DC Power Supply Variable 0-30V 0-10A, Adjustable Switching Regulated Bench Power Supplies with Encoder Corase & Fine Knob, 3.6A USB & Type-C Quick-Charge, Overcurrent Protection(OCP)

Works well enough. It's exactly what you would expect from a basic power supply at this price. Relatively accurate current and voltage setting and I appreciate that it shows you watts instead of having to calculate yourself. I ran the 30V 10A unit overnight at the full 10A output and it did it with no problems.Minor Complaints:The beep sound is a bit loud, but I think it's a piezo buzzer and you can probably just open up the unit and put something over the hole on the buzzer to lower the volume. Also there isn't an enable/disable output button and instead you have to turn the whole unit on and off which involves it booting up (takes about 3 seconds) and making a loud beep sound. Many load conditions will cause the switch mode supply inside to create audible noise.Overall I'm pretty happy with the product since it powers circuits perfectly fine with no issues and that was all I really needed.

It's a great little desktop variable power supply. I purchased this mostly for balancing the cells on my LifePo4 batteries. It has worked flawlessly. Both course and fine adjustments work smoothly and one increment at a time. To balance my battery cells, I pull the battery down to about 80% and then connect the power supply. I then adjust the supply to apply roughly .250 amps and leave it there until the BMS shuts off the charge. A useful added feature is the USB ports, which work well. I have cranked it up to 10 amps to speed the process by bringing the battery voltage to about 13.2 volts and then turning it back down. In doing so, the fan automatically comes on and runs for 30 seconds or so, then shuts off. Some reviewers mention that the fan is loud; it is. However, I do not find it to be excessively loud, and in my mind, I want it moving some air so I expect it to be audible. The more it blows, the better it is. It moves a lot of air, it does not have to run long. I have no problem recommending this power supply.

You never know you need a powerfully that you can adjust, until you need one. This works very nice..used it on alot of troubleshooting stuff.

This power supply is OK (noise level is about 150 mV p-p).The only drawback is that the posts do not have holes in them to feed the wire through.Without the hole, it is a bit difficult and takes more time to wrap the wire around the post.

Got this for my teenage son for Christmas as he has begun to show interest in electronic projects. This has been s reliable and affordable option for powering various electronic projects. It offers stable voltage and adjustable current, making it versatile for different needs. The design is compact, and the display is clear, showing both voltage and current readings. It's easy to use and works well for hobbyists or professionals needing a consistent power source. Overall, it delivers good performance at a reasonable price, making it a solid choice for those in need of a DC power supply.

No hice grandes usos de la fuente, probé algunos componentes electronicos e hice algunas pruebas. Las mediciones fueron bastante exactas. Buena compra

Nice power supply for my use. One of my hobbies is making micro machines. Metal lathes, milling machines etc. I use 12- 36vdc motors and this power supply is handy for testing/running my creations. I can even run a treadmill motor with sufficient power to turn steel and aluminum on a small mini lathe.

I needed to fix something at the office, so I ordered this inexpensive power supply. Something told me to check it out at home before I brought it into the office. When I first turned it on, I was able to vary the voltage, but when I put any kind of load on it, it tripped the circuit breaker. I tried this a few times from different outlets and it did the same thing. I have a device that is a resettable fuse so I connected the power supply to that so that I wouldn’t have to reset the circuit breaker each time and determine what was going on, but the power supply shorted the 120 VAC so fast it tripped the circuit breaker through the resettable fuse, which I’ve never seen before. Clearly, this power supply was defective and in fact, dangerous. I contacted Amazon and they arranged to have another one sent a few days later and guess what? It did the exact same thing. I then ordered a little bit more expensive power supply from another company, and that worked as expected. The moral of the story, don’t even think about buying this power supply.
