This power supply has a very impressive amount of functionality and quality for the price. The voltage and current displayed on the readout is very accurate. I checked with a multimeter from 10mV to 31V and also at various steps in voltage. Same for current from 10s of milliamps up to the max.
So it's accurate and 30V 5A is more than enough for many projects, no complaints there. In terms of user interface, I think it's fantastic. Really happy with how simple and intuitive it is. There are no weird additional functions that require you to hold buttons and input something; all the functionality is clear and you don't have to read the user manual to understand what the buttons do.
The memory functions work very simply; whatever memory setting you have selected, any changes you make are stored there. It's a bit of a bummer that if you change something, you have to change it back instead of being able to just save one setting and revert, but I appreciate the simplicity.
The lock, over voltage protection, and over current protection is very easy to use and self explanatory. You need to hold the lock button for a couple of seconds to turn it on and off. With the lock on, the buttons and knob do nothing. Great for making sure you don't fry something by accidentally changing settings.
One thing I really like about the user interface is the audio feedback. A lot of people don't like it when their equipment beeps with every button press, but I think it's nice to know that your button press registered, and this power supply does it really well. All of the buttons make a beep, and things like using the lock or turning the unit on produce a different beep. The knob (which is a rotary encoder that is not continuous but has bumps, not sure what you call that) makes a clicking sound when you increment or decrement (is that a word?) a digit, which feels really nice.
Inputting a voltage/current is really quick and easy despite there being no keypad. For the price, it's completely acceptable that there's no keypad, and the rotary encoder and left/right buttons work just fine. The audible feedback and clicks in the rotary encoder make it easy to really quickly dial in a value.
There is software included as well, and it's pretty good. I'm not completely sure, but it seems like it's just a labview program (though I don't know too much about labview, I am just a lowly undergrad EE student). It does install some national instruments stuff during the installation process. It's very easy to install and use, and you just connect to the power supply with a COM port. You can do anything on the software that you can do with the physical buttons, with some additional functionality. With the software, you can output a sequence of voltages at any time interval. You can also record the voltage and time at any interval and save that data to a text file, which you can import into Matlab or whatever you want to use. It shows graphs of the current and voltage as well. All this stuff is great for plotting I-V curves and seeing how much current your device is using over time. Cool stuff.
Since it connects with a COM port, I'm sure you could get it to work with your own Labview programs, matlab stuff, or any other applicable software. I used the USB port (cable is included), but there's also a serial port which is cool.
My one complaint with the software is that the buttons for quickly recalling set voltages and currents are filled with some seemingly random values and don't save what you change them to when exiting the program. Weird stuff.
The connectors on the front accept banana plugs, or bare wire. They seem like pretty nice connectors and all my banana plugs fit well. The included leads are perfectly functional, although the banana plug portion has a screw and an extra hole, so not sure what's going on there. They feel a bit weird. But who cares, you're probably using your own leads anyways.
Overall, there's nothing I can fault with this unit. It seems like all the things I've seen in reviews on youtube have been fixed or improved, and everything is high quality and easy to use. I'm very happy with this unit and the price I paid for it.
I normally don't write lengthy reviews like this, but I think this trend of inexpensive but high quality equipment (like the Rigol DS1000 series scopes) is really important for students and beginners like myself. This power supply really stands out to me as a great bang for the buck for an engineering student on a budget.

Style: KD Series - 5 AmpVerified Purchase
Easy to use compact supply for the hobbyist bench. Actual dimensions are approximately 10.5" deep X 4.4" wide X 6.5" high... dimensions stated in the description are incorrect (may be that of the box).
I bought 2 of the supplies so that I might work with circuits that require + and - voltages. The two units stack nicely and take up very little space on the corner of my workbench.
While voltage metering is quite accurate, current readings may be a bit off on some units. In one test, I set up a 1 amp current limit on both supplies, and connected them to 3 ohm 5% power resistors. Current delivered to the two resistors, measured with a Tektronix DMM850 was quite close to the set value, measuring 1.003 amps from the upper supply in my stack and 0.994 amps from the lower unit...very accurate indeed! However, the *current reading* of the upper unit was not as accurate, indicating that the supply was putting out 1.062 amps, while the bottom unit was very close at an indicated 1.001 amps. This is perhaps not quite "lab grade" performance, but good enough for most hobby applications.
I did discover one weak point in the protection scheme of the unit... while it is well protected against shorts and over temperature conditions, one must be very careful not to reverse connect to a battery capable of delivering much current. When charging and testing an 18 volt B&D battery pack, I accidentally reverse connected one unit and killed the output... it did not reset even with a power off cycle. A protection diode in the output of the supply had shorted, which did indeed protect the supply from distruction. After the diode, a 1N5480 was replaced, the unit functioned perfectly, but I might not have been so fortunate if I had reverse connected the supply to a higher current source, such as an automobile battery. Fyi, the protection diode is located on the front board very near the output terminals, so about 10-15 minutes of disassembly is required to get to it.

Almost everybody had some kind of issue with all pro KORAD models, which is kind of absurd. I wanted to examine one myself and the one with the less "problems" was this model "KD3005P" with the two push and turn buttons.
Also I wanted a connection with my PC so I could have a log of my work with it.
This model is really awesome! No complaints by me -whatsoever- . I'm very satisfied with it in many ways..
It has a good programming inside which helps a technician (among others) a lot.
This model has a three way use.
First of all you can push the "Voltage button" and select each digit separately.Same with the "Current" button.
Second, you can lock your adjustments so no accidental turning will increase or decrease any voltage /current setting.
Attention! (The following will help a lot of users of "KD3005P" model):
First testing: You will notice that you can place your desired voltage power but when trying to adjust the current the screen returns to "0000".
The reason is because the PSU does not have any load so be aware that your current setting has been memorized by the unit but will not work until you put a load on it. The best way to test the unit is to connect a lamp (within 0-14V) on the leads.
Another awesome feature is the USB connection to a PC. You'll get a software that can handle the unit completely. Plus it has an 'ON'/ 'OFF' feature. Simply use your keyboard to set the desired voltage /current and press "Enter".
On the right of your software screen you will see two screens where you can monitor the voltage /current of your PSU.
Last but not least the unit has LEDs in front that can show you when your settings are "locked", the Over Protection Current aka. OPC etc.
For me it's a very helpful unit, and I'm very happy to have it on my bench.
I totally recommend it!
