Introduction: Diy Lab Power Supply

Picture of Diy Lab Power Supply

this is lab bench power supply

i use atx power supply as main componet

Step 1: Component You Need

Picture of Component You Need

  • atx power supply(i use 450w)
  • banana connectors
  • switch
  • leds
  • wires(use thickness as per current requirement)
  • wood
  • and some basic componet

Step 2: Make Wood Box

Picture of Make Wood Box

make wood box and connect screws cable clamp

Step 3: Connect Atx Power Supply

Picture of Connect Atx Power Supply

put atx power supply in wood box and connect wire to screws cable clamp

the wire connect according to pin map

Step 4: Diagram of Power Supply

Picture of Diagram of Power Supply

connect all think together as per diagram

and connect all think together on front panel

Step 5: Make Variable Output

Picture of Make Variable Output
  • now make variable output for variable output i use dc-dc converter with variable voltage and current limit .
  • it can output 1.3v to 27v and 3A max
  • connect all componet as per diagram

why 4 potentiometers instate of 2 ??

i use 2 pot for voltage and 2 pot for current that give me small change in voltage and current value

you forgot to add a load resistor for stabilization...

no without load resistor it gives me proper out put but now i connect load resistor for safety

Oh yea, those old ATX power supplies had some pretty stout current capabilities. And they would make a really nice shop power supply. Thumbs Up!
