- in this video number {1002D} MW S-150-15 SMPS providing Less output voltage, Mean Well S-150-15 SMPS providing low output voltage, i repaired this 15 volt 10 ampere power supply, it was proving low output voltage (9 volt) instead of 15 volt. and the output cannot be adjusted by potentiometer. i replaced TL494CN ic, it is same as KA7500

Fantastic!!how easily you find the fault!!experience is the best teacher.thank you very much from Spain!
Thanks for this vedio. This multimer is Good i want to buy one
Emeğinize sağlık efendim. Sizden çok öğreceğimiz bilgi var. Ömür boyu başarılar dilerim.
😢السلام عليكم ورحمة الله وبركاته استاذي الفاضل على معلوماتك القيمة وجعله في ميزان حسناتكم استاذنا ❤❤❤❤❤❤❤❤🎉🎉🎉🎉
Simply nice!!! My humble thanks
This is unusual. TL494 needs 7V-40V. 3.9V is too low so I was thinking the fault was with the VCC input voltage, something like burned or open resistor. But as usual your diagnosis is correct and you fixed it :-)
Weldon keep sharing
Nice teaching sir thanks👌👍
best regards

Mr Haseeb thank you for your nice video 's
good evening and I never knew that it would be so easy to repair the board
Very good and useful information sir thanks
Super 👍 sir thank you
best regards
Deep ❤knowledge ❤share pranam❤
salaam bhai jaan. khush raho
Am also waiting to Tamil....
Informative vedeo. Thank you so much.
❤hesseb brother
😊you are always good
Thanks for your informative video. Can you help me troubleshoot smps dual output. 5Vdc ia good but no output in 24Vdc.
Sir this video is really different for me compare to other videos. Because your showing the ic pin detail to us, like this video here after please keep showing us. really this make sense to me. And one more doubt sir i check the data sheet, Vcc supply it should be 7-40v. But inthis smps only we received 3.7v. Is this acceptable supply voltage? Thank you sir.
Thank you very much
Love you brother ❤
Thanks for its shared
Sir apsay ek requ st hai please..kindly bu k converter design kardijeyey 72 to 12 volts ka . Design ,calculation and simulation k sath. Zindagi ka eshan hoga meray per.
👌👌👌👍👍🌹🌹
Mr Haseeb
thank you for your nice video ,s
can you make this smps works on dc 48v input to 12v output thanks again
👍
wow amazing
Sir. Your video list the computer UPS repairing video is have? Please inform me. I likes all your videos. From Tamilnadu.❤
wow it is really great coincidence, i am planning to make UPS repair video in these days
it will be available very soon
Thanking You...
Vanga thala vanga😜🎉
Could have shown the ref voltage on new IC.
Nice! Please load test after repair? Components don't blow up on their own under no load. Why did the IC go bad? Do other failing components cause the IC to burn up under load?
Voltage is good but useless without current capacity
If the control lamp connected in series with the 230V AC power supply stays on continuously, does it mean that the respective source has problems on the DC voltage output side? Thanks for the explanation.
It shows that there's a short somewhere on input ac side.
Hello... the problem I have is not finding the problem and the power source (12 volts 30 amps)... instead of being 12 volts, the output is about 5 volts and the voltage changes very little by turning the potentiometer... I replaced two filter capacitors due to the loss of capacity (I tested the parts with a multimeter and a T7 tester) and the voltage of each of them is about 150 volts and the total is about 300... I also tested the MOSFETs with a tester and a multimeter and they are fine... I also replaced all the electrolytic capacitors around the switching IC... I also tested the transistors and all the diodes around the switching IC... one interesting thing is that the ground and VCC voltage I get is about 7 volts There is, and I think this voltage is weak!... But the REF voltage is about 5 volts... I have to say that I even changed the IC for testing and there was no change!... In short, I wonder where the problem could be.
In these symptoms
It seems, there is problem in smps controller ic
Hocam bundan sonraki videolarda entegreyi sokmeden diyot modunda kontrol edermisin sonucu merak ediyorum ne aralıkta değerler verecek
Is the noise thats coming from the power supply when u applied 220 normal ?
Sir please SMPS me capacitor vcc voltage nahin aata hai kya kare sir please Hindi me boliyee dhanyawad
bhai aap ne SMPS mein lagi IC ka number nahi btaaya. aap please IC ka number btaa do. to easy ho ga
SDC606 ic equivalent ic
Selamün aleyküm kardeşim. Bu entegreyi hemen tahmin ettin. Bunu nasıl yaptın. Ayrıca başka bir neden varsa ve yeni entegre yeniden bozulursa? Entegreyi düzeltince sorunun devam etmeyeceğinden nasıl emin oluyorsun?
plz i did and tested the 12 pin give me 9.30v and Vref give me 5 volt but my main output is 4.5 to 5.60 and should be 12 Vdc tested the daiods and the caps and resestors nothing at all i just hearing nosie come out of the transformer the big one what i need to check thanks
Plz engineer answer this one I av one with the same same problem and no matter how many videos I have watched none has such kind of fault.some noise coming from the big pulse transformer hence low output.Thanks.
