- Hello friends this is nice mini power supply adjustable voltage circuit, it is working as well that we can use at home.
Thank you for watching! Please like and subscribe. Comment if you have any ideas for my next video.
Excelente video, yo tenía problemas para conectar el display digital en la fuente y solucioné. Gracias por compartir!
87v
Great!!, what i was looking for and excellently explained for people like me, newbie in the electronics, thanks
Thanks for watching
Magnificent. I have done something similar but with only LM 350K. It can handle just over 3 amps. With a 24 volt transformer the output voltage is 1.2V up to 30 volt DC. Built in 1980 and still holding.
Thanks for watching
with 24V transformer out put up to 30V......Lovely......what a joke..
Why use that 2 resistor???
thank you so much just because of you I learn excellent power supply
Thank you
I really liked how you showed how you did it. Great job, but it does look (FUBR)
pfff lol
Молодец мужик! Все так подробно и грамотно
mis respetos para todos los que nos enseñan su trabajo y de los cuales he aprendido mucho,..pero este se me hizo muy bueno,..excelente
Muy buenas . Muy bien por la presentacion , la musica Ok . y el video way , pero podrias enumerar los materiales utilizados . un saludo . GRACIAS ..
Excelente trabajo, muy explicito y muy práctico, Me permito hacer una observación: En el minuto 7:40 sugiero que el cable amarillo debe ser conectado a la pata Vin del LM317 para poder así obtener lecturas inferiores a los 4VCD el resto: MUY BUENO.
Una pregunta Beto, no sería mas.bien el cable.rojo de alimentación de el voltimetro/amperimetro alimentarlo directamente de la salida positiva del puente de diodos y el cable amarillo en la salida de voltaje ( proveniente del emisor del 2n3055 y las resistencias de 1.5 Ω) para que así pueda medir voltajes menores a el de la alimentación del módulo v/a(4 v) y no se apague dicho modulo al regular un voltaje inferior a los 4volts? Gracias 🙏
@@edgarmendez4398Cual es la función de esas dos resistencias a la salida?

Amigo aqui uso a rede 110v. Este funciona em 110v Ou as peças são diferente? Grato por compartilhar. Parabéns!!
ok, muy buen video, saludos desde Argentina!!!
buenos dias amigo y con una resistencia de 15 ohms tambien se puede hacer
What's the point of the two 1.5 ohm resistors? As you can see the voltage drops from 13.3V to 12V. That is not a regulator, it is a simple emitter follower. In order for this to be a regulator you need a feedback to the output of the LM317.
That's why it doesn't work properly.
when you put higher load, resistor 1.5 will slowly started the load. if does not put it, load will blinking(light bulb)
try to watch channel (sorin- electrical nerd) find cordless video. you will better understand.
Woo! nice idea friends thanks for sharing
thanks you
este si es bueno..pocas palabras y mucha acción :-))
Excellent demonstration and it is helpful to students ,hobbyist and application engineers in the field of electronics !
asi es que se deben de explicar los proyecto lo felicito ya comparto el video excelente
For an 18 Amp transformer, how many transients should I use? can i follow the same steps?
fiz minha fonte ingualsinha a sua fucionnolu perfeitamente, no lugar do potenciomentro coloquei um zerner de 13 volts e no lugar dos trasitores 2n3055 coloquei os bipolares mje 13007 . ta com 13 voltes de saida e uns 20 ampres fuciona muito bem em um som altomotivo
Good idea you explained how to connect one by one
Great word
Great video as always .Keep the good work sir .You are the best teacher .I have learned a lot from you 😁
Thanks for watching
IF THIS IS THE BEST TEACHER YOU HAVE FOUND! YOU HAVE A BIG PROBLEM! .... LEARN FROM PROFESSIONALS, ... FOLLOW AN IDIOT LIKE THIS AND YOU PUT YOURSELF AND OTHERS AT GREAT RISK!
Brow...u r presention is superr...awasemm.....keep it up
Good video, I chose it among all to do my voltage regulator. Greetings from Colombia
I am beginner electronics, no education your video is help me alot
Muy bien, excelente trabajo
Thanks for watching
What do you think if they only use an LM338 that is 5 amps ?, so only the LM317 is replaced and it goes straight out without the need for the 2N3055 ... I appreciate your opinions, regards!
Muy buen trabajo , limpio y practico. Lo voy a copiar, pero con un toroidal. Gracias!
HOLA, MUY BUENO. GRACIAS desde Argentina
Very good sir love you so much,😍😍😍

