Adjustable Power Supply From Laptop Charger || How To Make Adjustable Power Supply

How To Make a Variable Power Supply. 1 - 15v & 0-10A Voltage Current Adjustable Power Supply
Modifying a notebook power supply Changing laptop power supply output voltage Increase output voltage from 5v to 19.5v for laptop power supply Change its Output Voltage 4-30v 2.5a 60w ac/dc adjustable power adapter supply, I showed you the construction of a current and voltage regulated power supply Only One Potentiometer is Enough. You can easily use this circuit in constant current and constant voltage applications. If you are going to use the circuit at high current for a long time, do not forget to cool it. thanks for watching

Good sir

[@Tech2Treasure]

Thank you for watching

[@MTElectricalworks]

Sir plz ya bta do k ya supply kitny Amper aur kitny volt ma ha plz

[@Tech2Treasure]

3.3Amp 12v

19.5 volt to 14volt banane k liye kon sa resistan use hoga?

[@Tech2Treasure]

Bro who aapko dekhna hoga k feed back per konsi value ki resistor lagi hai, phir decide hoga

[@Naveed_90]

@@Tech2Treasure ok bro. koi r11 aur koi r 13 resistnce chnge krne ka bol rha ha its confusing...

[@Tech2Treasure]

@Naveed_90 bro output positive k Saath bareek print peechhay aa raha hota hai chooper ki taraf usko trace karo or resistor ki value kilo ohams main hogi, jitnay k ki resistor ho us k parrallel main utnay hi kilo ki resistor laga kar dekho output kia aata hai, agar output chang ho gaya to wahi resistor hai jisko change karna hai

[@luckypatle2363]

Hello bro isme 25 v ka capacitor bhi lagana hoga kya

[@Tech2Treasure]

bhai aap nay jo Maximum voltage output lena hai us se 5v above ka capacitor laga dena

[@muhammadyaseen8633]

Aslamoalaikum sir me ne bhi regulater bnaea hy per us mein tl431 do teen dafa ki adjustmint ke baad kharab ho jata hy

[@Tech2Treasure]

capacitor change kia aap nay?

[@muhammadyaseen8633]

Plzz sir help kerai ke aesa kea karoo ke tl431 khrab na ho

[@Tech2Treasure]

aap tl431 k elawa wali koi Supply use kar lo

[@grandgame8148]

Vhi meri pas 19v ka adapter hy main usko 12 volt kase converter karon

[@Tech2Treasure]

Bro same method se but resistor fix lagani hogi

[@Naveed_90]

​@@Tech2Treasurekon c resistnc name ?

[@Tech2Treasure]

Quarter watt fixed resistor ( 1/4 watt) Pelay app feedback per resistor ki value dekho, uskay hisaab se variable resistor se desired voltage set karo or phir variable resistor ki modified resistance value k hisaab se fixed resistor laga do,

[@pakistanaseelfighterclub5122]

Dost meri pas 18.5 ka ho adapter hy main usko 12 volt main kese convert karon

[@Tech2Treasure]

Ho jaye ga but bro uski pictures meray telegram Channel per send karo main kit daikh kar batanay ki koshish karonga,

[@MTElectricalworks]

Ya knsi company ka ha supply

[@sayem4494]

my laptop adapter or any other printer/lcd monitor power supply just trun of when i connect with 775 Motor, any Solution bro? i don’t need adjustable supply

[@Tech2Treasure]

bro check 1 to 10 ohm safety resistor+fuse if used in supply

[@Nazmulsaidi]

you need to give supply to 775 motor slowly. Use a variable resistor in series. start the motor slowly, then it will not turn off.

[@Tech2Treasure]

Yes he is saying right, motor need more current while starting from zero and many supplies have built in protection circuit for overload, when u connect motor directly to supply the circuit sense it as short circuit and cut off the supply, search on internet about your supply and ic's number and figure it out which ic is responsible for overloading cut off, then make some modification in it, you will find schematic diagram of the ic for overload

[@MTElectricalworks]

Sir g ya knsi company ki ha

[@Tech2Treasure]

Toshiba

[@MTElectricalworks]

Is supply ka name kis ha sir g

Sorry, but un can enable English translation in KZbin web player

[@Wishme85]

I have modified my charger, but voltages are not regulating. Please let me know If you have any whatsapp number , so i'll send you the pics of project.
