Wow... I'm glad to find this video. It's easy to understand for me as dummies. 😁❤️👍👍

@jp-um2fr 6 лет назад

I have just found you channel and I find the power supply build very handy as I have also bought this kit. I think I will use 2 multi turn pots though. Mind you I do have to get it to work first. Maybe I should get 2 kits. Regards

@KristianLaholm 6 лет назад

2 kits i always a good thing :) You can find it on sale at Banggood right now www.banggood.com/0-30V-2mA-3A-Adjustable-DC-Regulated-Power-Supply-DIY-Kit-p-958308.html?p=AR22132858920201510H

Thank you for its easy when you know how the fine adjustment will work well thanks so easy Many thanks, Bob - UK

Hi.. Great vid.. new to the Channel .. do u have a wring diagram for the 2 extra pot you've fitted ?? Dave UK.

There is the simplified description I did in the video at 5:46 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wpvxlcn7kVk.html

@yangtse55 5 лет назад

I wonder if one could somehow replace the pots in the circuit with mosfets and use shaft encoders and logic ...

@KristianLaholm 5 лет назад

I'm not the one to give the right answer to the question. But I see a problem if you are going to control a mosfet from a microcontroller, it will be using PWM for the analog signal.

some one have such issue with 1v it can't push than 0.7 amps ?

@newvaper3794 3 года назад

can this also be done with the amperes? like a fine adjustment for amperes? thanks for the video Krisitian.

@KristianLaholm 3 года назад

I haven't tried doing the same on the amp setting but it should be possible, the pot setting the current is also a voltage divider if I remember correctly. I haven't tinkered with the circuit for some time but still use it to power test projects :)

@@KristianLaholm thanks for the information...Keep Safe...informative video.

@newvaper3794 3 года назад

got it to work Kristian...yeheyyy!!!...thanks again for the video....just did it on the voltage side...keeping the amperes as is...thanks again.

@ohmedarick1 7 лет назад

Thanks for the explanation on the dual potentiometer. Can you send me or direct me to the get the schematic of the power supply. Thanks again

@KristianLaholm 7 лет назад

On Banggood's product page below the video there is a "English Manual", on the last page you'll find the schematic. Link: www.banggood.com/0-30V-2mA-3A-Adjustable-DC-Regulated-Power-Supply-DIY-Kit-p-958308.html?p=AR22132858920201510H

@Giovanni2862 3 года назад

The schematic has a 10K potenziometer

@patrickvaz2002 3 года назад

Hi, My output voltage is only 26v, any reasons, I should be getting 32volts correct

@KristianLaholm 3 года назад

Check the voltage after the rectifier (across C1). And there is a possibility that if you have run on a to high voltage that the op-amps are burned.

@patrickvaz2002 3 года назад

@@KristianLaholm thankyou for the lead, will do

@jp-um2fr 6 лет назад

Come to think of it I prefer your 2 pots. I bet every time you want to use the thing the multi turns are at the wring end. I suppose you could have 2 pots AND a multi turn. I'm joking - I think. Very useful video's - thank you.

@KristianLaholm 6 лет назад

The PSU with the most pots in the end is the winner :) Good luck with your build :)
