You prolly dont care but if you are bored like me during the covid times then you can watch all the new series on instaflixxer. Been watching with my girlfriend for the last months xD
Thanks for the video! I have one concern though, I have the same voltage and current regulator as well as the 10k Ohm potentiometer but when I soldered the potentiometer to the regulator and started turning the knob, the voltmeter is only showing voltage up to 4.5 volts and I have turned the know all the way to the right. I connected the wires (1, 2 & 3) properly per your instructions. What could be the problem? Please advise. Thanks!
Your power supply looks great, but can you tell me how the potentiometers would be connected if I were to add a third potentiometer to regulate the fine voltage adjustment?
Probably many ways to do this. You could add a lower value potentiometer wired as a variable resistor in series with the voltage potentiometer. For example a 10k potentiometer in series with a 1k variable resistor.
Great video. I bought the same SMPS. But when I checked the DC section (24v side) using a tester ( to make sure there is no electric shock), it is glowing very bright. Have you experienced this in your SMPS?
Hey there. I'm just getting to grips with the idea of a floating power supply. I've had the idea of constructing two of these into the same case and using it as a makeshift dual polarity psu, but I'm worried about connecting two unisolated grounds. Am I thinking in the right direction? Or would there be a better solution entirely? Awesome tutorial!
You could build 2 of these to create a split supply. You have to make sure that they are isolated(floating) power supplies. That is isolated from mains and from each other. In this case it is better terminology to say common instead of ground as ground implies a connection to earth. The mains ground/earth should be connected to the case for safety. The 2 power supplies could then be connected in series to create a split supply. Many older lab power supplies were built in this fashion. They would have isolated pairs of outputs and a separate ground/earth terminal. They came with metal connectors that you could connect the outputs to ground your common output or connect outputs in series.
If it draws 10A at 230V then you have another problem with the circuit. Because none of these components can handle 2,3kW. EDIT 13.01.2023: You forgot to say 4:05 that it should be the same resistance in the big potentiometer than in the small blue one.
ts the first video that show how to connect potentiometer multi run correctly instead that preinstalled, congratulation and a new subscribed
I like your details styles ❤️ from Pakistan 🇵🇰

@Kyson Jaxon yup, I have been using InstaFlixxer for months myself =)
Best variable bench power supply video yet! I like your explanation style well done!
Thank you
Great video and your English is pretty good.
Thank you!)
very nice expression and application.many thanks.
Amigo felicitaciones !!!
Excelente video y hablas muy bien el ingles ...!
gracias, tuve que entrenar mucho :v
Well explained..thank you...
Шикарная идея с рисованием цепей на столе!
best explanation ever. thanks a lot
Nice job... Congrats...
Waiting for part 3
Fantastic video!
Thank you, for the extremally well presented, and detailed video, I liked and subscribed, so I see more of your brilliant videos.
Thanks!
Bro i love this💓
Waiting for you
Pls do not be late
Done!

waiting for part 3 ☺️
Great video !!!!
Very nice thanks
Great video , thank you. I realize the same project, but i have a probleme, i can't changing ( vary ) the intensity O_o . Anyone know the probleme ??
bravo !
Nice work
We're still waiting your #3 & #4 videos. Eee send please...!
Done!

可惜只能給您一個讚
Good bro
Good day sir, i wondering what cable sizing that you use start from 3 pin power cord to ac-dc module and from ac-dc module to XL4016 module.. Thanks !
Could you also test the constant current feature? I felt that on CV was tested.

Did you check the input voltage to the buck converter? Also please check if any of the pot terminals are open

hi can I use a regular B10kpotentiometer
waiting for your reply
Thanks
Can I use a better powet converter 220V 36A to 24V
Nice share ...
Great video.

it is weird

Can use as voltage injector for laptop repair?
what happen if the potentiometer change to 20k ohm ?
which one is logical;
1. to use fuse before 220V power switch
2. to use fuses before each outputs (3.3, 5, 12v etc)
As the variable unit ostensibly has current control, stick a fuse between mains and the power supply (as is done with the chosen plug

Can I ask why do you connect 12v to k1 on temperature controller ?
the relay connects and disonnects K1 with K0, so I provide 12V to K1 for the fan
is it working for laptop testing?
0:23 wow..save the money if I can do a magic..from Malaysia
Are both potentiometers 10k ohms? Thanks
Yes
Hi
its working great.. poofff :)))
