I needed this for a small project running for long periods of time. I required 30Vdc and up to 3A. Often this is running at 30Vdc and just below 3A for 8 - 9 hours continuously. Fan runs intermittently but generally it makes no noise to worry about. The display is great having voltage, current and wattage.

This is a solid little supply, capable of up to 150 watts of output. Good for small devices and small computers. Navigating the interface is simple enough, the dial makes it simple to move through options, and you press in to confirm you want to drill into that option.The software comes on an included flash drive and is mostly usable. All the manuals are included on the same drive as well. The unit is programmable through the software and makes it fairly simple to create profiles to load different voltage scenarios so you don't have to manually adjust on the unit, though it does have a memory function built-in to do that if you wish.No fans, so it's silent. The display is very easy to read, clear, responsive and the output appears clean, no issues experienced when connecting some small test devices. It's not top tier, but it's pretty good.

Echt ein tolles Gerät.Sehr empfehlenswert !

Top Ware, schnelle Lieferung, super Preis!

Passt soweit zu empfehlen

Tolltes Produkt, funktioniert wie beschrieben und erwartet und vor allem es leise. Lüfter läuft wirklich nur in Hochlast.

Hohe Leistung gute Qualität. Passt alles.

Funktioniert bis jetzt ohne Probleme.

I had been looking at picking up a low-cost power supply for bench-top work for some time. I built my own awhile back using power from a DJI Inspire one battery charger (26V) and it worked well but I wanted something better. What really attracted me to this one was the display and the ability to interface with my computer. While I don’t really use the computer interface often, it’s nice to know it’s there.The display is bright and crisp and easy to read which is a huge plus. Interface is good as well, with values easy to change. Something some manufacturers could learn from (looking at you Hakko).

An sich ein nettes Gerät. Leider ist es nicht für empfindliche Messungen geeignet, wie die Störimpulse in der Ausgangsspannung zeigen. Man kann zwar die Gleichtaktstörungen mit einem handelsüblichen Funkentsörfilter (ich habe einen für 220V verwendet) sehr stark reduzieren. Dennoch bekam ich die Störungen damit nicht ganz weg. Dass das Gerät "Low Noise", wie angepriesen, sein soll, kann ich nicht bestätigen. Wenn der Hersteller die Störungen noch wegbekäme, gäbe es 5 Punkte. Da ich keinen anderen Anwendungsfall (z.B. Autobatterie laden) dafür habe, habe ich es zurückgeschickt.Pro:- Das Gerät ist kompakt und die Verarbeitung ist solide- geregelter Lüfter läuft nicht ständig- Das Gerät liefert die versprochene Leistung- Die Überlast-Sicherungen funktionieren- Spannungs und Stromregelungsmodus (wird automatisch erkannt)Con:- Kein Disconnect-Button (Man muss also immer das Kabel abstecken oder braucht einen externen Schalter)- Hochfrequente Störungen (für mich das No-Go-Kriterium)

The extent of my electronics knowledge I learned in college physics. I needed a variable power supply to build up some led lights with buck voltage controllers. I was sick of testing stuff using alligator clips and my truck battery.Ordered this for the low price, the nice screen and the output control button. I feel lucky to live in a time when this thing can be had for $85.I’ve had literally no issues with this thing from day one. I plugged it it, switched it on an everything was obvious. I really appreciate the layers of safety:- When turned on the output is off so you can set voltage, current and limits before juicing up your device.- overt limits set separately from settings so I cant accidentally exceed them when fumbling with the dialThe graph of voltage and current over time is useful when watching resistance rise with heat, also when thermal protections are tripped in downstream devices.I tested its voltage and current output with a light bulb and its behavior is as good as my multimeter.Only thing I don’t like are minor ui editing things:- the adjust timeout is too short- the digit editing transitions are in an odd orderOh: it comes with docs and software on a thumb drive. Probably full of malware I haven’t put it in my computer.Fortunately this device is a 100% knockoff of an OWON and owon has good docs online including specs for their spci syntax.Abestop website doesn’t mention this device, has no software, etc. But owon appears to be a real company that makes stuff.

Bin begeistert und die Ausgangsspannung scheint sehr genau und Stabil zu sein. Der Lüfter is unter Belastung leicht hörbar, aber das ist auch normal.

Great power supply
