- DC voltage and current adjustable power supply, DIY dc voltage controller.
This is a dc voltage controller simple DIY using a 2sc5200 transistor. This is a basic voltage and current adjustable power supply. But not a powerful dc voltage controller. You can supply an input maximum of 200V, 15A.
Components used in this project:-
1. 2SC5200
2. 47 Ohm 2W
3. 0.22 Ohm 5W Resistor
4. 10k Potentiometer
5. 10 Ohm 2W
6. 5A Diode

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.
Very Good for you. Thanks You and Have a Good Nice Day My Friend ❤❤❤
Have a nice day
Brilliant project congratulations
It would be really helpful IF you provided a schematic. Why did you not think of that?
sorry
Esquema para hacer algo tan elemental ?

no bro
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?
For how long this circuit can support an instrument running continuously with 5 amps ?

Can you be a regulator on a motorbike? , plus input diode
Very clear welding❤❤❤
I like your video❤❤
thank you bro..
Sarannya dong,..Bagaimana untuk mendapatkan lebih dari 20amper??
10A
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
How can change connection for clockwise
Its working Anty Clock wise for voltage and current increase
I made the same circuit and it worked great at first but when i connect bike's 35 watt headlight lamb which uses 2-2.5 amps, My both amp and volt regulator 10k potentiometers burnt. What's the solution????? (The only difference i had in my circuit from yours is i used 39 ohm resistor instead of 47ohm cause i couldn't find the 47ohm one)
I want max 300 volt and 30 ampere controller for my solar 2 string in parallel. what can i do for circuit 🤔
可以用这个炸电容🤭
Can i use 6 Amp diode instant of 5 amp?
yes

can we make without the 5w resistor in the output?
This is really very good Thanks you so much sir
Most welcome

Hi, why don't work potentiometer current volume?I change it, the current remains constant
try this is : th-cam.com/video/9vWsRIokOIk/w-d-xo.htmlsi=Q04ZFxMZgk4m7T-j
@@homemade_101 don't work this too
It's best
Can we get constant current output, if load increase also need 100mA constant current
🤔
We use any of ampere mosfet its a choice or not please answer my question i made it ?
There is no mosfet
Nice video, well done, thanks for sharing :)
Welcome 🌎
I have a question, with your homemade DIY DC voltage controller. My power supply is lithium battery cells 4S4P 40A (my BMS is for a 4S 40A). With your homemade DC voltage controller can i have a constant voltage to 12V (and 20A is enough) whereas my battery cells will decrease little by little its voltage ?
you need zener and capasitor for it
I like this method better than diagrams . For me is easier to understand. Thank you sir!
Welcome
is the 5w 0.22ohm resistor minus the current?
Hello my friend.
If i use 500v mosfet example irfp460n it could be possible 300v input of my solar panels to charge 16s lipofe4 batteries
about 56v output!
I want to make something reliable just to make this work
and I can fix it by myself.
Thanks 👍
try
I'd like very mutch to get the schematic of this circuit . . .
Ok i will try other videos
Will voltage remain constant when changing current.

Tambien que se podria mejorar usando otro transistor para hacer un darlignton por la corriente de salida
Parabéns.
Esse é confiável.
muitas felicidades.
Great, to remember how I taught students what voltage is and what amperes of current is 😊.
So true!
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!
Amazing circuit : few Elements connected without board ..and variable voltage , ampere..nice work..thanx100🌹
Thanks and welcome
How many volts input so out put put 12v20amp
Pls reply
Input can be 15A DC, but how much watts those potentiometers can handle? For a medium size project, they need to be 10 watts at least.. Good project, but limited usability.
I made the same circuit and used the same 10k carbon potentiometers.they worked fine while testing 775 dc motors but when i connected 35watt bike headlight lamp, both potentiometers burnt. (My power supply was 24v 5amp transformer)
Hello, Can this circuit charge some capacitors? for example 200v per 1000 uF?
can we use 220v in,,
जबर दस्त सर जी,क्या इसमें वाल्ट और एम्पियर कंबाइंड वाला डिजिटल मित्र लगा सकते है।बाईटरी चार्ज करने के लिए।
yes but not have an auto cutoff part.

What is the input ampere
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? 🙏

Hi bro ,kannst du auch eine effektive batterie ladengerät fur Auto batterie 🔋?
yes, but this circuit is not recommend.
Can this project be used to charge 12v car battery?
yes
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 😊😊
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
Nice video,but have not shown the current in multimeter that it is going up and down
sorry
this is good but 3A. th-cam.com/video/vUOBuOsQ_0g/w-d-xo.htmlsi=Ag1gI8vAgtscbdix

ok, thanks
Can provide 20v ?
yes
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.
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 😊😊
разница в напряжении будет превращаться в тепло, допустим 100в 1а превратить в 5в 1а будет 95вт
yes possible

Can I charge my electric scooter
lithium fero phosphate battery
48 volt 24 ah
no. this is experiment only.
Can I change Transistor to control 300V-15A?
max voltage is 230v
Minimum input limit ? How much volt and ampere ?
30V 5A
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
can for batry charge brother ?
yes. but not auto cut off protection
wokey bro
Rất tuyệt vời mạch điều chỉnh điện áp
cảm ơn người anh em.
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

I use this to charge Li-Ion Battery?
yes but set 4.2V and not auto cutoff
What is the ampere....

Where you got 100 volt supply ❤❤❤
That heatsink is severely undersized.
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
то что искал! спасибо
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.
So how much Ah output is this???
15A
Very good sir to Good
Welcome bro ✨️
How 2 maximum input voltage supply sir ?😮
100V DC
Smoke Machine! 100Vin, 1V 20A out = 1980 watts burning the transistor (150W package) on a 5W heatsink, pure rubbish claims.
