DC Power Supply Variable, 0-30V 0-10A Adjustable Switching DC Regulated Bench Power Supply with High Precision 4-Digit LED Display, 5V/2A USB Port, Coarse and Fine Adjustment SPS-3010

Great psu. Cant quite get full current out most of the time(seems to top out at 2.5A at higher voltage), but for a cheap psu it is great. I find this works well for titanium anodizing, but it is slow on large pieces due to the high surface area to amperage ratio. It is super simple to use. Feels super light, but what can ya expect from a cheap psu.

With consistent performance and user-friendly operation, this power supply is an essential tool for any electronics setup.

Summary: This is the 3rd power supply I have bought since 2020. The first two were the same 30V/6A (180W), one blew out, and the other is still working. Wanted a bit more power when charging 12V AGM batteries, so ordered this unit, which is a 30V/10A (300W). Overall, very satisfied with the performance. Use-Cases: In addition to charging 12V AGM batteries, I use this bench top power supply to charge lithium batteries. Have a couple of Milwaukee M18 battery packs that are older, and sometimes drop below the point where the standard charger will recognize it, so after opening the case, I can individually charge the cells. I typically start with this charger, and then finish off the cells with an XTAR lithium battery charger. Sometimes the XTAR stops at 4.0-4.1V, so I use the power supply to drive it to 4.20V when top balancing the pack. Observations: This unit has a robust cooling fan, and when running at high current (above 5A) the fan kicks on. While the added noise might bother some, this is the purpose of the cooling, to keep the power supply within the allowed temperature range, which can lead to long term reliability. This 300W power supply's cooling fan is definitely moving way more air volume than the 180W one. Selecting this one was easy because it was the #1 rated offering in "Lab Power Supplies", with over 1000 ratings/reviews. Recommendation: Last time I researched power supplies was 2021, so I spent an hour looking at a bunch of different options in the $50-200 range. I looked at a couple of dual units, essentially two of these in one, with the ability to parallel or series the output, but decided against those offerings which were in the $150 price range (3x the cost). The same can be done manually (with the requisite knowledge) with two individual units). In general, if you buy a higher rated supply, and run it at half power, it should last longer than a smaller unit running at full power (all the time). Pros: Jesverty is a specialty power supply manufacturer, many with great ratings/reviews; cost is comparable to similar offerings. Cons: None for now. Conclusion: At $50 for a 30/10A (300W) power supply, rating this 5-stars.

Decent for a basic power supply, but I can't stand the voltage adjustment. The coarse knob gets you somewhere in the right neighborhood, and then the fine dials it in. Both are ridiculously sensitive. I would prefer a digital adjustment knob. As far as performance, it seems to work well. I haven't tested more than a couple of amps so far, but it worked well for my needs. The device looks great, and has a bright screen.

Knobs feel cheap but it’s accurate and works well, fan isn’t too loud and it’s lasted me a while under frequent use

Been runing for a few days and it works as expected. like most switch mode supplies ita RF noisy. But for testing stuff and charging batteries it works well.

Great product Easy set up Easy controls Doesn't take up too much real estate on workbench

Excellent quality Works Excellent Great value for the money

Ottimo alimentatore, tensione di uscita regolalabile finemente e molto stabile. Ho provato a misurare la tensione prodotta con un volmetro digitale e leggevo la stessa tensione mostrata dal display dell'alimentatore. Utilissimo nello svolgimento del lavoro in laboratorio, oer ora affidabile e bello esteticamente. Il display è sufficientemente grande e leggibile. Importante non è rumoroso, la ventola entra in funzione quando necessario e il rumore è impercettibile. Ritengo più che adeguato il prezzo relativamente alle prestazioni che offre. Ottimo l'utilizzo per alimentare dispositivi elettronici e led. Consigliato

An awesome tool for the money paid. Works well and outputs the desired voltage and current without problems. Extremely happy with this purchase!

Works as advertised. Allows to set both Vol and Amp to desired levels. In higher settings the coils will whine but it doesn't affect the operation. Good value for money.

Para lo que se le necesita, alimentar pequeños prototipos electrónicos y reguladores eléctricos funciona extraordinariamente. Evidentemente habrá otros mas completos, pero para la mayor parte de las cosas es perfecta.

Excelente!
