The PSU comes in a transparent plastic box.
As you can see, the same box is also used for other PSU models.
The DPS5020 is seated inside some laser cut foam.
The contents of the package include the following:
- The PSU itself.
- The LCD screen used for controlling it
- 2 x ribbon cables
- 4 x U-shaped crimp terminals
- USB & Bluetooth modules (Both of them are optional)
Here's a closer look at the PCB of the power supply.
No components mounted on the back side of the PCB.
The four white feet are used to elevate the board and prevent accidental shorts.
This is how the INPUT and OUTPUT terminals look.
Each contact is consisted out of two metal plates and a screw.
The crimped wire terminal is sandwiched between the two plates in order to ensure good contact.
Here's the 1.44" LCD display.
The back side of the display contains the two slots for the ribbon cables.
Each slot is marked to help user while connecting the ribbons onto the PCB.
After seeing the basic parts of the DPS5020's kit, let's also take a look at the metal casing.
Unless you can create a good case on the cheap, it's definitely worth spending a few more $$ and buying this one instead.
The case includes all the needed accessories to make a fully functional PSU.
Here's all the bits included:

The case includes all the needed accessories to make a fully functional PSU.
Here's all the bits included:
- 5V Fan
- PCB with built-in 5V supply and contacts for the INPUT
- 2 x low gauge copper wires
- 4 x Banana plug INPUT & OUTPUT terminals
- Switch
- 4 rubber feet
- Plastic feet, screws, U-shaped crimp terminals, nuts
The front panel of the case is where the display and the OUTPUT plugs are installed.
The back panel is populated by the switch, INPUT terminals and the fan.
The fan is mounted.
The fan is connected onto the 5V rail of the PCB.
The switch is designed to interrupt the positive input rail.
To finalize the assembly, the OUTPUT plugs and the display are installed, the PSU is screwed onto the case and all the cables are connected to the appropriate terminals.
Despite looking a bit complicated, the whole procedure is quite simple as it's well documented on the product's page.
Here's how the input side looks.
I used a 90W laptop brick to power my DPS5020 - I know that I am underpowering it, but that's everything I had available at that moment
The input plugs accept both banana leads as well as stripped wires.
Here's the main screen of the PSU.
You can set the desired Voltage / Amperage by pressing the V / A button and adjusting the value with the knob.
The supply will not product any voltage until the ON / OFF switch is pressed.
Here's me testing the draw of a Convoy S2+ with a 12 x 7135 Nanjg driver.
The advanced menu can be accessed by pressing the SET button.
The user can fine tune the output Volts / Amps, set the OverVoltage, OverCurrent and OverPower limits, adjust the display's brightness,
access the data groups and set the default boot behavior.
The DPS5020 is by far the coolest non-flashlight gadget that I have gotten my hands onto.
Since building it, it has come in handy multiple times and it will certainly help me in my future flashlight reviews (LVP detection, precise current draw, regulation etc.)
If you have some money to spare, I would definitely recommend it.
