A Simple Trick to Get Variable Voltage from Any Fixed Output Power Supply!

Конечно, МОЛОДЕЦ! Но я бы не стал сажать на термоклей переменник к радиатору. Его лучше установить на корпус при помощи кронштейна. Я все это сделал еще 7 лет назад, когда мне попался точно такой же блок питания с бракованным подстроечником

[@DrHarryT]

Keep in mind that no matter what voltage you set, it's maximum output is 15.6W. That 21W automotive lamp will cause the power supply to overheat and it will either thermal shutdown or burn up at that load. It's the switching transistor that would burn and thermal shutdown will only happen if that feature is built-in with a temp sensor on the heatsink. That's a pretty big supply for only 12V/1.3A [15.6W] You can get small wall warts that put out 3A@12V and small laptop like/style power supplies that put out 10A@12V.

[@ZAFERYILDIZ52]

yes the total power is constant but works extremely well at lower values

[@billsmith8853]

@@ZAFERYILDIZ52 If you draw excessive current at a lower voltage even without exceeding the power rating you risk burning out the transformer secondary winding.

hi . good job but it better to instal 2 potentiometers . 2nd is fine ajust

[@ZAFERYILDIZ52]

alternative can be reproduced the important thing is to understand the step up to the potentiometer

[@arunchatterjee1887]

I have already one 12v 10 amps powersupply of this type, I like to convert this variable powersupply like you, what will be the resistance value of those 2 resistor, pl. Confirm

[@sinanyc.2105]

Ustam emeklerine sağlık benim sormak istediğim belki bazı arkadaşlar içinde faydalı olur bu smps adaptörler çok bulunuyor ve tahminim herkese bir tane vardır benim isteğim ustam aynı 12v 5 yada 10 AMP lik bu trafolarda senin yaptığın şekilde aynı direnç ve pot ile yapailirmi yoksa malzemeler değişecek mi birde ustam buna akım (AMP) ayarida yapıp bir vedo daha paylaşırsan dadından yenmez tekrar emeklerine yüreğine sağlık ustam ❤️👍

The little TL431 circuit parts are very good to use in so many ways. I've been using them for decades now...

[@ZAFERYILDIZ52]

Definitely a great integration.

[@lohikarhu734]

have to check output capacitor voltage!! usually only 16V on 12V supply, so change to 35V for *reliable* 16V output...poor quality capacitors may go "poof" if used at maximum voltage for any longer time!

Cok güzel bir uygulama elinize sağlık bu aşamada eksik kalan smps üzerine sabitlenmis voltaj gösterge kiti bu da oldu mu müthiş olur. Başarılar diliyorum yeni videolariniz için takupteyiz.😊

[@ZAFERYILDIZ52]

biraz daha geliştireceğiz saygılar ve teşekkürler kardeşim

[@PF-gi9vv]

You might find some PSU will start switching on and of if the voltage goes too low. This is because the output voltage from the transformer to the pulse width modulation controller chip drops too low, and you get that clicking on an off from the PSU.

[@ZAFERYILDIZ52]

lower values ​​will not be a problem.

[@Habibulla.M]

Nice Idea. Will make one ....

Se este ajuste de corrente poderia se de 0 a 1,2 Amperes, neste caso só consigo se no LM317 estiver na saída do do potenciômetro '0 volts' estiver um lm 317 ltz com 100R como constante, ligado

I have MW LRS 150-12 and there isn't feedback circuit with TL431 but just a series of smd under pcb. Is enough just replace the trimmer with an higher impedance potentiometer for get a range 6-13V?

[@trvenugopalan2800]

Where to buy& the cost. Available on line.

[@kychemclass5850]

If you reduce the voltage, can the internals handle any corresponding increase in current? Similar questions exist if you increase the voltage (beyond the previously fixed voltage) will the components get fried? My serious advise if you want a variable voltage supply BUY ONE, unless you happen to be a very highly skilled/competent in power circuitry and know exactly what you are doing.! I really admire people who play with electronics but there are are always dangers - fires explosions and electrocution which can be fatal! The rusts massively increase with decreasing skill level.

[@Winnie_The_Poorer]

Can make it output 1.5v ?

[@The_Traveling_Clown]

Eu vou fazer algo similar a que você está fazendo no vídeo. A diferença de meu projeto é que eu estou usando um alimentador de computador.

I try to modify a PSU of 12V 12,5A that actually deliver 13,7V in this way to obtain approximately 16V so I can charge with it a 12V 92A AGM battery. On my PSU it have on the PCB 2 resistors of 2,2K. I used a 220R resistor and a B5K but it's ticking, hardly starts for 2-3 seconds and stops, delivering a maximum of 9V... Any advice, what values to use for the desired 16V as output?
