DC Voltage and current Adjustable Power supply, DIY DC voltage controller 

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.

yes possible

welcome bro

sorry

Esquema para hacer algo tan elemental ?

@@homemade_101 ... No se disculpe, el que quiera el diagrama... Que lo Haga !!

no bro

Ok i will try other videos

Zaten 24 to 12, 80amp düşürücü 250€ böyle kolay olsaydı😂

Lmao 1980 watts, meanwhile the maximum power dissipation is 150 watts. 😂

because this is an Experiment.

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 👏👏👏👍👍👍👍🇧🇷🇧🇷

muitas felicidades.

cảm ơn người anh em.

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 😊😊

Welcome

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.

30V 5A

Super sir iam ur fan How to connect digital volt meter and fan...Thank u

Welcome bro..😇

3s 18650 OK. But not have auto cutoff.

Como podriA hacer el corte automatico

El bms no cortaria

yes

this is better : 4A ok. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1tJxmAp36Cg.html

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.

thank you

welcome

enjoy

There are a bunch of videos on the web of similar circuits.Several are described as voltage regulators. None of them are. They are, as you say, emitter followers or source followers. They can still be useful, emulating a rheostat, after a fashion (with a circuit a lot less tolerant of transient overload than a rheostat).

@@d614gakadoug9 I think that many peoples notion of what they see is wrong, they read "Adjustable Power supply" as "This is the same at the Adjustable Power supply I buy from a shop where I just set the voltage and current and all just works", this is a wrong assumption, it is no a stabilized adjustable power supply with builtin protection, it is just a simple demo on how to regulate voltage and/or current with a transistor. I understand that people get exited "200 Volt" and "15 Ampere", these parameters it is just sort of guesswork based on the datasheet of the transistor, you will never get all maximum parameters at the same time, it is whatever you hit first that is the showstopper, most people do not understand this.

Thank you

yes hot

Same hoga mgr adjustable hoga volt with amps

OK I will try.

Вони цього зачасту не роблять.

yes

sorrry

can't bro sorry

ok I will upload

Can i supply this 100v?

For how long this circuit can support an instrument running continuously with 5 amps ?

@@homemade_101 Thank you for the video and keep on posting some more updates, we are learning.

no

правильно, друг мой.Я сделал этот модуль и проверил, что он регулирует силу тока за счет падения напряжения.

no no it is mistake. it is not burn.

Welcome 🌎

sorry

yes this is an experiment. you can apply any other metered.

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 😊😊

Thanks for your comment and saving my time

It is easy to make the schematic from the video, pause the video at around 4:31, change to a high video resolution and knock your self out with pen and paper. If you cant do this, then your knowledge about electronic is that poor that you do not need the schematic in the first place.

@@K2teknik. YOU REA SUCH A WISE MAN AND YOUR ELECTRONICS KNOWLDGE SEEMS TO SO GREAT IN GIVING ADVICES. PLEASE DON'T SPILL YOUR IDIOTIC ADVICE

Emitter follower & a voltage divider on the base 🤦‍♂

sorry bro

100V DC

yes you can

Have a nice day

some time

yes it is depend transistors

🤔

ok bro.. welcome

no. this is experiment only.

10A

i will try

maximum current and voltage 100V, 8A

ok, thanks

thanks

60V ok
