I got the 10amp model just as a safety buffer. Most of my stuff used on it is 2 to 5 amps max. This power supply never seems to struggle under load and is very quiet.The display is easy to read, and the included instructions could be understood by anyone close-by. Fan comes on automatically when required by settings. It is also variable speed so it is quiet during most loaded operations. A great buy at intro prices for a basic no bones model that gets the job done.

Great power supply for the occasional user. Easy to use. I purchased this model based on a review of the unit I saw on Youtube. The reviewer was impressed with the build quality of the electronics. I can't tell you how many times I have used this unit to test things, especially LED's or battery-operated electronics. A great little tool and a must if you do any electronics testing or work.

Style: 30V/10A-3-Digit DisplayVerified Purchase
Very impressed with this thing, and NOT just in a "meh, good for the money" kind of way. It's an awesome unit! Smaller than it looks in the pictures, easy to find a home for it on a crowded 'operating table'. Great troubleshooting tool, saves a huge amount of time, and 30V / 10A is a hefty chunk of power for running whatever project you're building or fixing.

Nice quality metal case, smooth controls, unit doesn't feel cheap in any way. Voltage regulation is right on the money. Coarse and fine adjustments for voltage and current limit, very easy to use. Thumb screws on the output terminals for bare wires, or remove the screws and use any probes with banana plugs.

I would buy this again, and definitely recommend it.

Great little device. I gave it a workout with a motor running 6a 13v......no problem.

Pros - This is a very nice compact light weight power supply. (30V x 10A version). The controls give very smooth and fine control of voltage and current. It is very easy to interactively change from voltage to current limiting.
Cons - The fan is a little noisy on high speed but is automatic variable speed so on most of my applications it is off or on low speed and quite quiet.
- The documentation is poor, if you do not read carefully you might believe that it is necessary to turn off and on to switch from voltage to current limiting function
- The knobs should be labelled
