About: Do you like technology? Follow my channel on Youtube and my Blog. In them I put videos every week of microcontrollers, arduinos, networks, among other subjects. New tutorials on Tuesdays and Fridays.

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 1: Resources Used

• PB-220/140 Patola Box

• 2x 24v 10a Switching Power Supply

• 2x Digital current and voltage regulators

• 2x Analog voltage and current regulators

• 4x 10k pots + knob

• 8x female banana plug connectors

• 2 x 4-way pressure connectors

• Illuminated button

• Hi-link 5v source

• 5v 10a relay

• 1n4148 diode

• IEC connector C14 (power supply)

• 10a fuse

• Fuse holder

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.

Step 9: DPS3005 Digital Programmable Controller Connection

Step 10: DPS3005 Digital Programmable Controller

Step 11: Analog Regulator Connection (chip: XL4005)

Step 12: Hardware Mounting: Connection of the Drive Circuit

Step 13: Mounting Switching Power Supplies

Step 14: Rear Panel

Step 15: Front Panel

Step 16: Plastic Protection Against Short

Step 17: Front Panel Installation

Step 18: Assembling the Fairing and Running Test

Step 19: Source Without Analogue Regulators

    Belo projeto! Poderia colocar ele em versão pt/en aqui, normalmente faço isso em meus projetos pessoais .
