DC Power Supply Variable, Bench Power Supply with Encoder Adjustment Knob, Output Enable/Disable Button, Adjustable Power Supplies with USB Quick-Charge, Short Circuit Alam (30V 10A Black)

Very compact, easy to use.

User friendly and nice,very good product.

I got this for a van build that I wanted to test out circuits and equipment for 12v and 24v before I have all the systems wired in. It works great for my dual voltage needs and I’m sure I’ll use it for other projects. It’s really small, lightweight and easy to use. FYI I couldn’t tell in the picture but it does come with a good set of test leads that have clips to attach to your equipment wires. No need to buy extra like I did.

Que es fácil de usar y no se calienta

El producto no sirvió desde un inicio la devolución tarda demasiado tiempo, pensé que al ser un producto importado tendría que pasar por algún tipo de control de calidad el cual por lo visto fue nulo

Just got it, so take that into consideration when reading this review. However, after opening, powering it on, and spending an hour putting it through some initial testing I am VERY happy with this purchase with the exception of one itty-bitty issue (see last paragraph). Obviously time will tell, but it looks and feels like a quality unit. I purchased the 30v-10a unit and after measuring with a good multimeter, the NANKADF accuracy is dead-on below 15 volts and within .005 volts at higher voltages. That's more accurate output than a wall-wart and most PCB power supplies (7805, etc). The encoder knobs are wonderful and let you dial in the voltage/current level you desire easily and error free. I did not find the audible "beep" when turning/pressing knobs to be either loud or annoying as others have suggested in their reviews, however you can disable this although I found the included instructions a bit confusing. 1) Press the output button continually until the unit goes into setting mode. 2) Press the VOLTAGE button until the AMP number shows "4". 3) Turn the VOLTAGE button until the WATT number shows "0". 4) Press the VOLTAGE button until the AMP number shows "6". 5) Press the VOLTAGE button once more to save the settings and return to operational mode. My only complaint is that after selecting and setting the 4th digit for both the Voltage and Amp displays, the unit automatically defaults to the 3rd digit for subsequent adjustments when it should remain selected on the 4th digit. For example, if I want 25.64 volt output, I select and set the first digit to "2", select and set the second digit to "5", select and set the third digit to "6", select and set the fourth digit to "4". My next turn of the Voltage knob should either increase or decrease the "4" in the fourth digit because that was the last digit I selected. However after a 5 second delay, turning the knob changes the value of the "6" in the third digit and so I have to press the knob moving through the display to get back to the fourth digit to adjust it again. While I don't anticipate spending a lot of time adjusting tens of mV, it is nonetheless a little aggravating.

Took a min to get used to how it works but once that min was over it is pretty cool. I haven't tested it to full capacity yet, but so far at about 4 amps it stays regulated quite well. The digital readout seems accurate according to my Fluke meter. I really like the output button. It allows you to set up the voltage and current and then turn on the output. The current limit seems to work well. If I find it other than great along the way I will update the review, but for now, I think it is good value for the money.
