Je recommande tout de même un transfo d'isolation (1:1) à l'entrée !
I'm watching from Russia and it's funny to me over such a primitive ))
It is always necessary not to show ads everywhere, but to archive the scheme. Or show it for at least 4-5 seconds, even on such small stuff.
Without a scheme, this is collective farm needlework ))
Capacitor Reactance converts to Ohms resistance. Here is formula example: 108 UF capacitor limits the current due to Capacitor Reactance on a120v 60hz AC power source. Capacitor Reactance = 1 / (2 * PI * Frequency * UF / 1000000) EX: 1 / (2 * 3.14 * 60 * 108/1000000) = 24.57 Ohms 120 VAC / 24.57 OHMS = 4.88 Amps
👍
Where 4.88 And in such garbage??
These are all old crafts and they were calculated, approximately: 14-15 mF per 1 Ampere of load current.

Fantastic idea Mr Zalpher 🙂 is output voltage accuracy or direct ?
will output directly
Very nice sir ji 🙏😊👍
El potenciometro .hace que varie el voltaje
nice. Thanks for ths idea.. do you have also ideas for measurement cirquits e.g electrosmog ?
elinize sağlık
Teşekkürler kardeşim
Can we use as a 12 volt battery charger
bro. how many amperes it gains.. Please tell. thanks bro
The Ampers is in milliamps
100 MA
Bu güç kaynağı ile kaç amperlik aküleri şarj edebiliriz?
Can you provide the circuit diagram for the same... ???
you are fabulous
Thank you very much for your support and comment.
*LIKE*....PASTI UNTUKMU KAWAN....HEALTHY GREETING ALWAYS....
Terima kasih banyak atas komen dan sokongan.
Just connect the oscilloscope to VCC( DC) output to se the out put waveform🙄😉
If it possible please make auto cutoff for cell phone charger
Voltaj neden stabil olmuyor çok oynak ayarı zor gibi... Emeğinize sağlık
stabil kardeşim ancak ölçü aleti 5-12-30-100 voltta farklı modlara geçiyor ancak pontans hasas evet
HOCAM DEVRE ŞEMASINI ÇIKARTTIM NPN TİP 41C transistörü arduino ile kontrol etmek istiyorum 24 volt 450 mA rs360 tip bir motor süreceğim. su ana kadar trafosuz 24 volt tüm devrelerde sorun yaşadım. 24 volt elde edebiliyorum lakin istediğim amperi alamıyorum. tahminim kutupsuz kapasitörun etkısı var şu devreyi 0-24 arası nasıl ayarlayabilirim bugün iki kutupsuz kapasitor ile motoru çevirdim lakin zener diyot ile 50v 470uf kutuplu kondansatör çok ısındı. ık adet 50v paralel bagladım yine ısındı.. mortorda durmalar oluyor. çinde adamlar 0.68nf tek bir kondansatör ile bu motoru canavar gibi çalıştırıyor. anlamadım. smd sıcak hava ufleyen lehim makinası yapacağim program hazır sensörler hazir. rezistansı optoküplör ile kontrol ettik motor sürücüsünde takıldım.
SUPER

Merhaba karavanıma küçük 220v klima aldım fanı tek kademe düşük üflüyor bu fanı nasıl güçlendirebilirim teşekkür ederim
Поржал. Регулируемый блок питания для мультиметра? Мощность какова у этого изделия?:
Привет, у него выходной ток 100 мА
Благодарю за дополнение.@@ZAFERYILDIZ52
Pot un değerini biraz yüksek tutmak ayarlamada kolaylık sağlayabilir
dip voltajı yukarıda bırakacaktır. 20 k uygun
@@ZAFERYILDIZ52 evet.
this is a disaster voltage doesnt stay precise
Because voltage from ac is flow. 230v voltage is not stable in plug
👍
Zafer какой максимальный ток выдает этот источник питания?
Никакое хорошо если лампочка на 40в потянет
100 миллиампер, братан
Bộ này công suốt được bao nhiêu w.
Có thể rút được dòng điện 100 ma
Woooo❤❤❤❤❤

Dòng ra của nó tối da là bao nhiêu
Good. I want to buy. Where can I buy it?
buy the parts and ask any technician to solder it as in the video
Почему изолента чёрная? Нужно было синей😂
Saya dari Indonesia... kepala saya sedang di SADAP. Ada sinyal gelombang satelit komunikasi di telinga saya.. kecanggihan program alat sadapnya.. membuat saya seperti menderita penyakit skizoferina atau psikotik yang parah.. banyak suara suara manusia yang di pancarkan dari alat sadap tersebut setiap menitnya tanpa pernah berhenti... saya memohon sekali kepada saudara untuk menciptakan.alat penghambat sinyal gelombang satelit komunikasi yang bisa di lekatkan ke telinga saya.. apa yang saya tulis ini benar adanya... tolong bantu saya.. sudah 5 tahun ini.kehidupan saya di permainkan oleh kelompok penyadap.. penyadapan ini di lakukan intelijen militer negara Indonesia...

Nice concept but absolutely no real world use! Very unstable......
Elektrik çarpma tehlikesi var...
