The plastic cover over the adjustment screws was missing. HOW do I get the right covers ?This is VERY INCONVENIENT: The USB connector power by default is OFF so on each power up the menu to access and turn on the USB power has to be performed.Good build quality.

Looks exactly like pictures. I needed 3 amp continuous and most regulators are 1.5amp. Works great for using 15-22volt airplane lipo batteries for 12v needs. So far haven’t needed to add fan for 5 amp use but good to have option or add for safety margine. Good quality clear case and i like display and can shut off once I verify voltage and current levels. I like current regulation in case of liad mishap instead of damaging battery, wire, etc. great value.

This unit has been working fantastic for a few years now, but... The USB port is tied to the output voltage. I have mine set to 24V to power a PLC, That means the USB port is 24V also. USB ports are normally 5V. If you plug in, (say your phone), and the output is set to any voltage other than 5V, you just fried your phone. Its not obvious at first, although in the documentation it does state that the output is terminal and USB. If you pay attention to the paperwork, its not hard to figure out. Nowhere in the documentation does it say the USB is 5V. It would, however, be easy to assume that USB is universal, and brick something valuable as a result.

I installed it in the same box as a low voltage motor controller for my DC ceiling fan. If the terminal connections were more substantial I would give it five stars. 16 gauge wire seems max, and that was tight. Easy to adjust and it's been working well. I like it.

取説が英文かなと思っていたら正確な日本語で良かった。ただ、書面は梱包でシワだらけだった。キャリブレーションがきちんと説明されていて解りやすかった。冷却フィンはモジュールから飛び出ないぐらいの大きさが欲しかった。3A以下での使用だが結構熱くなる。冷却ファンの取付け穴はあるが、ファンについての案内は無かった。DC18~20Vを12~14Vで使用している。

The directions that come with it are virtually crap. Your best bet is to find a video like i did (unless you know and understand electrical operations, which i didn't).The wiring was very easy, but you need to build the housing, and hat ended up being the first nightmare as the directions were not helpful.The second, make sure you have a very, very, tiny flat head screw driver. As I even struggled with the YouTube video (a tiny bit), I decided to say "F" it and just start turning the screws. The left is the volts, and the right, as far I can tell is for... I dint remember. I just know I turned that one around 30 times before it did anything.That said, it works great. I'm running an old laptop power supply to my HO train set. As it is putting out 19 volts, I had to get it down between 12v and 14v continuous power. It works perfect for that. I'd buy it again.

Just got it today and it seems to be working fine so far. At first, it didn't want to step down the voltage but made a change on the input voltage and it just started working. Not sure what that was but it works! It has like four voltage modes on one button and the other button to show the amps, turn on/off display. You have to assemble it but it is easy to assemble. No tools though just the screws, small plastic pillars, and a heat sink.Haven't got time to thoroughly test it yet but on a 5.03v output reading, multimeter showed 4.98v and I had a 220 ohm resitor with an LED and converter gave me 21mA reading. Using ohm's law you can see it's very close. So not bad!

Works with the Pi4 for me using the right 12v input, its just a shame the USB cant be automatily on after a power cycle,

I bought one of these to step down 24V to 12V for cooling fans on my 3D printer. So far, this little buck converter has been virtually flawless. It's easy to connect wiring, adjusting the voltage was a snap, and it looks pretty great, to boot!Pros:• Easy connections with screw-down clamp terminals• Easy to adjust outgoing voltage• Display can be adjusted to show incoming voltage, outgoing voltage, or both. And even amperage.• Looks fantastic. I love the clear, open "housing".• Includes small stick-on heatsink to keep things running coolly.• Everything fit together perfectly• Has a USB power output, in case you need to run USB devices from other power sources. (Likely need to reduce output to 5V.) This output can also be disabled.• Even has a spot to mount a small cooling fan to the clear acrylic over the heatsink.Cons:• No assembly instructions, though it's not overly complicated. (Hint: Look at the product photo for help.)• Voltage is off slightly, so I wouldn't call it overly-precise. Display says 12.0V out, and I measured 11.67V out. Good enough for my purposes.• Open housing can let in dust and debris, if that's a concern.• Included double-sided adhesive really doesn't stick all that well.Overall, the cons are pretty minimal for me. I'm really happy with this thing. We'll see how it does with longevity, but for right now it's been working great.
