Introduction: Super Low Cost Source
Did you realize that it’s possible to make your own source and actually spend a third of the amount you would need to buy a ready-made one? This source is with an output of four current and voltage regulators, two of them digital and two analog, which operate from 0 to 24 volts with a maximum load of 5 amps. I'm going to show you this today, which is an assembly that carries the DPS3005 module. This subject is a source of current and digital voltage, and it is a monstrous utility.
In this video today, we are going to talk about two source models. One can provide four different voltages. We also use a connector that is made for a speaker, which I think is simply great.

Step 3: Taking Advantage of a Burnt Out Equipment Cabinet
Here, I want to show you an example of a burned out piece of equipment that I have. This is a symmetrical simple source that measures up to 30 amps.
Step 4: Schematic: General Circuit
Here, we have the general scheme of the fourfold source. But you can adapt it to make it a double source, if you prefer.
Step 5: Optional: Capacitor Filter
Here are three categories of capacitors you can add to your project and filter the output of your source.
Step 6: Drive Circuit
In this image, we have a simple schematic of how to make the switch turn on the relay. And the relay then turns on the 127V to the sources.
Step 7: Relay Connection
Step 8: Power Supply Connection
Here, I have the source scheme I used, with Phase, Neutral, and Earth.
