DIY Variable Power Supply With Adjustable Voltage and Current
Hey Guyz, This time I'm making a variable bench power supply. This is the most useful equipment for a hobbyist and DIY maker cause while making or testing circuits, it needs different values of voltage and current. That's why every DIY maker must have their own bench power supply. Now I'm going to show you how to build an awesome variable bench power supply. So take your tools and let's get started :)

I'm using here LTC3780 DC adjustable buck and boost converter. which is an amazing module. It can deliver DC (1-30V) and up to 10A current depends on your input power source, in my case I'm using DC 12V 3A input power source. I easily get continuously adjustable output voltage (1-30V) and current (0-6A), which is pretty enough for circuit testing and other things. I'm also using 7805 voltage regulator IC for 5V constant voltage and current.
This Power Supply Has Following Features:
Input Voltage 12V DC.
Input Current 3A.
Output Voltage (1-30V) Continuously Adjustable.
Output Current (300mA-6A) Continuously Adjustable.
Output ripples 50mV.
Constant Voltage And Constant Current.
Additional 5V Constant Output.
Short Circuit Projection.
We need these following parts to build the power supply. I bought some from online and some from the local store.
Parts List:
LTC3780 DC Adjustable Converter
Digital Voltmeter Ammeter Display
500k & 200k Linear Potentiometer
12V DC Fan
7805 IC For 5V
12V 3A Adapter
100uF & 10uF Capacitor
1N4001/1N4007 Rectifier Diode
Banana Socket 4ps
Knob 2ps
DC Switch
2.1mm DC Jack Connect
Wires
HeatSink
Wooden Blocks
PCB board
4mm Acrylic Sheet
Tools List:
Glue Gun
SuperGlue
Sandpaper
Mini Handsaw
Soldering Iron
masking tape
drill machine
Rotary Tool
spray paint
I'm using here acrylic sheet to make the enclosure of my power supply. This is an amazing material cause it is easy to cut, bend and sand. it's also so affordable. You can use the acrylic sheet to make your own power supply. So let's get started.
First, take a measurement of acrylic sheet.
Cut the acrylic sheets according to the marking.
Place the voltmeter display and mark it.
Next cut the marked section with a rotary tool and metal file.
Again mark the areas for air passing
Cut the marked area using a mini hacksaw.
Take the measurements of dc socket, dc switch and dc fan, then mark it.
Drill the holes and smooth the edges with a metal file.
