Nice. I used to do the same to check cheap Chinese(aliexpress) power supply current rating. From experience, I tested 24V 20A power supply and I did the same test by using the same as yours, but larger. I calculated R = 24V/20A = 1.2ohm based on nameplate, so I bought 5pieces of100w 6ohm to test this power supply. Honestly, those cheap power supplies were overrated for more money.

[@HaseebElectronics]

Awesome You are right. In these cheap brands, there is no quality control and standards Printed values are far away than the physical values But comparing price and quality. These power supplies are good while operating less than 80% of the rated current

[@chirots]

@@HaseebElectronics You are right. When I want to use 24V 30A, I will just order 2units of 8-10USD 24V20A and parallel. Or I just buy 30-35 USD second hand meanwell 24V 30A. I guess it depends on the work. I would install quality power supply in control cabinet, and cheapo one for occasional use. Your videos are very good and informative, I often come to watch on certain topics that I am not really sure.

[@HaseebElectronics]

@chirots yes if we get secondhand branded power supplies in good condition That is much better than purchasing new low quality power supply Sometimes the polarized capacitors on DC rail.

[@chirots]

@@HaseebElectronics Sometimes, we cannot get the second hand at the reasonable price or at required spec. It is either too small or too large for the work. Usually, you will find the second products that you really need when you have already bought cheap quality products. This just happened to me last week. lol...

You can also make a nice resistor out of pencil lead... I have been experimenting with it recently and it actually nice, but be careful it can glow hot

[@HaseebElectronics]

great the best option is to use heating element of 1000 electric heating wire

sir we are learning lot from you sir thanks for uploading very useful videos sir pleas teach us about bridgeless pfc working principles

I also want that you explain pfc base power supply. Such as PM3398B-6P-1-3P-E. I will be very thankful sir

[@HaiderAli-gr7pb]

[@ramaswamyranganathan9171]

Sir in one of the you tube video uploaded by a blogger in which I saw he is measuring current of SMPS by connecting multimeter set in 10a and com point and then applying parallelely to the SMPS output.

[@HaseebElectronics]

that is not a good method he is using multimeter as a load, while multimeter is not a load. it is a test instrument because in multimeter, there is a fast blow fuse, if we connect to high current source, immidiately it will damage it must be connected in series with any load

[@ramaswamyranganathan9171]

Please upload test load in lower voltages in 100v. Is it giving same current? Sir, since I have brought various SMPS on line and found deviation in current.

Sir i know that this smps can carry 24.64 A but what is the output ampere mension on this smps

[@bantidasAB9475]

Hello haseeb sir please is power supply ko explain kar dijiye ki ic tl 494 kaise work kar raha hai signal transformer kaise work kar rha hai feedback kaise work kar rha hai current sense kaise ho rha hai ye all in all ye power supply ko diagram mein explain kar dijiye

[@palanir273]

Hi, rally it good thanks you so much. please help me how to select topology and what are the critical parameters consider for converter topology selection. E.g 48vdc input, o/p 12v/10A isolation cccv driver for charging application, this we can design flyback or forward or push pull or half bridge. But how to select for topology for start up. Pls help me

[@Micro_Tronix]

Sir, thank you very much. I need your support to find a problem in smps model: aps150rf-d. the o/p 24vdc is good and the fan voltage is 10.5v, when connect the fan socket the fan voltage drops to 3.6v but 24v still good and the indectation Led light goes down. I'm change the o/p capacitors but still the problem the same

[@sunilkarki5738]

dear haseeb sir can you help me by designing a universal load tester with voltage varying from 1 to 440 volts.

[@HaseebElectronics]

brother i don't have practical experience in this field. i will check if i can find some solution, i will contact positively

Asalam alakum sir mere pass ek 6 volt battery Ka smps charger ata ha .us ke output nhi aa rha ha. Koi bhi component short nhi ha. Thori der bad power transistor heat hota ha.halanki transistor bhi thik ha .kia problem ho skta ha.please zaror bataye..

[@HaseebElectronics]

please check its output circuit check start-up resistor for initial starting feedback circuit agr cut na karwaaey to transistor heat up hota he

[@WildAnimal1992]

Sir feedback keliye optocoupler nhi laga hwa ha.startup resistor ki waja se bhi transistor heat hota Kia?

[@HaseebElectronics]

if there is some PF capacitor with transistor, check it or may be transformer

[@nassimkoubeissi5814]

if voltage drops 10% below normal ratings then it's max power can deliver .

[@HaseebElectronics]

no, when the power supply looses it's load regulation that is most of the time 0.5 percent of the nominal voltage that peak point is considered as Pout Maximum at peak voltage and peak current we have to calculate

[@nassimkoubeissi5814]

@@HaseebElectronics when the power supply output loses regulation it means the feed back circuit reached its maximum adjustable point that puts the power switching device on primary side at critical operating point if it's a low quality design it won't last long until it fails (without input DC pfc circuit at primary side, no thermal shutdown circuit , no over current protection shutdown circuit. when output start losing 10% of it's output nominal voltage this point is its maximum safe power to draw.

[@HaseebElectronics]

yes in that scenario it is to be calculated for safe range for an immature design
