DC Power Supply Variable, 0-30V 0-10A Switching Bench Power Supply with 20W USB & Type-C Quick-Charge, Encoder Corase & Fine Adjustment Knob, Output Switch, 4-Digit LED Display - SPS-3010V

Did the job nicely and good value too.

Perfect for my application requirements. Performs well , compact and well built.

I bought this as it can be set for current and voltage, current in 1mA steps and voltage in 10mV steps. though on the lowest currents it is slightly low when measured with my Fluke. The only reason for the 4 star rating is that the setting icons could be brighter, the main digital values are bright enough though, brightness can be controlled. It came with very short crockclip leads so it needs longer ones if not on your bench. Watt display is useful but i would like to have seen mAH timer for battery charging or a timer at least. though the price is great so i can forgive this feature. Setting is done by pressing the V or A button then turning the dial, it remembers the last setting while powered off (nice) USB outputs are useful.

Compact, reliable and very stable output. Easily adjusted voltage/current and very much a "plug-and-play" solution at a reasonable price. USB-A and USB-C sockets make it easy to connect items for charging. I haven't put the unit under great stress and, as yet, the cooling fan has not been used, so for me the unit has been silent. Attractive and clear display

Excellent value for money & quality & well constructed.

This power supply is really good, especially for the price. I’ve been using it every day since its purchase and I’ve not had any issues. I’ve since bought another one of these so I can have 24v and 5v lines simultaneously. I’d definitely recommend for anyone thinking of buying a variable power supply.

Doesn't allow adjustment as advertised. Half of the buttons do nothing, those that do something don't allow fine-grain adjustment as advertised. It got 5000 5-star reviews from who exactly?

It has all I need from an adjustable PSU. It also has an output on/off switch which is a handy thing, most of similar units don't have this

Ottimo prodotto funziona molto bene fornisce una tensione stabile e ottima sia per uso obbistico che professionale. È leggero è quindi un alimentatore switching ma di buona qualità presenta anche il collegamento a massa per applicazioni audio ad esempio

Lo qué más me sorprende es lo pequeña que es y su bajo peso, ideal para el laboratorio de electrónica. Trae cable de red eléctrica y otro cable de bananas a pinzas de cocodrilo. Se puede ajustar de forma muy precisa tanto el voltaje como la intensidad con un error de medida de 0,15 voltios respecto a lo visualizado en su display, comprobado con un multimetro Fluke. No se calienta nada y el ventilador no parece que haga ruido. La salida USB de 5 voltios es todo un acierto, me permite tener conectado un osciloscopio portátil o cargar mi movil y la tablet. Funciona perfectamente para lo barata que es y cumple de sobra para mi laboratorio. Recomendada.

Muito boa!

Have not used it for long, but it seems good som far. East to use.

This power delivers the power as advertised. It will produce the current with compromise, and the overcurrent protect and constant current setting work great. I have always been leery of power supply specs as many times they don't deliver. This power supply delivers! READ the instruction manual and there won't be the complaints I see in the low star reviews. The output voltage is right on with my meter and scope so that is great that I can trust what I am seeing on the display. I inadvertently shorted it out a couple of times and it shut down so fast there was next to no spark reaching the 10Amp shutdown. The unit is physically smaller than you might envision from the picture but it fits the bench well and the size doesn't limit the performance. There is a cooling fan that operates much like a CPU fan and is constantly variable depending on load, under light loads 2A or less I don't notice it coming on. The output is quite clean, a bit of ripple around 10mV (reading on scope set at AC input) but that has no effect on circuits I am using it for since they normally have an input power capacitor anyway that smooths out any ripple. One of the best power supplies for the money and I would stack it up against units costing 4 times more. If I had to make a complaint about something I would say the adjustment knob is a little on the cheap side but I plan to change that and the power leads they supply are light duty, not knowing they supplied any I purchased a good set at the same time. And if that is all I can complain about, then it is negligible. The display is nice and bright (also dimmable) and the screen came with a plastic film to protect it during shipping, some complain about scratches and no protective film, perhaps they received previous returns units from those not understanding how the supply works and returning them, again read the instructions! There is also a video explaining the unit so you can see what it does before you buy. Totally pleased and plan to but another one or two to outfit my bench.
