Certainly, You should utilize 20K pot. But, you'll want to increase 20K resistor in parallel using this type of 20K pot. See in the picture under, the overall resistance is 10K a similar inside the circuit.

Reply thiago September 1, 2019 at 12:forty seven pm Hola pessoal, ótimo projeto porem na criação da PCB o designer do transistor tr2 a pinagem esta errada!!! o transistor BF422 (ECB) e na PCB esta (EBC) o que ocasiona o não funcionamento do projeto ( o LED de proteção fica acesso ao ligar ) e só funciona se você segurar o botão de reset!

Each on the transistors proven inside the diagram must be rated with a breakdown voltage of at least fifty five volts.

This publish explains the Doing the job of a variable DC electric power source circuit which has an adjustable voltage array of 1.2V to 24V and existing up to 5A. it's got a lot of functions like small-circuit security, a lot less ripple issue, output voltage tolerance, here etcetera.

Incidentally the above energy supply design and style is not really my style, it was performed because of the elektor electronics engineers.

I would want to consist of digital voltmeter and ammeter and also an LED indicator to show when electricity is on. Connecting the voltmeter is straightforward.

Is it possible to ship the PCB layout You should an organization and possess them make the PCB? Wasn’t confident if This can be copyrighted or not. If this can be done, what file format might be necessary? JPG, PDF? I feel that you mentioned you made use of EasyEDA.

Thanks for that speedy reply. I like to see things simulated ahead of diving in, but I assume I should really just split out the soldering iron.

for your max output current you are able to just use Ohm's regulation to Learn how A lot the resistor can deal with….

Thanks quite a bit for your reply. I comprehensively checked the circuit and uncovered that one of the 2N3055 that I utilised as Darlington pair was defective, so I eradicated it, and employed only one for the reason that I couldn’t quickly buy A further a person. astonishingly, it labored perfectly. I also altered T2 and T3 to 2N2222, and R3 to 1k. every little thing labored completely with none on the elements heating up or burning out.

The LM317 is usually averted absolutely In accordance with me. I'll consider to analyze a lot more these types of regulators and let you know, if at all possible.

P1 is often a potentiometer that controls the peak output voltage, though P2 is useful for setting the minimum output voltage from the power offer.

C2 is for sound and might be 1uF. The ratio of R20 and R23 set the output voltage. they might be two fixed resistors or an adjustable potentiometer.

Dera swagatam thanks for all ur variety. But im nonetheless have problem including volt amp meter electronic on this schematics. Owh i such as calculator on this cellular Model but i cant discover the search bar on cellular version.
