From the brand
NANKADF is a company that specialises in making DC power supplies. We have our own R&D patent and professional production factory. Standard and strict quality control is our aim.
NANKADF dc power supplies have always been upgraded and innovated in the field of expertise.
Whether you are an engineer in a specialised field or an electrical enthusiast, it is the perfect partner for you.
NANKADF DC POWER SUPPLY
High-precision Encoder Knob: Different from general knobs, this DC power supply has a precise encoder knob. You can press the knob to switch each digit, and then turn the knob to customize each digit in the range of 0-9. Set the voltage or current you want more accurately.
Output Enable/Disable Button: In the process of using the bench power supply, Output button can prevent us from forgetting to turn off the output and causing damage to the load. Just press this button to turn on or turn off the output of the power supply. This makes it more convenient for you to use the variable power supply.
Overcurrent Protection: When the OCP function is turned on, if the load equipment is short-circuited during operation, the adjustable power supply will automatically stop output and send a buzzer to alert the user. Protect the adjustable power supply and load from damage.
Precise 4-digit LED Display: The dc power supply is equipped with a high-definition 4-digit display with data accurate to 0.01 V and 0.001 A. It has constant voltage (C.V.) and constant current (C.C.) modes, which can be switched automatically. You can see the working status indicator on the display. Additionally, you can adjust the brightness of the screen according to your needs.
USB Fast Charging Port: The variable power supply is configured with an 18W fast charging port. No more mplaining about mobile phones or repaired devices not being charged in time. The NANKADF dc power supply allows you to avoid this dilemma. It charges your devices quickly anytime, anywhere.
Compact and Lightweight: The measures of the variable dc power supply is only 7.51 x 3.56 x 5.81 inch and the weight is only 2.47 pounds, which saves more space on your workbench and is convenient for you to carry when you need it.
Customers say
Customers find the power supply easy to use and control. They appreciate its steady stream of power and variable voltage adjustment. Many consider it a good value for the money, describing it as an excellent low-cost switching bench supply. However, some customers dislike the voltage. There are mixed opinions on functionality, build quality, and accuracy.

Power supply
I bought this unit to run my Caswell plating system. Itâs easy to operate and works well.

Good power supply, although 300 watts might be a bit ambitious
Generally, I like it. A good power supply in general and a great one for the price.Don’t try to run it continuously at 300 watts, though!I like that encoders because I hate the separate coarse/fine pots on most power supplies. You can change the encoder step size so you don’t need a separate control. Something I don’t like is the three second delay between adjusting an encoder and transferring the reading to the actual setpoint. I understand why they did this but it means you cannot gradually adjust the output voltage or current.The leads that come with it are cheap to the point of being useless. They use fork terminals instead of banana plugs. The alligator clips are beyond cheap and the jaws don’t stay parallel. The worst part is that the boots are so slick that it is very difficult to squeeze the clips to open the jaws.According to my Fluke 179, the voltage and current calibration errors are both a fraction of 1%It has been a few days since my original review and as of this morning, the power supply won’t go above 25 point something volts. I can dial the setpoint up to 31 but the actual output is only 25 and change. Too bad. I liked it before this happened. Amazon cheerfully sent me a new power supply.

Great little Power Supply with Wonderful Voltage & Current Selection knobs
I need a second low-voltage supply at our ranch for use in bench testing electronics at typical electronics supply voltages levels, sort of 1.5 volts to 18 volts. In particular I wanted to use it to test a rain gauge with LCD display designed to work off of two AA batteries…sort of 3.5 volts down to 2 volts. I wanted to measure the discharge current drawn by the rain-gauge electronics as a function of voltage as the battery discharged, and describe the LCD display brightness and contrast as a function of voltage level. With my other low-voltage bench supply, dialing in a particular voltage in a real hit or miss operation. The course knob always overshoots, then I find that my desired reading is out of range of the fine knob…so I go back and forth several times to get the reading I’m after. The unit was a dream. You just set the knob to control the digit you want to control and it just steps precisely for each click of the knob. In my case I wanted to test in 0.1 volt increments starting at 3.5 volts and dialing slowly down to 2.0 volts. I just set the voltage at 3.5 volts and the knob for 0.1 volt increments. Each click dropped the voltage exactly 0.1000 volts. Infinitely better that my other power supply. The second thing I like about this supply is the second on-off switch on the output…separate from the power on-off for the unit. Another. 50-year-old very-low voltage supply I have has this feature and I use it all the time. With this feature one can set the voltage and current level while the test unit is plugged in and also turn the test voltages on and off without going thru the transients of turning on-off the power supply. Very helpful.I checked the voltages and current w.r.t. my digital multi meter and the agreement was good. However, don’t expect it to accurately measure currents of just a few milliamps. For that I used my digital multimeter.Highly recommended!

Excellent Power supply! Great company stands behind product!
The power supply stopped working after 8 months but NANKADF stands behind their product.They contacted me and offered support to make sure nothing could be done to get it working. Then they sent a replacement of the power supply!Great quality power supply that had a problem and the company that makes it took care of the problem immediately and got me back to working!Top quality product, service and support!Will buy from again!———————————————————————-The power supply was easy to use and provided a stable power source.The meter for the output was slightly off +/- .2 (totally acceptable variance for a power supply of this level)But that was the good.The bad is that it just stopped working! I went to turn it on and pressed the power button, nothing. I checked the power cord, the outlet and the fuse. Still nothing.For the price it should have lasted a lot longer than 8 months!

Failed to work after simple bench test.
I took the power supply out of the box. Nice look and feel. Easy to use buttons. Operationally the knobs and controls worked as advertised in the owners manual. I conducted a simple bench test of a analog clock for a classic car. This clock only pulls .001 Amps at 12 volts. I set the power supply to 13.5 volts because that’s what the car battery is charged to in the off position. The clock ran perfectly and I could see it was each second it was only drawing .001 Amps from the power supply. So I let it run for an hour. Came back to check on my test and the power supply was not outputting any voltage or current. I then read through the owners manual for diagnostic information and there was very little. I replaced the fuse above the 120v power feed and that did not solve anything. Sent an e-mail to their support in China and they wanted me to take the cover off and inspect some of the electrical components. At that point I stopped, put the cover back on and placed the power supply back in its box. Its being returned. I have requested from Amazon another one. Lets see what happens to that one. If I run into the same issue I will post a review again. Not happy with the way the product worked. I do really like the size and voltage/amp range available for the price point. However the product should work or have more power surge features.

I do a lot of DIY projects and need a power supply and this is a good one.
It’s simple. The controls are straightforward, and it does exactly as advertised. Stable output

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

En general todo muy bien, el único problema fueron los cables, que no servÃan y no me pudieron resolver ese problema
