Introduction: Super Low Cost Source

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.

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
