdria? Gracias un saludo Valencia (España
3s 18650 OK. But not have auto cutoff.
Como podriA hacer el corte automatico
El bms no cortaria
can we make without the 5w resistor in the output?
How do you set the current to a known value?
🤔
That's a good question.
The circuit is a starting point for future development, you need to draw the schematic on paper or into a circuit simulator and add/modify to your needs.
Some knowledge about Ohm's law will come in very handy.
The circuit as is do not regulate the output current with any kind of feedback, it only regulate the base current to the power transistor and you can't really calculate/predict the current because other factors like hfe of the power transistor is not a fixed value it depend on collector current and temperature, so to set a known value and keep it stable you will need a feedback loop, an op-amp will come in nicely here.
@@K2teknik.Dear you must make a video same project with feedback and stabilization 😊😊
Wow 💯👌 really super vedio ...thanks for sharing this 😎🙏
Welcome
Sir namaste
Supply battery charger me use kar sakte hai plz reply
is the 5w 0.22ohm resistor minus the current?
If you try and supply a load with 15A from this supply the 0.22 ohm 5 watt resistor you have in series with the output will be destroyed very quickly!
👍👍
Can i use 6 Amp diode instant of 5 amp?
Can I change Transistor to control 300V-15A?
max voltage is 230v
Buenas. Tengo que decir que el control de corriente esta mal conectado UNO de sus terminales. La resistencia de 10 ohm, no debe ir a negativo . Debe ir a la salida luego de la resistencia de .22 ohm 5W y tal vez no necesites el diodo para lograr una menor corriente minima de salida
Amazing circuit : few Elements connected without board ..and variable voltage , ampere..nice work..thanx100🌹
Thanks and welcome
Hi bro ,kannst du auch eine effektive batterie ladengerät fur Auto batterie 🔋?
yes, but this circuit is not recommend.
How 2 maximum input voltage supply sir ?😮
100V DC
how much current did the input voltage?
maximum current and voltage 100V, 8A
ok, thanks
That heatsink is severely undersized.
I like your video❤❤
thank you bro..
How could i make this handle 20 amps and 1200 watts. Can i use multiple transiters to do this? and use a 20amp diode instead? Your video says it will only do 15amps and the manufacture specs on the transistor says 150watts. Thank you for any help.
yes it is depend transistors
Keren lurrrrr
सर जी ये उल्टा घूमने पर वोल्टेज बड़ता है क्या सीधा नहीं हो सकता है
При 100V транзистор может пропускать только 0,3A
At 100V the transistor can only pass 0.3A.
Added short circuit protection is better....
yes
Agr input 12 V , 2 A ho to output kya hoga ?
max out 12V, 2A
Sarannya dong,..Bagaimana untuk mendapatkan lebih dari 20amper??
10A
I think that switch mode is better.
🤔
Die beiden POTIS brennen immer wieder durch. Wieviel Watt müssen de denn haben ?
Which circuit should we use to adjust 12v.6 volt 10a:

А что лампу через амперметр то не подключил? И одновременно с вольтметром. Никакой регулировки тока нет, только напряжение регулируется.
no
правильно, друг мой.Я сделал этот модуль и проверил, что он регулирует силу тока за счет падения напряжения.
Very good sir to Good
Welcome bro ✨️
Nice
Congratulations but Where's the electric scheme,tank you
You must add voltmeter and ammeter
yes
Berapa amper maksimum input dan outputnya
Hasilnya ko min bukan plus
it’s going to get extremely warm and you used hot glue to attach the potentiometers, your better choice would’ve been an epoxy
yes this is an experiment. you can apply any other metered.
I seem like ur 47ohm resistor is getting burn
no no it is mistake. it is not burn.
What is max DC input voltage, like 30v 60v 90v 120v???
60V ok
Please, what is the minimum and maximum output of this circuit both the voltage and the ampere? 🙏
20v , 5A

Hello...
Can it be used continuously as 90V 20A INPUT - 60V 14A OUTPUT?
yes 60V
are you sure about this?
Can it be used continuously as
90V 20A INPUT
60V 14A OUTPUT?@@homemade_101
If the circuit is not yours and you have not tested it
Can you send me the original link of the video?@@homemade_101
@@homemade_101NO!!Максимальная рассеиваемая мощность 100вт.(90-60)•14= 420вт!
So what you have is a supply of maximum 90V 20A, and you want to set the circuit to archive 60V 14A at the output ?
That gives you 30V of voltage drop over the power transistor and this at 14A, that result in about 420 Watt displace in the power transistor, 150 Watt is the maximum power the power transistor can handle, so this circuit, as is, can not be used in these conditions.
Be attentive regarding the answer you got reading "yes 60V", it do NOT take your request regarding 14A into account, otherwise the answer is right.
This circuit is just a demonstration of a serial regulation with voltage and ampere adjustment where a power transistor with some, at face value, impressive parameters is used, if you feed it with the maximum input of the suggested 200 Volt and 15 Ampere you got a potential person killer and source for fire, so be careful it is not a harmless toy.
Can this project be used to charge 12v car battery?
yes
Will voltage remain constant when changing current.
🤔
Hi
I make this ... with power supply 12v , 14A , input = output maximum power is 3Amps no more,why???
Transistor = Lost 😊
47ohm = smoke
Three times by three voltage... every time transistor Lost...
47 ohm pins don't connect on other pins.
@@homemade_101
I made it exactly like your tutorial And I connected one 47Ohm (2W) resistance leg to the collector and another one to the potentiometer legs like you... At a voltage of 12v, with a 35watt car lamp, the transistor, resistor, and heatsink will heat up very quickly, and the transistor will burn (about 3Amps).
In Iran, these parts are very expensive and rare, because we are embargoed, and 3 transistors have burned out so far and the work has not been done, please guide & help me, thank you bro 🌺🙏
@@homemade_101 Sir, I have no knowledge or expertise in electronics, I am just interested... My field is web design and programming. So forgive me for bothering you with my questions🌺
Sorry to break it to you, but do not even dream about using this circuit near its claimed limits (200 volt and/or 20 Ampere), it will self-destruct as you had observed yourself.
The circuit is ok as is for what it is, a demonstration of how you use a transistor to regulate voltage and current. In the real world it have not that many practical uses.
I already tried this, fed 60-80v for input then my potentiometer glowing..😁, better u tried this for the worst case..
some time
So how much Ah output is this???
15A
Input minimum Volt and amp ?
30V,5A
Нельзя подключать резистор 2 ватт и потенциометр последовательно. Потенциометр тогда должен быть тоже 2 ватт, а не обычный❗
It is a emitter follower .
Every thing moves with output load & input voltage variations !
ZERO voltage regulation & no current monitoring ( it clamps the base drive voltage ) .
PS
The 47 R & 10 k voltage pot are toasting nicely !
Hi, why don't work potentiometer current volume?I change it, the current remains constant

Warning: This circuit does not work at high loads. The negative line passes through the variable resistor and it has a weak current. There is a big trick. This circuit may appear to work well on the measuring device. Just notice that the lamp lights up strongly when the resistance is raised and does not scale correctly.
Minimum input limit ? How much volt and ampere ?
