Good evening sir, I'm Arup and also fan of your channel. Sir I got a E-Rikshaw Battery charger with Dead Symptom. After check cold test their had PWM CHIP(UTC3842A), SWITCHING MOSFET (12N60), GET CURRENT LIMITING RESISTOR, SOURCE LOAD RESISTOR and RT RESISTOR WAS BLOWNS OUT. From this bad components value I have recovered instead of GET CURRENT LIMITING RESISTOR. After cheking datasheet of PWM CHIP I used the GET CURRENT LIMITING RESISTOR 68 OHM and RT RESISTOR 1K. Where as Other all components was good. After changed all the bad components I had power up by 100watt series lamp. Then problem comming fluctuating. Series lamp also fluctuated. Then I had check all the voltage o/p and opto isolator supply was fluctuated. That's why I had change again opto isolator PC817 and again power up mistakenly direct line. Unfortunately all the bad components again BLOWNS out soon. After all that I had change again all the bad components and this time Power up by the series lamp. Luckily this time problem seen fixed and all the voltage seen good ( O/P, PWM CHIP POWER, OPTO ISOLATOR POWER ). But this time I have seen the somke is come out from some where from the ckt. Due to this reason after power down, I have check again cold test. Then seen Switching FET and it's GET CURRENT LIMITING RESISTOR was over heating. And check also all components primary and secondary site all components was good instead of FET and GET CURRENT LIMITING RESISTOR. After all again power up by series lamp it was seen problem is fixed. But after some time to take a risk I have power up by direct line. But unfortunately this time again also BLOWNS out previous all bad comments. Where as all components over board showing good. One point I have missed to say that here I have used 15N60 MOSFET instead of 12N60. Please help me sir what should I do and what shall be the checking process? To fix the problem. Thank you sir

[@LosMinidriversF1Fan]

It is a quite clear and complete explanation. Im going yo to replace capacitor burned C33 on my PCB, may you handle capacitance and voltage values please?, thanks in advance

[@davidzam1339]

Hello, can you tell me what value is the C33 that carbonized in my source and I don't know what value it is.

[@pdebchoudhury4591]

I wish a tutorial, on SMPS, with substitute different switching ics. How can a MOSFET be used replacing ic if not readily available.

sure i will try to explain all possible ways to overcome this issue

Nice Sharing, i have mean well power supply 320-48 for charging ev 48v lithium battery but supply not give current 6-7 Amps on start it gives 2-3 Amps we replace the other same supply but after some days the same fault occurred, kindly share knowledge about mean well 48v supplies as your detailed style. Best Regards Hadi

[@HaseebElectronics]

Salaam o Alaikum sir i am thankful for your valuable feedback. i tried to search for the circuit diagram for this model, but i couldn't find it. if possible can you please send this power supply to me in my Home address, these days i am in pakistan, so that i can check the root cause and solution, after that i will send back to you as soon as possible. if you can troubleshoot it, best regards Muhammad Ashraf 00962-78-1161084

What's the use of that blue Y1 capacitor that is connected between primary and secondary ?

[@juanchizabaleta2405]

Haseeb,I need,pleased, to know the value of the zener diode ZD2, which is in parallel with C9, (page 12 schematic hct_jsk4210)

[@HaseebElectronics]

i dont have circuit right now. but looking at diagram, i think 18V zener is to be used as ZD2

[@hichamtassi1753]

Thanks for the video, i am having a buzzing oscillating sound in my PSU with a low 4v output instead of 12v. Any idea where to look at ? thank you and salam aleikum

[@HaseebElectronics]

Salaam o alaikum there is some component short in secondary side, OR there is come frequency setting component in spms controller section is fail, so might be its switching frequency is inaccurate

Nobody explains like you do sir. The subtitles running below are causing improper viewing. What's the point if the subtitles are in the same language you're speaking?
