DC power supply (0-30V,0-5A) adjustable, switching power supply, mini high precision 4-digit display with USB fast charging interface, variable lab bench power supply, output on/off/encoder knob

Muy buen producto, aspecto profesional.

120 v 3 amper diye aldığım güç kaynağı 30 v 5 amper olarak geldi.iade ettim.

So glad I finally bought a bench supply. And checked on videos online to see which one is best at this price range. It does so much more than the cheapest ones. If you set the current limit, and it is reached it tells you it is in current limit mode and then the voltage drains down. You can also set it to shut off with Over Current Protection, where an alarm will sound and it will cut power. I found the leads more than adequate with the alligator clips and spade terminals, which I prefer to the banana clips. Readout is nice and clear with a fairly good update rate so you can see changes happen quickly. You can even adjust the baud rate in the options to make it quicker and lower the screen brightness. USB port also came in handy, although you cannot read the current draw for this, and the manual doesn't mention what it's limit is. I powered an Arduino and charged a phone off it, so it was fit for purpose. Adjusting everything is easy with pushing the knobs to change which digit you want to adjust to do fine or rough adjustment from 1 / 0.1 / 0.01 etc. It would be nice if it remembered which digit you were last on though, as it keeps defaulting to fine adjustment and takes a bit of remembering to push it first before turning it. Only thing is the beeps are a bit annoying, which wasn't a problem at first, because the manual lets you turn it off by going into settings if you hold down the output button for 5 seconds. However, it doesn't remember what you set each time you turn it off so have to do it all again every time. This is silly because it remembers all your other settings, even when you unplug. I might just open it up and cover the buzzer with a piece of tape to make it less noisy.

Utilissimo per interventi su piccoli dispositivi ne ho apprezzato la praticità e la funzionalità , molto soddisfatto

Was soll ich sagen - das Gerät ist kompakt, leicht und solide. Die Verarbeitung wirkt hochwertig, das Display ist sehr gut abzulesen und die Bedienung ist kinderleicht. Alles funktioniert auf Anhieb so wie erwartet (Anleitung benötigt man nicht wirklich) und mit 150 Watt sind auch wirklich alle Szenarien abgedeckt. Der USB-Schnelladeport ist nochmal eine sehr gute Ergänzung. Mit den passenden Steckern und Adaptern kann man mit dem Gerät wirklich alles betreiben bzw. aufladen, die einfache Einstellung des maximalen Ladestroms ist hierfür optimal. Bevor man sich diverse Ladegeräte einzeln kauft, hat man von so einem Gerät natürlich viel mehr. Damit kann ich auch bei Bedarf die Motorrad- oder Autobatterie mit dem richtigen Ladestrom aufladen, ohne hierfür separate Geräte zu Hause stehen zu haben.
