Adjustable power supply ⚡️ (Quick and Easy, # 16)
Hello!
We, like many homemakers, often lack an adjustable energy source, but for some time we were able to compensate for this shortcoming using various sources, batteries, USB chargers, 12V sources, etc. Unfortunately, not all these methods are particularly convenient, especially when there is a need to precisely select a certain voltage, or even more so limit the current, in order, for example, to charge the same batteries. Looking through the expanses of the well-known Chinese store, our author came across several modules, collecting which you can make a very simple and reasonably priced adjustable power supply.
At the output, we can get from one to 24V and current up to 5A.
To create, we needed:
• Module 2in1 XL4015
• Power supply 24V 5A
• 10k ohms multi-turn resistor
• Potentiometer is also 10k ohms
• Cooler 40x40x10 with a working voltage of 24V
• Several switches
• Some silicone wires 20AVG
• Power plug
• And we used the JST plug for the output, you can use any other option such as quick-release terminals or something else.
• Foamed 3mm PVC plastic
• Drawing to create a case: https://drive.google.com/drive/folder...
