Great video as usual many thanks. You use parts from scrap power supplies. At which point do you decide a supply is scrap? I ask as you seem to fix most things.

[@HaseebElectronics]

when the repair cost exeeds than the 65% of the actual cost. then i recommend to not to repair

Thank you sir. I have one question where is the optocoupler in this power supply ( or in another way , how they isolated the secondary portion fro the primary portion). again thanks a lot sir for all your help

[@franciscomaciel4963]

Fitst thank you for sharing your knowledge. I really appreciate it 🙏🏼 Question: I live in Mexico (127VAC) and SMPS was switched to 220V (insted of 110V) so it get damaged during working for some time. Now is making a buzzing sound and switching on and off. Is this a similar damage?

[@scroopynooperz9051]

Yo my main man Has! Has tell me, have you ever tinkered in upgrading 110v powertool chargers to 220v? I'm getting so tired of carrying around extra step down transformers because the cordless drills (for some weird reason) are always way cheaper in 110v! I have saved up for some Makita and Metabo HPT tools for jobsite BUT carrying around extra transformers is always a pain.

Hello, Can you explain please why an smps that uses ml4800 IC, the vcc and reference voltages are low, instead of 13V on vcc it is 7v. The reference voltage also low instead of 5v.

[@skecmrepairandcars2590]

Mashaallah sir nice explanation

[@maissathiaw963]

sir haseeb how are you i have power supply smps of satttelite receiver have 5 volt output without insering the cable in the motherboard port .Now when i connect the cable conductor in the same motherboard port power on the 5 volts is going to up down 4 volt 3.2 volt 2.58 volt etc please can you help to troubleshoot thanks

Peace be upon you. I have the same power supply, but it makes a buzzing sound and the output voltage is 16. There is no control over the variable resistor, and when loaded, the voltage drops. What is the reason?

My exact same smps provide voltage 12v output when connected with series lamp...when connected directly to supply, input fuse gets blown immediately...input voltage selection switch us set at 220v.

Isn't it dangerous not to discharge the condenser, sir?

[@MarshaJ8800TU]

Many power supplies have in circuit discharge resistors; but just in case, he always checks the voltage anyway... at 2:30 in the video.

10:55 Sir, please don't teach us to regulate the output voltage WITHOUT any load. As you know, a lot of power supplies output higher voltage on idle, and then it drops to correct value when you apply the load.
