Excellent

[@ErsinFahredin]

wow nice!

[@besthelp4194]

Hi bro. i make this circuit. after test with old ATX transformer it's OK. But after the assembly is completed, there is no voltage at the output. Please guide me in getting the solution

[@ZEESHAN4186]

How to buy this complete circuit

[@Kozuki_oden67]

I tested with ATX transformer with diode and capacitor rectification the voltage out is 1.5v to 2v is small transformer winding is ok??

[@LongTechnical]

Maybe you wrong. Check your transformer and winding

[@rpp139]

Nice Bro, to get 55-0-55 what to be modified?

[@CoDienTuLinh.CaiLayTG]

A cho hỏi để cạo dây đồng nhiều sợi như thế a cạo từng sợi hay có cách nào khác ?

[@muharyaarya5825]

Mantap mas brow???jika ada link penjualan pcb ini tolong disertakan ya mas.

[@ansssaja7721]

Sir, is there a video about how to make and practice making a self-SMPS Self Self Detex Full Bridge that is equipped with over curent protectors, over temperature protect and the delay of Sofstart? and the power of the SMPS until 2000Watt?

[@LongTechnical]

No bro

[@ansssaja7721]

Do you have a video How to Make a Fullbridge Self-Oscillating System SMPS with Over Curent Protector + Over temperature and Sofstar sir?

[@LongTechnical]

No bro

[@imranajmal9422]

This parrot core calculation e r l 35 and 35 + 35 voltage please this video

[@abuhasan4079]

Sir, irf460 MOSFET replace 25n120 igbt can I used?

[@shubhamviahwakarma8930]

Hello sir aapane ek video Banai Thi jismein aapane 1000 wate amplifier banaya tha lekin Uske circuit diagram aur aur control board ke bare mein nahin bataya ha

[@shrikantmande9054]

kindly provide the schematic diagram

[@Kozuki_oden67]

I brought 22mh line filter , it is very small in size can I use it??

[@LongTechnical]

OK bro. No problem

[@theconquerorstv506]

Please show proper way of winding the oscillating trafo, I learnt it has polarity that has been my problem

[@leonardslz4970]

VERY NICE BRO! :))

[@Kozuki_oden67]

I am getting a hum sound in main transformer is it ok

[@LongTechnical]

It's not good bro

[@leonardslz4970]

Please can you make 48V 35A smps source (charger) for a Li-Ion cell high power bank? I really remain grateful if you can do it.

[@quanghoang04]

👍👍

[@jaynikode4595]

Brother please make 1000 watt class d amplifier

[@ajiebae9652]

I have irfp460, it's work?

[@kevincastro156]

can work it 120v?

[@EA-cq2pw]

How to make a multi ouput led driver? From 220v to 5 dc but with many output and each limited to 500 ma?

[@trissmerigold7197]

to limit current is easy, a simple 1.2 ohm resistor in series to the load, when the current exceeds 500mA a voltage drop of more than 0.6V appears on the resistor, with this you can activate a transistor that turns on the optocoupler directly. This is not the most efficient solution (wastes 0.3W at full load) but it is the easiest. to have different voltage output you must change feedback. what is the voltage range that you want?

[@huuphamt8226]

Có bán pcb ko a. Để e 2 cái về làm nguồn amply.

I m not getting 1.5k 3w resistor, is it ok to use 1.5k 1w or 2w???

[@LongTechnical]

2W ok bro

[@mrmohammad1173]

Hi bro. Can i use irf740 mosfet?

[@ajimattar6891]

How many amp

[@ehsanlion4391]

Please share a details of transformer EE42 to png file in download file🙏
Thanks

[@Amplifiertractor]

Ye smps ka price bro

[@abdurraheem898]

I can't download layout file....

[@EvelioMartinezAndres]

Can you provide diagram please?

[@ajimattar6891]

[@benzimanagbozo3607]

Please can u send me the schematics?

[@awayelektronik9549]

Circuit diagram etd42

[@ehsanlion4391]

Like and comment one😍😍

[@leonardocedeno6377]

porque no 110/220 seria mejor

[@kevincastro156]

Solo se hace un puente entre el centro de los capacitores y una pista de alterna y ya funciona con 110

[@leonardocedeno6377]

[@dipjyotibhattacharyya7296]

Sir can I use 0.19mm copper wire instead of o.3mm..coz it's not available in my place..if yes..then turn ratio will be same as you shown or something else..kindly reply sir..

[@Kozuki_oden67]

Can it be use for amplifier...?

[@LongTechnical]

Of course bro

[@Kozuki_oden67]

Is it ok to use 1uf polyester film capacitor instead of box film capacitor ??

[@LongTechnical]

It's OK bro

[@genalphalyrics8729]

Hey could you design one that uses toroidal ring?...

[@LongTechnical]

I will try
