DC Power Supply Variable, 0-32V 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

High quality and precise.
I just totally love this DC power supply product. It’s very precise for any voltage output that you want and it’s really neat about how precise the power draw is for the amps and watts for anything you have hooked up to it. I highly recommend it to anyone who wants a high quality power supply.

Ad said brightness is adjustable but I haven’t figured out how yet
If I just knew how to adjust brightness of the white display (assuming it can be adjusted like stated in the ad) I’d give the seller 5 stars. So far I’ve looked around and found brightness adjustments for other of the Jesverty models but not the one I bought. Oh well, I just have to pause a moment when looking from the supply display to breadboard so my eyes can adjust. Mind you the brightness is not an issue in a well lit setting; but during times I let the project run late into the evening is when I wish I could turn the brightness down.One other negative is the output jacks do not have the small thru hole which would allow putting a bare wire into the hole and then snugging down the jack onto it. Thankfully I bought a set of banana plug cables with alligator clips on other ends.That was pretty much the only problems I’ve had with the Jesverty power supply. Everything else is working just as advertised. I have sometimes wondered about having the coarse/fine knobs for volt/amp settings. The coarse setting alternates between the two left most digits while fine alternates the right most two digits (beware! If you do this adjustment with either volts or current below 10.00 you will be changing the tenths digit rather than only the ones or tens position) For example I planned on changing the amps coarse setting of 1.500 to 3.500 and the indicated position being changed was the tenths so I went 1.6, 1.7, etc rather than 2.5 and 3.5. Pay attention to the highlighted digit when making adjustments.I like the output power on/off function so I can make adjustments w/o having to disconnect the power leads. I also appreciate having a watt reading in the display – I won’t be grabbing the calculator nearly as often. I have noticed the watt reading changes with voltage or amps so I suspect it may be a calculated value rather than actual. For instance when charging a battery the amps will constantly be changing yet the watt display doesn’t pick up on those minor changes unless there’s a change to volt/amps of the display.I guess it’s too much to ask for millvolt level displays with a switching power supply; but I frequently work with very small adjustments such as 2-5 millivolts. Granted the display shows 0.001 for millamps so would be nice if the volt display would switch to 9.999 when working below 10 volts. Of course the display is well filtered so you don’t notice the ripple of the power supply output – the spec value of <0.5% Vp-p is consistent with what I saw on peak reading of Fluke 87 mulitmeter as well as o-scope. No real surprises there.The USB-A and C outputs are both limited to 20 Watts or 5 volts at 3.6-4.0 amps from what I've found. I haven't tried to see if the USB-C output will support any of the other possible voltages - documentation for the supply doesn't say anything either way. In the future I plan to get a couple USB cables with cut off ends so I can use the 5 volt output for electronics projects while at same time using the regular output for 6-15 volt needs.The fan is temperature driven so in my low <200 watt testing I have barely noticed the fan operation. I imagine it could be somewhat noisy once the supply is providing >500+ watts but that’s not something I’ve been able to check.I’m quite pleased with the Jesverty power supply. It should work well for general ps needs and the price/quality has me very satisfied with this purchase. A good buy in my opinion.

Magic box make angry pixies tickle gronk. Gronk like.

Simple to use. Love it!
This is so simple to use. Comes in handy for all kinds of power needs. I use it for charging custom batteries and powering small circuits. I haven’t used it in critical use cases where ripple is a big deal so it’s working fine for me.

Ma note aurait plutôt été de 4.5 sur 5 mais faut choisir entre 4 et 5.Cette alimentation est correcte, l’interrupteur est en façade et non à l’arrière, elle est légère aussi comparé à ma première alimentation qui a un transfo dedans qui fait son poids.Maintenant les quelques points où l’on peut trouver à redire mais cela est atténué de par son prix.Régler finement tension ou courant est difficile surtout pour de faible valeurs, on sent la présence d’un condensateur, lorsque l’on bouge le bouton de réglage il faut attendre que la valeur se stabilise sous peine de régler trop haut ou trop bas par rapport à la valeur désirée.Ensuite un point non crucial mais que je trouve dommage, c’est d’avoir mis de “simples” fiches bananes au lieu de fiches bananes dites “de sécurité”. Car si vous avez des fiches bananes de sécurité mâles vous ne pourrez pas les rentrer dans les fiches bananes femelles de l’alimentation, alors que l’inverse est possible.En mettant des fiches de sécurité femelles sur l’alimentation, les deux types de fiches bananes mâles sont insérables.Pour ma part je vais les remplacer en faisant “sauter” au passage la garantie, c’est cela ou la renvoyer…Je recommande quand même cette alimentation pour les amateurs d’électronique qui veulent un alimentation sans se ruiner.

I had a Longwei 30V 10A for changing a 24V 8S battery bank, which worked great, never any problems!!But then I bought a Sky Toppower PS6005H 60V/5A to charge a 48V 15kw battery bank, lasted 2 months, Toroid melted down), ran hot (could be used as a heating source), with fan a blazing! Contacted the manufacturer…No reply! Obviously they know they have a 💩 product!Purchased the Jesverty to replace the Sky PoorPower, but was sceptical because of it’s size and reasonable price. Well, it’s been running ever since I purchased it in the spring, every night 7pm to 7am weekdays, and 24hrs/day on weekends…Wide Open, 60+Volts and 5.2 Amps. Fan runs at a medium speed, very quietly and with virtually no heat!…can’t Stress that enough!!So far, a fantastic buy!…Actually, it has more than paid for itself!
