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

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.

nicely built seems to work well.ease of use.

Nice power supply. Accuracy is pretty good too. USB is handy to keep my phone topped up (although seems a bit slow?) Absolutely ghastly crocodile clips on the leads, huge (how many amps do they think they are gonna deliver?), plus the jaws misalign on first use. I cut them off and put more sensible ones on at first use. Other than that it seems good. Good price, could have got it a bit cheaper direct from China, but no guarantee the local delivery company will actually deliver it.

Perfect DC power supply unit, well packaged received in perfect condition, working great, thank for fast delivery

Good product

This psu is great value for money and have been using it for many things. Good voltage control and short circuit protection - very happy with this purchase!

Was nice to finally get a bench power supply. This thing does what it says provides plenty of voltage plenty of current and you can set maximum wattage or current. There’s even a shut off if it detects a short or goes over current, I like the USB charger on the front it’s kind of handy to have on the desk. My only feedback would be to swap the power switch and the output switch, the power switch that turns the whole thing on is in the middle of all the knobs instead of somewhere at the edge

Doing well so far. Accurate output

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

Mi serviva un alimentatore duale con cui poter simulare due lipo 3S collegate in serie, un discreto alimetatore duale costicchia parecchio e a conti fatti ho preferito prenderne due uguali ed usarli in serie, devo dire che la comodità di regolare la tensione con un encoder ottico è spettacolare, può essere variata decidendo se agire sui volt, i decimi di volt o per variazioni davvero piccole anche sui centesimi di volt rispetto ad altri alimentatori che ho con il classico potenziometro qua la regolazione è fluida senza inceppamenti o salti dovuti all'usura del potenziometro, inoltre come alimentatore presumo sia anche ben tarato visto che entrambi settata la stessa tensione danno anche gli stessi valori di assorbimento. Il tutto lavora sui 24v che a loro volta vengono ridotte con i tipici stepdw e alimentano un arduino mega e parecchi motori in dc di diversi voltaggi, senza nessun problema o reset di arduino. Non posso esprimermi in merito alla pulizia della tensione o ripple residuo ma almeno per le mie prove da hobbista sono molto soddisfatto.

Genau, dass was ich gesucht hatte. Das Labornetzteil kam SEHR gut verpackt hier an und machte sofort einen Spitzen Eindruck. Die Spannung und den Strom kann man schrittweise mit einem Poti erhöhen oder absenken, oder Stelle für Stelle direkt eingeben. Das Piepen bei jedem Schritt ist auch abzustellen und die Anzeige V, A, Watt Spitzenmäßig abzulesen. Die Genauigkeit ist mindestens 1 Stelle hinter dem Komma 100 Prozent genau, danach weist sie um 1 bis 2 Punkt an. Aber wer benutzt ein Labornetzteil auf zwei Stellen hinter dem Komma. Ich denke mal das solche Leute eh ganz was anderes kaufen. Die beigelegten Kabel sind meiner Meinung nach auch sehr gut, denn wir sprechen hier von einem Gerät unter 60 Euro. Klein handlich und Leistungsstark mit 5 Amper. Ich hatte Eine Hupe im Keller, die hat 12 Volt 4,5 Amper und das liefert das Netzteil auch. Hatte die Hupe schon lange nicht mehr so laut gehört. Die Ausgabe der Spannung ist auch einzustellen. Sprich ob beim Einschalten des Netzteils direkt Spannung an den Klemmen anliegen soll oder erst nachdem man den Output Knopf drückt. Also für alle die zuverlässige Leistung bis 30 Volt benötigen, ist das hier eine klare Kaufempfehlung.

Qualitatif, simple de prise en mains et fiable. Très utile en bricolage amateur.
