Hello, I come from Vietnam. I find your product perfect and beautiful. I am also planning to make a source set from your idea. Thank you, your instructions are very detailed and have clear diagrams!
I have a challenging project that I would like to assign to you. It involves creating a bench power supply that can be controlled using the DAC pin on the ESP32 microcontroller. To my knowledge, no one has made this before, and I believe it will require your unique set of skills and expertise.
Hi Debashish! Love the video and easy to follow design. Have you considered making a USB-C powered version instead of a DC jack? There are many Apple/Microsoft/Samsung laptops these days which have 60W to 100W power supplies with USB-C. It could be cool to power the bench supply from that. Many thanks!
Hey buddy one more question: In the description you gave the wires as 20 AWG but in the video you are saying you are using 24 AWG wires, may I kindly ask you if there is any problem if we use 20AWG as mentioned in the description? Please reply back to me.
Hello Debashish! This was a great project but I was just wondering if the volt- amp meter is accurate enough because I've heard they are quite inconsistent with readings.
Thank You Utsav, you are correct, especially the inconsistency is in the current reading. I have also noticed it. I will search for a better meter for the next version.
These volt/amp meters can be quite easily calibrated if necessary. They have onboard potentiometers. Also additional resisters can be used. There are videos on this.
Maximum 75 watt.. That restrictions is not good if you are testing anything above that power rating. And other things like there is a Maximum V difference among Vout and Vin that allows the circuit to run. That needs to be taken into consideration.
NO! The voltmeter wiring is not sufficient it would result in incorrect measurements, instead you have to connect the orange wire to the output + of the Xl4015 module and connect the red wire to the input of it. If you wonder how will you get negative voltage,it will be supplied by the ampere wires.
Very nice, clean and understandable project 👍👍👌 but I have one question which is - is this able to run a peltier module air conditioner ? Please reply soon.🙏🙏
@@opengreenenergy yes, it's TEC -12706 (12v - 6A) peltier module. Please reply as soon as possible because I am also working on this project and want it to complete in next 1 or 2 days.🙏
@@opengreenenergy ok thanks for your reply.🙏 I will use another high current module so, can you suggest me which one would be the best for TEC - 12706 (12V-6A) peltier module?
@@opengreenenergy i know each is for volt and amp.. But y are we using it.. If we switch off any of the switch the output will cut off right.. By the way thanks for your response
@@paraschaurs Without it, the output port is always live, during connection of load there may be chance of sparking if you set to high current. It is better to connect the load offline first, then switch it on
Current limit means a soft short circuit protection. If you set a low current limit before enabling the output then it cannot pass a lot of power without hitting the current limit.
Hey buddy I tried out your experiment, exactly the way you have done it except for the Plastic Box. But the experiment was a total failure. It shows Volts but Amps are all the time 0.00 even if potentiometer is turned nothing happens to the Ammeter. So sadly, your experiment HAS FAILED with me. I don't know why, when I did everything as shown by you, even though you skipped parts of the tutorial, I managed it. But still failed.
Buddy your idea is good but your explanation is too fast. To be honest with you I don't have much knowledge of diagrams. But you are too fast in showing what you are connecting, and it is difficult to know which wire is where. I am all confused with it. Can you show slower and properly from scratch which wire goes where? Some you have shown slowly and perfectly, but some are quite confusing with your speed of narration and doing.

Nice work, very proffesional
hello Dutta this is well details video for someone like me who not knowledgeable on electronics, thank you
This is the best video of variable power supply...👍👍❤️❤️
One of the better design and utility value
Thank You.
Nicely made video and excellently detailed instructions. Many thanks.
Glad you like my project
Nicely managed to explain the entire video in a very easy way. Great job. Nice video.
Glad you liked it
Good job 👍🏻👍🏻👍🏻 🇮🇳 || Kuki
Suitable for small electronic repairing and diy👍👍
Excellent video with great explanation. Thanks for sharing.
I like the way you explain ,keep it up !!
It is not power supply, it regulated dc dc converter!
thank you... ugh, some ppl
Ii is called power supply
You can ad some step up
This is same too bro. Vut this is mini psu .if u want to make big voltage and amphere, u can use trafo(transformator)
neonquai don't be rude
Good DIY Mini Lab Power Supply..
Thank You.
when the input voltage varies from the solar panel, what would happend the output?
Thanks . The best. POZDRAV IZ SERBIE.....

Really good suggestion. I will make one in my upcoming video. Thank you
Nice project. Very useful.
Thank you
You need to set the voltage and amp before you charge the any batteries not after you connected 😂 to the batteries 😝
superb job
This good idea, and thanks dude for sharing
In you diagram the LX4015 module is different with different measures than the one you are actually using. Can you please explain why it is so?
Thanks for sharing
Well done! I notice you use a switch near the output side. Is this the safest way to set constant current? Thanks!
Excellent
Thank you
If you want 1.5 or 2 volts on the output, how is the volt/amp meter powered?
You need to conect it to the input power of the converter for it to turn on

Is XL4016 CC and CV? Can I use XL4016 instead of XL4015?
Good day sir your project is wonderful and I'm amazed. I have a question can I use in the input a power bank to power it up? thank you!

Thank you
How many Amps is the Fuse? Can you please tell me the Fuse Amps buddy?
You can use 6-8A

Hey bro can use 24v 5a power supply
Can I not remove those trimpot? Is it okay if I use it?
Volt meter voltage connection are wrong.
Volt meter should be connected to output of buck converter.

Hi!
May I ask you that what kind of fuse did you use?
How many Amps must have my fuse? Is 4A ok ? Or more?
It depends upon the amount of current you want to draw from the output. The fuse rating = Max current x 1.56
@@opengreenenergy so if I want on autput 3A I must buy somsthing about 4,5A ?
Can I make it with out a fuse?
Can we use an input adapter of 12v.if we can use then at what ampere should we use it.
As per your requirement
@@opengreenenergy since ur using a 12v adapter wat is the difference in the ampere in adapter output and module output. Are both of them the same

Hi, Is there short circuit protection at input and output?
Current limit means a soft short circuit protection. If you set a low current limit before enabling the output then it cannot pass a lot of power without hitting the current limit.
Hi buddy , can i use 5V as a input it means a phone charger
buddy please reply as soon 🙏🙏
No, this is buck converter it can reduce volt but not boost volt.
What is the maximum output voltage that can be supply
Nice

Amazing ideal...Peace
What the difference between XL4015 and XL4016?
Can I first use boost converter to boost voltage to 24V then connect it to buck converter to regulate it?
Yeah I am planning to do the same just check the max voltage of the buck converter