Pregunta el capacitor pequeño cuantos mf y voltage es se puede usar una fuente conmutada de 19 voltios y 3 amperes
can i use 12-0-12 transformer with 5 amps for the same circuit ?
Yeah like it too ja go the way he draws the wires makes it easy for me to understand and see the connection, Great stuff thank you E 😎
GOOD GOOD AND NICE WORK THANKS
Your channel is awesome! And of course You have received the registration button from me
Gostei de suas explicações e já me escrevi

Really good explanation thank you. Vary valuable. 👏🏼
amigo y para que sirve esa resistencia de salida amigo
Soy un aficionado, en este tutorial sigo todas las instrucciones y cuando lo conecto a la alimentación el voltimetro me queda en 40v,, y me quema el potenciomero, ayuda por favor que hago???
What are the components and cable size for the adjustable voltage transformer and is it for 110v or 220v? I'm new at this but I would like to learn, never too late.
An excellent video, and very useful! Thank you, sir!
thank you for your video.
Use 5v regulated auxillary supply for display(7805)....then display work perfectly....dont connect yellow and red wire together.
Très bonne vidéo et surtout la manipulation avec Paint qui explique bien. Well very! intereting Thank's
Excellent. Your method of explanation is wonderful and revolutionary in the world of electronic. It can be followed every one. So that a beginner like me can understand very well. Thank you.
may I suggest, connecting the 270Ω resistor to the output end of the parallelled 1.5Ω resistor instead of the output of the LM317? That would compensate for the voltage drop in the emitter follower resistors, keeping the output stable from no-load, to full load. (leave the capacitor connected as is, for stability) The LM317 works by making sure the reference voltage between the adj and output remains exactly the same. If voltage drop appears across the 2N5532 and the resistors connected to the emitter, it will automatically compensate. That makes it a true regulated supply. You should not see any change on the volt meter, when connecting a light bulb or motor. Connecting a couple of diodes in series with a low resistance between the output of the large resistors and the BASE of the 2N3055 will limit the current that the transistor can conduct, in case of a short circuit. Make the value low enough, that the current limit built into the LM317 can protect itself, as well as the power transistor.
Your logic is absolutely correct but not seen this change in any circuit related to LM 317 & Power transistor in respect of any Power supply circuit I came across.
C'est parfait . De plus, je ne trouvais pas la solution pour brancher ces foutus Voltmètres/Ampèremètres chinois ... se repiquer sur la masse DC du pont de diodes.... je n'y avais pas pensé.. Il faut dire que le net est truffé de montage à la con.... surtout quand la source d'alimentation est unique... Merci!
thanks for watching
+Electronic Life Hacks thank you .but very important to know the valuo of every electronic set
270 ohm resistör warmed burned
What if i want it to be more than 30v lest'e say i want it up to 60v pls help . And write all components
Excelente. fuente muy buena. Una pregunta maestro cómo conecto la resistencia shunt que vino con mi multimetro, es igual al del video. Gracias desde Veracruz México.👍👍👍👍👍
Short circuit protection required : eventually the USER will accidentallly create a short . . . then what ?
Use a mosfet latch circuit
... the two 10W resistors... cheapest form of a short circuit protection! :)
it just limit the maximum current under to the CE maximum current...
not the most power-wise one, but parts-wise one, is ok! :D
You can add some transistor in parallel to make the output to 3A!
Can you use the input current of 20 volts 5 A in place of 12 volts
Good work, I've 24-0-24 5A transformer lying around, kindly drop me the components list or should I use the same in the video.??
yes
Yes, but use LM338 instead of LM317 or it will burn out.
GOOD WORK AND BEAUTIFUL!Can you do how to make 90v 20amb VDC speed controller for me. From,. GEORGE TECXT , COCHIN
Thanks for watching, I will try to go it
No , 90V isnt gonna cut it , by the way this is not a Transistor this is IC , Transistor is not doing anything its making it worse , it had Current limiting now it has no safety . For 90 V speed controller you will need another IC , Switch probably HVoltage one , and 3 Phase DC motor controller , you are probably talking about that, no this is not gonna cut it , aint no simple way of doing that .
you could use lt783 instead of lm317!! it operates between 1.5V to 115V, which should fulfill your needs!! On the other hand, if you have to add some high power transistors in order for such high current!! there are some clips demonstrating how to connect those components!! I have found some related links below!! See if you are interested in!!

