[Review] RD-Tech DPS5020 1000W CV/CC Bench PSU & Metal Enclosure

The products were sent to me by RDTech Aliexpress Store for review.
Here's the page of products that took part in this review.

1. RD DPS5020 CC/CV PSU

2. Metal Enclosure

Output Voltage accuracy: ± (0.5% + 1 digit)                  Output Current accuracy: ± (0.5% + 2 digits)


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:

  • 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 Smile
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.

Due to my limited free time, I haven't gotten enough time to play with the Bluetooth and USB modules but once I do I will certainly be updating this review!

I'm a fan of RD Tech power supplies.  I have a 5015 and 3005 and have used them regularly for years without issue.  Thanks for the review bilakos10.  Would love to hear your thoughts after you get some experience with the data logging capabilities.

Rest assured that I will be posting my findings about the two modules once I get some time to spare.

By the way, what have you been using to power your DPS supplies?
Are those industrial looking PSUs with the metal mesh found in the eBay any good?

Thanks for the review bilakos10.

What I do not understand is how a potentially dangerous device like this (AC current) is sold as a kit.

Both the input and output are DC (not AC) so the device is quite harmless provided that you handle it with caution.

I have the DPS5015 and a 1000 watt power supply. Couldn’t be more happier with the way it works.
Has helped me find a lot of electrical problems before the device is installed and put to use.
The only thing that’s a little annoying is I have to hold the Enclosure when I press any of the buttons, if I don’t hold the enclosure the amount of finger pressure that it takes to push the button will just push the whole enclosure across my table. Maybe I should glue it down to the table Big Smile .
The functions and UI are great though, no complaints. Thumbs Up

I think the enclosure works best for those that stack or have the unit on a shelf. I’m really happy with the DPS3012 I have that faces up, no sliding Innocent

It’s surprising how useful it is. One of the best purchases I’ve made.
