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.

A switching PSU, but lighter than I was expecting. It works GREAT! It is a fully adjustable PSU. Pretty amazing technology for the very low cost. Works fantastic for my application (high current sub-woofer amp). I would highly recommend this for "bench" use, or otherwise (CB Radio, HAM)...or just for a test repair PSU. Fantastic!

Works properly. Great price. The location of the terminals makes it difficult to slip in the connection. So I just attached it to a piece of wood to elevate it off the table top.

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.

Works as per needed love to use this unit would buy again.

This is AWSOME !

MUY BUENA CALIDAD, PRECISION EN LA INDICACION