Nice video sir, make this with 12-0-12 2amp transformer to run 24v 1.25 amp dc fan.
Please give suggestions for any further changes.
Deveria ter colocado o esquema eletrico com os valores dos componentes.
*sir* if I use the 5 amp Transformer what should I do,, *reply please*
I was impressed what you shown how you connected the components , can you please show two light automatic indicator,(Green and Red) and name's of each materials, I am not electronic profession but i want to make my own battery charger with your presentation also don't use board diagram i don't know how to use it, Thanks.
This is voltage regulator IC , not a transistor, its Called Pass transistor used for incising current, not controlling voltage, you dont need this transistor for voltage regulation . Lm317 will cut it , up to max 40V , that is about 25V Transformer .
thank you
@@electroniclifehacks2405 No , thank you , amazing video , bit of problem with English and labels, but video is very good and shows beginners what to do . ITs very good
HI

Hello
Your totos are well presented and nice.
But having made feeds with thypons (printed circuits) for high schools with high school teachers (between 1998 and 2011) I would have a suggestion on security: the food should be secure, either in a wooden box as you show not PVC but closed, to avoid electric shock.

Which parts works to control output ampere ?
Is there a way to connect a Potentiometer for amp adjustments? and add 1 more power transistor as well? thank you btw you articulate the steps wonderfully thank u:)
Isme amp. Adj. Krne ke liye konsa pote kaha lgana hoga manual setting ke liye plz reply fast thnk u
good video and helpful.
nice tutorial, sir load dene per voltage drop kiu ho raha hai? ager 18v per load de ker stable 18v chahiye to kya karna hoga is project per?
you will be a successful youtuber not immediately but definitely
Thanks ou
I want to ask if you can use more than 1.5 ohms resistor, or what is the maximum use of ohms on ceramic resistors ... please explain ... thank you ...
great product thanks
can you please make same product 220v ac to 450v dc
Can give all components in written form which use in this video
My PSU cant adjust to 30volt..i use PSU switching 12v 5a..? R2,2ohm 10watt..lm317..r270 ..elco 50v/10uf..?
Very good .nice explain.
Thanks for watching
Irmão por gentileza Manda o esquema dessa fonte por favor
Boa idéia vou fazer aqui também.
Y el diodo o resistencia que lleva el led
the connection scheme was missing
Where to connect wires for output ?
Muy buen trabajo, si le conecto un cautin para regular la tension se caera esta.
hey, how are you with arduino/esp stuff, could the LM317 be controlled by an X9C104 digital pot (100k) or MCP41010 for example
oh i don't know , thanks for watching
no, the LM317 works by Integrating a constant current created by the resistor between Vout and Vadjust. The potentiometer in this video changes the current flowing to the adjust pin. This is outlined on the Datasheet. If your digital potentiometer creates a corresponding current then definitely go ahead and use it,. Or use a cheaper better analog potentiometer for this specific purpose and save your digital out/input pins for something else.
Bro. I got problem of overheating resister while making high voltage with D718 NPN transister ...
How to solve this problem..???
Adding two resistors 1.5 ohm 10W the same video above. thanks
Can I use it for more than 3 amperes, for example 10 amperes?

Amigo donde esta el Link del plano para descargar y hacer esa fuente
Excelente tutorial que ya lo reproduje, mi inquietud es si le puedo poner un transformador de 30 voltios ya que no tengo experiencia en electrónica solo lo hago por pasatiempo que me quedo de la pandemia del virus-19 en la que no se nos permitía salir de casa. Gracias
Pregunta el capacitor pequeño cuantos mf y voltage es
2200 uF a 25Volts ,pero al circuito le puedes meter un máximo de 30V DC ,por lo que tendrías que cambiar el valor de capacitor diodos y resistencia para el led✌
The best ,i like
